What does it mean when a dog sheds a lot?
Definition and Difference Between Shedding and Hair Loss
Dog hair on the sofa, on clothes, on the kitchen floor—for many dog owners, this is simply part of everyday life. But not all shedding is the same, and the difference between a normal coat change and actual, pathological hair loss is crucial. During a natural coat change, your dog sheds its old coat evenly across its entire body, without bald spots, skin changes, or itching.
Pathological hair loss, known in veterinary medicine as alopecia, looks different: It occurs in localized areas, forming bald patches, may be accompanied by redness or dandruff, and often progresses asymmetrically. If you notice that your dog’s coat is becoming increasingly thin in a specific area or that he is scratching and licking that area intensely, you should take a closer look. The difference is usually visible to the naked eye; healthy hair leaves no marks on the skin.
Here’s a simple way to check: Stroke your dog’s fur against the grain. If you see an evenly dense undercoat and healthy, pale pink skin underneath, that’s a good sign. If, on the other hand, you find red, scaly, or even open areas of skin, it’s a good idea to have your dog examined by a veterinarian. This initial visual check costs nothing and gives you a quick assessment in just a few seconds.
How long does the shedding season last for dogs?
The classic coat change occurs twice a year: in the spring, when the thick winter coat is replaced by a lighter summer coat, and in the fall, when the coat prepares for the colder months. The duration varies considerably depending on the breed, age, and living conditions. For most dogs, a shedding phase lasts between three and eight weeks.
Dogs that live primarily indoors often shed moderately year-round because the consistent warmth and lighting prevent a clear seasonal trigger. A Husky that lives outdoors, on the other hand, may seem to lose half its coat within a few weeks in the spring; this is completely normal and, while it may look alarming, is nothing to worry about. The same is true for Bernese Mountain Dogs, whose intense shedding phase often comes as a real surprise to first-time owners.
Very young dogs going through their first coat change—from puppy to adult fur—may also shed heavily for a short time. This transition usually occurs between 6 and 12 months of age and is a normal process. So, before you worry, consider the breed and the timing of the coat change.
Breed-related differences: Which breeds shed the most?
Not every dog sheds the same amount. As a general rule, dogs with a double coat—that is, a dense undercoat and an outer coat over it—shed significantly more than single-coated breeds. Among the best-known “shedding machines” are the Siberian Husky, Alaskan Malamute, Samoyed, German Shepherd, Golden Retriever, Labrador Retriever, and Bernese Mountain Dog. For these breeds, the amount of shedding in the spring can be so substantial that entire clumps of fur come loose.
Breeds with curly or textured coats, such as the Poodle, the Lagotto Romagnolo, or the Portuguese Water Dog, do shed hair; however, the hair gets caught in their coats and doesn’t fall to the floor, which is why these dogs are often mistakenly considered “non-shedding.” Instead, their coats mat more quickly and need to be trimmed regularly. Even short-haired breeds like Beagles or Dalmatians shed; their short, bristly hairs get deeply embedded in fabrics and are particularly difficult to remove.
For dog owners who prefer a low-shedding breed—whether due to allergies or for comfort—it’s advisable to do thorough research beforehand. Even dogs labeled as hypoallergenic produce saliva proteins and dander that can trigger allergies. Shedding itself cannot be completely prevented in any breed, but it can be significantly reduced if you make the right adjustments.
Causes and Risk Factors for Severe Hair Loss in Dogs
Nutritional deficiencies as the most common internal cause
If your dog is shedding more than usual outside of its normal shedding season, it’s worth taking a closer look at the quality of its food. Veterinary medicine is clear on this: poor nutrition is one of the most common internal causes of a poor coat and increased hair loss. Specifically, dogs often lack essential fatty acids, sufficient biotin, zinc, and high-quality proteins—all of which are building blocks that the body needs directly for healthy hair follicles.
A dog that is fed low-quality dry food for months—food that is sufficient in calories but low in micronutrients—often develops a dull, brittle coat and sheds more than average. Hair follicles are metabolically highly active structures that must be continuously supplied with nutrients. If these nutrients are lacking, the body stops producing new hair—at first imperceptibly, then increasingly visibly.
A real-world example: A three-year-old female Labrador is brought to the veterinary clinic with diffuse hair loss and a dull coat. The blood work and skin examination are normal, so the veterinarian initially recommends a change in diet, including the addition of omega-3 supplements. After six to eight weeks, a significant improvement is already evident. This scenario is not uncommon in veterinary practice; in fact, it is the norm.
