Coat care for dogs: how nutrition supports healthy skin

Omega-3 fatty acids, zinc and B vitamins are proven helpers that can already be contained in the right choice of food, and that is exactly where they can do the most good. Your dog does not need to be burdened with complicated measures. A shiny, strong coat is not just a question of looks, but a reliable sign that your dog is doing well all round.

Which nutrients your dog actually needs, how you can recognise nutritional deficiencies and how to sensibly combine coat care with the right feeding is shown in the following sections, tailored to your dog's needs throughout the year.⏱️ Reading time: approx. 25 minutes

Quick overview: coat care and nutrition at a glance

Coat care in dogs starts in the food bowl

Why nutrition is the key to a healthy coat

Skin and coat are not purely external features; they are a direct reflection of what is going on inside your dog's body. If the coat looks dull, more dandruff appears or your dog scratches frequently, the cause usually lies deeper: in the supply of nutrients. External care such as brushing or bathing can improve the appearance in the short term, but without the right building blocks from within, the effect remains superficial.

The biological pathway is easy to follow: nutrients from food are absorbed in the gut, travel via the blood to the hair follicles and supply the cells there that form new hair. If essential fatty acids, trace elements or vitamins are missing at this point, coat quality noticeably suffers. A deficiency does not only show after months; it can leave visible traces within a few weeks.

A concrete example: a Golden Retriever with a dull coat and visible dandruff can shine again within 4–6 weeks of a targeted change of diet, without any additional bathing or expensive care shampoos. The first visible improvements often appear after just 3–4 weeks, and full stabilisation of the coat is realistic after 8–12 weeks. This gives you as an owner a clear time window in which to observe and assess changes.

External coat care has its place: regular brushing stimulates blood flow to the skin and removes dead hair. But it works like a clean façade: without a solid foundation, it does not last long. If you want to make a lasting change, you have to start with the food, and that is ultimately also the more cost-effective solution.

Coat care and the right diet: the basics check

Ask yourself honestly: what is in your dog's bowl today? Many owners reach for the same food for years without questioning whether it really covers their dog's specific needs. Pet food is often well marketed, but rarely transparent when it comes to nutrient profiles.

Deficiencies often creep in before symptoms become truly noticeable. Is your dog scratching a little more than before? Is the coat losing its shine even though you brush regularly? Does dandruff keep reappearing after bathing? These are early signs that are often ignored until the picture becomes clearer and the problem more persistent. If you look closely early on, you will spare yourself more elaborate measures later. If you also suspect that malnutrition in dogs could be behind the symptoms, you should review the diet systematically.

With certain breeds in particular, a closer look is worthwhile: because of their dense double coat, German Shepherds and Border Collies have up to 1.5 times the requirement for skin-supporting nutrients compared with short-haired breeds. If this is not taken into account, there is a risk of a suboptimal supply despite high-quality food. Small adjustments can have a big effect, for example the daily addition of 10 ml of salmon oil, which costs just 20–30 CHF a month and brings visible changes within a few weeks in many dogs.

How does nutrition support coat care in dogs?

Hair consists of more than 90 % protein, which makes protein the most important building block for strong, elastic hair. For adult dogs, a protein content of at least 18–22 % in the food is recommended, and for puppies in the growth phase as much as 22–32 %. If the content is lower or inferior protein sources are used, the body responds by using the available protein primarily for vital organs, and skin and coat literally miss out.

Fats play an equally central role: they activate the sebaceous glands in the skin and provide the natural protective film that shields the coat from drying out, external influences and infections. Without this film, the skin becomes cracked and susceptible to inflammation. Unsaturated fatty acids in particular, for example from linseed oil or oily fish, support the skin's barrier function at cellular level.

Trace elements and vitamins work in the background, but no less effectively. Zinc regulates cell division in the hair follicles, biotin strengthens the hair structure and vitamin E protects skin cells from oxidative stress. A Boxer, for example, whose food is supplemented daily with 15 ml of linseed oil, costing around 25 CHF a month, usually shows less scratching, softer skin and a more even coat after about six weeks. These results are not the exception, but what a consistent supply of nutrients can achieve.

This makes it clear: the right diet is not an add-on to coat care, it is its foundation. Which nutrients are decisive and in what amounts they work is shown in the next section.

The most important nutrients for healthy skin and coat

Omega-3 fatty acids: the star of coat health

Omega-3 fatty acids are among the most effective nutrients for the health of skin and coat. Their main task is to counter inflammation at the skin barrier: they reduce local inflammatory reactions that lead to itching, redness and dandruff, and at the same time help to retain moisture in the skin. A dog with an adequate supply of omega-3 has supple, elastic skin and a coat that still shines even after drying.

The best natural sources are oily sea fish such as salmon and mackerel, cold-pressed linseed oil, algae and walnuts. A rule of thumb applies to dosage: 50–100 mg of omega-3 per kilogram of body weight daily. A dog weighing 20 kilograms therefore needs between 1,000 and 2,000 mg daily, an amount that can easily be reached through high-quality oils or suitable supplements. When buying fish oil or linseed oil, you should look for oxidation-resistant packaging and store the product in a cool place after opening. The bottle should be used up within six months at the latest, as omega-3 fatty acids go rancid and then lose their benefit.

Many dog owners invest in expensive care products or frequent visits to the vet without knowing that targeted dietary adjustments are often the most effective and cost-efficient measure. Especially in Switzerland, where sustainable practices and regional quality play an important role, it is worth looking at feed products with clearly defined nutrient profiles. Natural sources such as linseed and lignans provide plant-based omega-3 fatty acids and support the skin from within, without synthetic additives. Such supplements should be seen as a sensible accompaniment to veterinary advice, but do not replace it.

Deficiency symptoms often develop gradually: at first the coat looks dry and dull, then dandruff and increased scratching follow. With a longer-lasting deficiency, inflammation develops that keeps recurring without any recognisable external cause. If you know these signs, you can counteract them early and thus prevent greater effort.

Zinc and B vitamins: underestimated helpers

Zinc is one of the most frequently underestimated minerals when it comes to coat health. It controls cell division in the hair follicles, supports wound healing in the skin and is a key factor in the immune system. Zinc deficiency in dogs typically shows as brittle, lacklustre hair, hair loss in clumps and rough, flaky skin, especially around the eyes, mouth and paws. Certain breeds such as Siberian Huskies or Alaskan Malamutes have a genetically higher zinc requirement and are particularly sensitive to an undersupply.

B vitamins form a category of quiet helpers of their own: biotin strengthens the hair structure and is essential for keratin synthesis, niacin regulates fat metabolism in the skin and pantothenic acid supports the regeneration of the hair follicles. A deficiency in these vitamins initially leads to non-specific symptoms, slightly more dandruff, a slightly duller coat, before the picture becomes clearer. Natural sources of B vitamins are beef, chicken offal