Stress-related factors: Can psychological stress lead to hair loss?
Yes, dogs can also develop hair loss due to chronic stress. Similar to what happens in humans, prolonged stress activates the sympathetic nervous system and leads to increased cortisol release. This stress hormone disrupts the natural hair growth cycle and can cause more hairs to enter the resting phase at the same time, resulting in hair loss.
Common sources of stress for dogs include moving, the loss of a companion, being overwhelmed by intense training, fear of loud noises, or an irregular daily routine. A dog that is left alone for eight hours a day and does not receive sufficient mental stimulation experiences chronic underlying stress, which eventually takes its toll on the coat.
Stress-related hair loss is usually reversible. Once the underlying cause has been addressed and the dog is back in a stable, calm environment, hair growth typically returns to normal within two to three months. As a complementary measure, adaptogenic support may be beneficial; the Ayurvedic medicinal plant Withania somnifera (ashwagandha) is traditionally used in veterinary herbal medicine to reduce stress and support the immune system and is worth trying as a supplementary measure. However, if symptoms of stress persist or are severe, you should always consult a veterinarian first to rule out any medical causes.
Environmental and Climate Factors
The intensity of shedding is largely controlled by light and temperature. Photoperiodism—the body’s response to changes in daylight hours—triggers the biological start of shedding phases. Dogs that live primarily indoors under artificial lighting often do not receive a clear seasonal cue and therefore shed lightly to moderately year-round, rather than in concentrated bursts.
Dry, heated air in the winter is an often-underestimated factor: It strips moisture from the skin, irritates the hair follicles, and can lead to increased shedding and dandruff. If you notice that your dog is shedding more and scratching during the winter months, even though there is no parasite problem, the heated air could be a contributing factor. A humidifier and a tailored diet rich in skin-nourishing nutrients can make a noticeable difference here.
Environmental chemical exposure, excessive use of floor cleaners, harsh shampoos, or frequent contact with chlorinated water can also weaken the skin barrier and increase hair loss. Sensitive dogs, in particular, often react to such irritants with increased scratching and diffuse hair loss.
Skin Diseases and Parasites
Fleas, mites, fungal infections, and bacterial skin diseases are among the most common external causes of localized hair loss. Mange (caused by Sarcoptes mites) typically begins at the edges of the ears, the elbows, and the abdomen and leads to intense itching, scabs, and bald patches. Demodectic mange, on the other hand, often occurs without itching and presents as circular, hairless patches, particularly in young or immunocompromised dogs.
Ringworm—contrary to its name, it is not a worm but a fungal infection caused by dermatophytes—produces characteristic round bald patches with scaly edges. This infection can also be transmitted to humans, which is why hygiene precautions are particularly important if an infection is suspected. A veterinary evaluation involving a fungal culture or a Wood’s lamp test is absolutely necessary in this case.
Conditions such as leishmaniasis or Cushing’s syndrome can also lead to significant hair loss; in these cases, hair loss and a poor coat are often just one symptom among many, accompanied by systemic changes such as weight gain, increased thirst, or muscle wasting. If hair loss is part of a broader set of symptoms, a comprehensive diagnostic evaluation by a veterinarian is essential.
Symptoms and Warning Signs: When Does Excessive Hair Loss Become a Problem?
Common Hair Loss Symptoms vs. Warning Signs
The biggest challenge for dog owners is distinguishing normal shedding from a real problem. The following comparison helps with identification:Normal symptoms of shedding:- Even hair loss distributed throughout the entire body- No changes to the skin (no redness, no dandruff, no sores)- The dog does not scratch excessively and sleeps normally- The amount of hair increases for four to eight weeks, then returnsto normalSeverity: Mild | Urgency: Monitor the situation; this isa normalshedding cycle. Warning signs that require further evaluation:- Bald spots that do not regrow hair- Symmetrical hair loss on the flanks, belly, or back (possible hormonal issue)- Dull, brittle, lifeless coat with no seasonal cause- The dog repeatedly licks, scratches, or bitesthe sameareasSeverity: Moderate | Urgency: See a veterinarian within 1–2 weeks
Emergency Warning Signs: When Should You Take Your Pet to the Vet Immediately?
🚨 EMERGENCY ALERTBald, circular patches with scaly or reddened edgesPlot: Go to the vet immediately; possible fungal infection (ringworm), which can be transmitted to humans.🚨 EMERGENCY ALERTOpen, oozing, or bleeding wounds caused by scratching or bitingPlot: Go to the vet immediately—there is a risk of infection and significant distress.🚨 EMERGENCY ALERTIntense, persistent itching that prevents the dog from sleeping, combined with widespread hair lossPlot: Go to the vet immediately—it could be an allergic reaction, parasites, or an autoimmune disease.🚨 EMERGENCY ALERTHair loss accompanied by fever, lethargy, loss of appetite, or excessive thirst and urinationPlot: Go to the vet immediately; hair loss can be a symptom of a systemic disease (e.g., thyroid problem, Cushing's syndrome).How can you tell if hair loss is caused by an underlying medical condition?
Hair loss caused by an underlying medical condition is almost always distinguishable from normal hair loss by accompanying symptoms or a distinctive pattern. A simple diagnostic checklist can help you assess the situation: Where is the fur falling out—evenly or in localized patches? How long has the problem been present—seasonal or persistent? Are there any skin changes, such as redness, dandruff, scabs, or an odor? Has your dog’s overall well-being changed?
Hormonal disorders, such as hypothyroidism, often manifest as symmetrical hair loss, accompanied by weight gain, lethargy, and sensitivity to cold. This hair loss develops slowly and gradually, often to the point where dog owners say in hindsight, “It developed over months; I didn’t notice it until it was too late.” Being aware of these gradual processes is an important first step.
If hair loss is suspected to be caused by an underlying medical condition, the veterinarian will typically order a blood test (to check hormone levels, kidney function, and liver function), a skin scraping to check for parasites, and possibly a biopsy. The cost of a comprehensive dermatological evaluation in Switzerland ranges from approximately CHF 180 to 350, depending on the scope of the tests performed. This is a worthwhile investment, because without an accurate diagnosis, any treatment will be ineffective.
Diagnosis: How Does the Veterinarian Determine Why Your Dog Is Shedding Heavily?
Initial Examination and Medical History
A veterinary evaluation for severe hair loss always begins with a detailed medical history. The veterinarian will ask you: How long has your dog been shedding excessively? Are there seasonal fluctuations? Has the dog’s diet changed recently? Have there been stressful situations, moves, or changes in the household? Does the dog scratch, lick, or bite at specific areas? This information helps the veterinarian narrow down the possible causes.
This is followed by a physical examination during which the skin is carefully inspected. The veterinarian looks for skin changes such as redness, dandruff, scabs, pustules, or changes in pigmentation. He or she examines the coat’s texture, the distribution of hair loss, and whether the hairs come out easily. This initial examination typically costs between CHF 80 and CHF 150 in Switzerland and serves as the basis for all further treatment.
An experienced veterinarian can narrow down many possible causes simply through visual inspection and palpation: Symmetrical hair loss often indicates hormonal problems; localized bald patches accompanied by dandruff suggest fungal infections or parasites; and diffuse hair loss with a dull coat frequently points to nutritional deficiencies. The clinical examination is therefore the first and most important step in diagnosis.
Skin scraping and fungal culture
If a parasitic infestation or fungal infection is suspected, the veterinarian will perform a skin scraping. During this procedure, a scalpel is used to gently remove a superficial layer of skin, which is then examined under a microscope. This allows for the detection of mites such as Demodex or Sarcoptes, as well as fungal spores. The procedure is largely painless for the dog and provides initial results within a few minutes.
A fungal culture is more time-consuming: hair samples and skin flakes are placed on culture media and incubated. Dermatophytes require up to three weeks to grow before a definitive result is available. This test costs approximately CHF 80–150 in Switzerland and is essential if ringworm or other fungal infections are suspected, as these conditions are also contagious to humans.
In addition, a Wood’s lamp (UV light) can be used, under which certain types of fungi fluoresce. However, not all dermatophytes exhibit this reaction, which is why, although the Wood’s lamp is a quick screening method, it can never replace a fungal culture. The combination of a clinical examination, skin scraping, and fungal culture enables an accurate diagnosis of parasitic or infectious skin conditions.
Blood Tests for Hormonal Causes
If the veterinarian suspects that hormonal imbalances are causing the hair loss, he or she will order a complete blood count. Typically, thyroid levels (T4, TSH) are measured to rule out hypothyroidism. Hypothyroidism is one of the most common hormonal causes of symmetrical hair loss, accompanied by weight gain, lethargy, and sensitivity to cold.
If Cushing’s syndrome (hyperadrenocorticism) is suspected, cortisol levels are measured, either as a baseline value or via an ACTH stimulation test. Cushing’s syndrome often manifests as a thinning coat, a distended abdomen, increased thirst, and frequent urination. Diagnosis is more complex and costs between CHF 200 and CHF 400 in Switzerland, but it provides clear results.
Liver and kidney function tests are also often included, as chronic organ diseases can negatively affect coat quality. A comprehensive blood workup gives the veterinarian a complete overview of your dog’s health and helps identify hidden conditions that may manifest as hair loss, among other symptoms. This investment in thorough diagnostics pays off in the long run because it enables targeted treatments.
Allergy Tests and Elimination Diets
Food allergies and environmental allergies are other common causes of skin problems and hair loss. If a food allergy is suspected, the veterinarian will recommend an elimination diet: For eight to twelve weeks, the dog is fed exclusively a new source of protein and a new source of carbohydrates that it has never eaten before (e.g., horse meat and sweet potatoes). At the same time, all treats, chew toys, and table scraps are eliminated.
If the symptoms improve significantly during the elimination diet and reappear when the old food is reintroduced, a food allergy is confirmed. This diagnostic method is inexpensive but requires discipline and patience. Many dog owners underestimate how strictly the diet must be followed; even a single treat can skew the results.
Allergy tests for environmental allergens (pollen, dust mites, mold) can be performed using blood tests (serological allergy test) or skin tests (intradermal test). In Switzerland, the cost ranges from CHF 250 to 500. These tests help identify specific allergens but do not provide a cure; they are primarily used to help patients avoid specific allergens or to plan desensitization therapy. Veterinary supervision is essential if an allergy is suspected.
Treatment and Therapy Options for Severe Hair Loss
Dietary Changes as a Basic Treatment
In most cases of excessive hair loss, a change in diet is the most important therapeutic measure. If nutritional deficiencies are the cause, the first signs of improvement often appear after just four to six weeks. Look for high-quality food with a clearly stated meat source as the first ingredient, a balanced omega-3 to omega-6 ratio, and sufficient micronutrients such as zinc, biotin, and B vitamins.
In addition, omega-3 supplements (salmon oil, flaxseed oil) or brewer’s yeast can be added to their diet. These dietary supplements cost between CHF 15 and CHF 50 per month and support skin regeneration from the inside. Important: Dietary supplements are never a substitute for a veterinary diagnosis and treatment; they are always only a complementary measure. If problems persist, you should consult a veterinarian first.
If your dog is put on an elimination diet, be sure to follow it strictly. Improvement often takes eight to ten weeks to become apparent, so patience is key. The cost of hypoallergenic specialty food is approximately CHF 80–150 per month, depending on the dog’s size. While this may seem expensive at first glance, it saves on veterinary costs in the long run and significantly improves your dog’s quality of life.
Drug Treatment for Underlying Conditions
If the cause of hair loss is an underlying condition such as hypothyroidism, Cushing’s syndrome, or a bacterial skin infection, medication is necessary. In cases of hypothyroidism, the dog is given daily thyroid hormone tablets (levothyroxine), which must be administered for life. The cost is approximately CHF 20–40 per month, depending on the dose.
Cushing's syndrome is treated with medications such as trilostane, which inhibit excessive cortisol production. The treatment is complex, requires regular blood tests, and costs between CHF 100 and CHF 250 per month. Neither of these hormonal disorders is curable, but they can be well controlled with consistent therapy; hair loss usually subsides after three to six months.
Bacterial skin infections (pyoderma) are treated with antibiotics, often in combination with medicated shampoos. A typical two- to three-week course of antibiotics costs approximately CHF 50–120. For fungal infections, systemic antifungals (e.g., itraconazole) are used; treatment lasting six to eight weeks costs approximately CHF 150–350. Medication should always be administered under veterinary supervision to prevent side effects and monitor the success of treatment.
Parasite Control for Mite and Flea Infestations
Consistent treatment is crucial in the event of a parasite infestation. Fleas are controlled using modern spot-on treatments, tablets, or collars. It’s important to treat not only the dog but also its environment: beds, blankets, and carpets must be thoroughly cleaned or washed. The cost of a three-month flea treatment is approximately CHF 40–80.
Sarcoptic mange is treated with special antiparasitic medications, often in the form of injections or spot-on treatments. Treatment lasts several weeks and usually requires two to three repeat doses at two-week intervals. The total cost is approximately CHF 100–200. Demodex mange, especially the generalized form, is more difficult to treat and often requires several months of therapy with ivermectin or moxidectin.
Fungal infections such as ringworm are treated with antifungal shampoos and systemic antifungal medications. The environment must be thoroughly disinfected, as fungal spores can survive for months. Treatment lasts at least six weeks—often longer—and costs between CHF 150 and CHF 400. For all parasitic and infectious diseases, veterinary supervision is essential to prevent the development of resistance and ensure the treatment’s success.
Skin Care and Supportive Measures
In addition to treating the underlying cause, supportive skin care measures play an important role. Medicated shampoos containing soothing ingredients such as oat extract, aloe vera, or chlorhexidine can relieve itching, strengthen the skin barrier, and remove loose hair. During periods of acute skin problems, bathe your dog once or twice a week with a mild, veterinarian-recommended shampoo.
Avoid harsh shampoos or human products, as these can disrupt the pH balance of a dog’s skin (pH 7–7.5) and further damage the skin barrier. High-quality veterinary shampoos cost about CHF 20–40 per bottle and last several months with regular use.
Regular brushing removes loose hair, promotes blood circulation in the skin, and distributes natural skin oils evenly throughout the coat. During shedding season, you should brush your dog daily; otherwise, two to three times a week. A good undercoat brush (e.g., Furminator) costs about CHF 30–60 and pays off in the long run by keeping your dog’s coat healthy. Important: Brush gently and avoid applying excessive pressure, which could irritate the skin.
Costs and Insurance: How Much Does Treatment for Excessive Hair Growth Cost in Switzerland?
Diagnostic Costs
The cost of diagnosing excessive hair growth varies considerably depending on the scope of the tests. An initial veterinary examination, including a medical history and physical examination, costs between CHF 80 and CHF 150 in Switzerland. If a skin scraping is also performed, an additional CHF 40–80 is charged.
A fungal culture costs approximately CHF 80–150, while a complete blood count, including thyroid levels, costs CHF 150–300. If Cushing’s syndrome is suspected, an ACTH stimulation test may be necessary, which costs an additional CHF 150–250. Allergy tests cost CHF 250–500.
Overall, you should expect to pay between CHF 200 and CHF 600 for a thorough diagnostic evaluation, depending on which tests are necessary. However, this investment is worthwhile because it enables targeted treatment and prevents unnecessary or ineffective treatment attempts.
Costs for Treatment and Long-Term Therapy
Treatment costs depend heavily on the underlying cause. For diet-related hair loss, the monthly cost of high-quality food and supplements ranges from CHF 50 to 100. A one-time parasite treatment costs approximately CHF 40–80; in cases of chronic infestation, monthly costs may range from CHF 30 to 60.
For hormonal disorders such as hypothyroidism, lifetime medication costs of CHF 20–40 per month are to be expected; for Cushing’s syndrome, CHF 100–250 per month plus regular blood tests (CHF 80–150 per test, every three to six months). Courses of antibiotics for bacterial skin infections cost approximately CHF 50–120, while antifungal treatments cost CHF 150–350.
In the long term, the costs associated with chronic skin problems can add up to CHF 100–300 per month. In addition, regular veterinary checkups are necessary to monitor the success of treatment and make any necessary adjustments. Dog health insurance may be a good idea in this case, but be sure to check carefully which services are covered, as some insurers provide only limited coverage for skin conditions.
Is dog health insurance worth it?
Dog health insurance can be worthwhile in cases of chronic skin problems or expensive diagnostic tests. Basic insurance plans typically cover only accidents and acute illnesses, while more comprehensive plans also include chronic conditions, diagnostics, and medications. Monthly premiums in Switzerland range from CHF 30 to CHF 120, depending on the scope of coverage, the dog’s breed, and its age.
When signing a contract, pay attention to exclusions and waiting periods. Many insurance policies exclude pre-existing conditions or have waiting periods of three to twelve months for certain benefits. Read the fine print carefully and compare several providers. A good insurance policy covers 80–90% of veterinary costs after deducting the copayment.
Alternatively, you can deposit a fixed amount (e.g., CHF 50–100) into a separate account each month to build up your own “health fund” for your dog. This often works well for healthy dogs, but it doesn’t provide protection against sudden, very expensive illnesses. The decision depends on your financial situation, as well as your dog’s breed and age.
Prevention and Early Detection: How to Prevent Thinning Hair
Optimal Nutrition from the Start
The best way to prevent excessive hair loss starts in the food bowl. From the very beginning, feed your pet a high-quality food with clearly listed ingredients, a balanced nutrient profile, and sufficient essential fatty acids. Make sure that meat or fish is the first ingredient and that the food has an omega-3 to omega-6 ratio of about 1:5 or better.
If necessary, supplement their diet with sources of omega-3, such as flaxseed oil or salmon oil; brewer's yeast for B vitamins and biotin; and high-quality proteins. Avoid frequent changes in their food, as these can strain the digestive tract and lead to nutritional imbalances. If you must change their food, do so gradually over the course of one to two weeks.
Also pay attention to the amount of food you feed your dog; being overweight puts a strain on the metabolism and can lead to skin problems. Being underweight, on the other hand, means a lack of nutrients. Your veterinarian can help you determine the optimal amount of food for your dog. Take the time to choose the right food—it’s the foundation for a healthy, shiny coat and a long, happy life for your dog.
Regular Grooming and Checkups
Regular brushing isn’t just for looks—it’s an active form of preventive health care. By brushing your dog daily or at least twice a week, you remove loose hair before it ends up everywhere, promote blood circulation in the skin, and can detect skin changes early on. While brushing, you should carefully inspect your dog’s skin: Are there any redness, dandruff, scabs, or bald spots?
Use brushing as an opportunity to do a quick “health check”: How does the coat feel—shiny and smooth, or dull and brittle? Does the skin have a neutral odor, or is there an unpleasant smell? Does the dog scratch noticeably during or after brushing? These simple observations will help you identify problems early on, long before they develop into serious illnesses.
Invest in high-quality grooming tools: a good undercoat brush (e.g., Furminator, approx. CHF 30–60), a slicker brush for long-haired breeds (approx. CHF 20–40), and a soft brush for sensitive areas (approx. CHF 15–30). These tools will last for years and are a worthwhile investment in your dog’s coat health. Always brush in the direction of hair growth and avoid applying too much pressure, especially on dogs with sensitive skin.
Semi-annual veterinary checkups
Even if your dog seems healthy, a biannual veterinary checkup is recommended to detect hidden problems early on. During the exam, the veterinarian will check your dog’s skin, coat, ears, teeth, and overall condition and can identify subtle changes that you might miss in everyday life. Regular checkups are especially important for older dogs (age seven and up), as many diseases develop gradually.
During these routine checkups, preventive blood tests can also be performed to detect metabolic disorders, organ problems, or hormonal changes before symptoms become apparent. The cost of a routine checkup is approximately CHF 80–150, with an additional CHF 100–200 for a blood test. While this may seem expensive at first glance, it often prevents far more costly treatments down the line.
Between vet visits, make a note of any unusual observations in a health journal: When was the last time your dog shed? Were there periods of increased shedding? Have there been changes in eating habits, drinking habits, or activity levels? These notes help the vet identify changes over time and make informed diagnoses. Prevention is always less expensive and less stressful than treatment—both for your wallet and for your dog.
Stress Reduction and a Stable Environment
Chronic stress is an underestimated factor in skin and coat problems. Make sure your dog has a regular daily routine, plenty of rest, and mental stimulation. Dogs are creatures of habit; changes in their daily routine, frequent moves, or constantly changing caregivers can trigger stress, which can manifest in their coat over time.
Provide your dog with a quiet place to retreat to where he can sleep undisturbed. Avoid excessive training or overwhelming him; too much physical or mental exertion can also cause stress. Watch for signs of stress such as panting without physical exertion, increased yawning, smacking his lips, or withdrawn behavior.
Adaptogenic herbs such as Withania somnifera (Ashwagandha) can be helpful during periods of stress, but they should never replace a veterinary evaluation if symptoms persist. It is important to identify and eliminate the source of stress, whether through training, behavioral adjustments, or changes in the environment. A stress-free, well-balanced dog has a healthier coat and sheds significantly less than a dog that is constantly stressed.
Affected Dog Breeds: Which Breeds Shed the Most?
Dogs with a double coat
Breeds with a double coat are among the heaviest shedders. The double coat consists of a dense, soft undercoat and a coarser outer coat over it. The undercoat provides insulation, while the outer coat protects against moisture and dirt. In the spring and fall, the undercoat is almost completely shed, resulting in a significant amount of hair.
Among the best-known double-coated breeds are: - Siberian Husky: extremely dense undercoat, sheds heavily twice a year - Alaskan Malamute: similar to the Husky, but with even greater body mass and a larger amount of fur - Samoyed: white, dense coat, sheds moderately year-round and heavily during seasonal shedding - German Shepherd: sheds year-round and particularly heavily during coat changes- Golden Retriever: long outer coat and dense undercoat, large amounts of hair- Labrador Retriever: short but very dense coat, sheds surprisingly heavily- Bernese Mountain Dog: long, dense coat, heavy seasonal shedding- Shiba Inu: compact double coat, shedsextremely heavily twice a yearFrequencyof heavy shedding: Nearly 100% of dogs in these breeds are affected; shedding is concentrated during specific seasons
Short-haired breeds with dense coats
Even short-haired breeds can shed a lot, although the individual hairs are less noticeable. The problem: The short, bristly hairs get deeply embedded in fabrics and are difficult to remove. Typical examples include:
- Beagle: short, dense coat; sheds moderately to heavily year-round— Dalmatian: very short hair that tends to get caught in fabrics— Jack Russell Terrier: wire-haired varieties shed less; smooth-haired varieties shed moderately— Boxer: short coat; sheds moderately but continuously— Weimaraner: short, silky coat; sheds less than othershort-haired breeds. Frequency of heavy shedding: Approximately 60–70% of these breeds exhibit moderate to heavy shedding.
Breeds with Little Hair
Certain breeds shed significantly less or not at all visibly because their hair remains in the coat and does not fall out. These breeds require regular clipping or trimming. Breeds that shed very little include:
- Poodle (all sizes): curly coat, does not shed but does mat— Lagotto Romagnolo: curly, dense coat, sheds very little, must be clipped— Portuguese Water Dog: wavy coat, sheds minimally— Schnauzer: wire-haired coat, must be trimmed regularly— Yorkshire Terrier: silky, long hair, sheds very little, grows continuously— Maltese: long, silky hair without an undercoat, shedsvery littleFrequency of heavy shedding: Less than 10%, but requires more grooming due to shearing/trimming
Genetic Predispositions to Hair Loss
Certain breeds are genetically prone to specific skin problems that can lead to hair loss:
- Husky and Malamute: zinc-responsive dermatosis, requires lifelong zinc supplementation— Doberman: color-mutant alopecia (especially in blue and fawn-colored dogs), incurable— Bull Terrier: hereditary alopecia, usually occurs in young adulthood— Dachshund: Pattern baldness (alopecia on the ears and abdomen), a cosmetic issue with no pathological significance- Chow Chow: Prone to hypothyroidism, which leads to symmetrical hair loss
If you own or are considering getting one of these breeds, learn about the skin problems typical of the breed beforehand and schedule regular veterinary checkups. Understanding their genetic predisposition helps you identify problems early and treat them effectively.
Common Mistakes Dog Owners Make When Their Dogs Shed Heavily
Mistake 1: Bathing too often or incorrectly
One of the most common mistakes is bathing your dog too often, under the assumption that frequent washing reduces shedding. In fact, bathing too often often has the opposite effect: it disrupts the skin’s natural barrier, causing the sebaceous glands to produce fewer protective oils, which leads to dry skin and increased shedding. Dogs should only be bathed when they are truly dirty or when a medicated shampoo has been prescribed; for healthy dogs, bathing every four to eight weeks is perfectly sufficient.
Another mistake is using human shampoos or harsh cleansers. The pH level of a dog’s skin is 7–7.5, while that of human skin is 4.5–5.5. Human shampoos are too acidic for a dog’s skin and destroy its natural protective barrier. Use only mild, pH-neutral dog shampoos or medicated shampoos as recommended by your veterinarian.
Water that’s too hot can also damage the skin. Always bathe your dog with lukewarm water and rinse out the shampoo thoroughly; residue can irritate the skin and cause itching. Then gently dry the coat with a towel, but avoid using a hair dryer on a setting that’s too hot, as this can dry out the skin. When it comes to coat care, less is often more.
Mistake 2: Poor-quality diet and frequent changes in food
Many dog owners underestimate the direct link between diet and coat health. Low-quality food containing grain fillers, meat meal of unknown origin, and an unbalanced nutrient profile leads, over time, to a dull coat, dandruff, and excessive shedding. Don’t cut corners in the wrong place—high-quality food costs more, but it saves on veterinary and grooming costs in the long run.
Frequent changes in diet can strain the digestive tract and lead to nutritional imbalances. Some dog owners switch their dog’s food every month because they believe their dog needs variety. This is a misconception; dogs are creatures of habit, and their digestive systems adapt to a specific diet. Abrupt changes can cause diarrhea, vomiting, and, in the long term, skin problems.
If a diet change is necessary, make the transition gradually over one to two weeks: Start by mixing 25% of the new food with 75% of the old food; after three days, switch to a 50:50 ratio, then 75:25, until the transition is complete. During the transition, watch for changes in stool, skin condition, and behavior. This is the only way the body can adjust without compromising coat quality.
Mistake 3: Ignoring symptoms or treating them yourself
A common mistake is to ignore skin changes or increased hair loss in the hope that the problem will resolve on its own. However, bald spots, redness, scabs, or persistent itching do not go away on their own; they usually get worse over time. The earlier a skin problem is detected and treated, the simpler and more cost-effective the treatment will be.
Another problem is self-medication with over-the-counter products or home remedies without a veterinarian’s diagnosis. What has helped one dog may be ineffective or even harmful to another. Cortisone-based ointments used without a veterinarian’s guidance can cause long-term damage to the skin. Antifungal creams used in human medicine are often too harsh for a dog’s skin and can make the problem worse.
If symptoms persist or worsen, always consult a veterinarian first. Even if the cause turns out to be harmless, you’ll have peace of mind. An early diagnosis often prevents lengthy and expensive treatments. Trust your veterinarian’s expertise and use home remedies or dietary supplements only as a supplement and after consulting with your veterinarian—never as a substitute for a professional diagnosis and treatment.
Frequently Asked Questions
Why is my dog shedding so much?
Excessive shedding can have various causes: Seasonal shedding is completely normal for most dogs twice a year, especially for breeds with a double coat. In addition, nutritional deficiencies (insufficient omega-3 fatty acids, biotin, or zinc), stress, dry air from heating systems, or skin problems such as parasites and allergies can be responsible. Observe whether the shedding is even or if bald spots are developing; the latter indicates a medical problem and should be evaluated by a veterinarian.
How often should you brush a dog that's shedding?
During shedding season, you should brush your dog daily to remove loose hair and stimulate blood circulation in the skin. Outside of shedding seasons, brushing two to three times a week is sufficient for most breeds. Use a high-quality undercoat brush for double-coated breeds and always brush in the direction of hair growth without applying excessive pressure. Regular brushing not only reduces hair in your home but also allows for the early detection of skin changes.
What kind of diet helps promote strong hair in dogs?
High-quality food with clearly labeled meat as the main ingredient, a balanced omega-3 to omega-6 ratio (approximately 1:5), and sufficient micronutrients forms the basis. Supplement the diet with sources of omega-3 such as salmon oil or flaxseed oil, brewer’s yeast for B vitamins and biotin, and zinc as needed. Initial improvements usually become apparent after four to six weeks of consistent feeding. If problems persist, veterinary nutritional counseling is recommended to specifically address any nutritional deficiencies.
When should I take my dog to the vet for hair loss?
A visit to the veterinarian is necessary if your dog has bald spots that do not regrow hair, symmetrical hair loss on the flanks or abdomen, red or scaly skin, intense itching, or if your dog is constantly licking the same areas. You should seek emergency care if your dog has open, weeping wounds; circular bald patches with scaly edges (possibly a fungal infection); or if hair loss is accompanied by a fever, loss of appetite, or unusual drinking behavior. The sooner you act, the easier and more cost-effective the treatment will be.
Can excessive hair loss in dogs be treated?
Yes, in most cases, excessive hair loss can be treated. Diet-related causes can be significantly improved within six to eight weeks by changing the diet and using targeted dietary supplements. Parasitic and bacterial skin problems can be cured with consistent treatment. Although hormonal disorders such as hypothyroidism are not curable, they can be well controlled with lifelong medication, and hair loss usually subsides after three to six months. Only genetically caused forms, such as color mutant alopecia, cannot be treated.
Which brush is best for dogs that shed a lot?
For dogs with a double coat, an undercoat brush such as the Furminator (CHF 30–60) is ideal, as it specifically removes loose undercoat without damaging the topcoat. In addition, a slicker brush is recommended for long-haired breeds, and a soft natural-bristle brush for sensitive areas. Avoid wire brushes that are too harsh, as they can irritate the skin. Invest in high-quality tools—they’ll last for years and be gentle on your dog’s skin and coat during daily grooming.
How much does treatment for excessive hair growth cost in Switzerland?
Costs vary considerably depending on the cause: An initial veterinary examination costs CHF 80–150, and diagnostic tests (skin scraping, blood count, fungal culture) range from CHF 200 to CHF 600. Optimizing your dog’s diet with high-quality food and supplements costs CHF 30–80 per month. Medication for hormonal disorders costs CHF 20–250 per month. For chronic skin problems, you should expect to pay CHF 100–300 per month over the long term. Pet health insurance may cover some of these costs.
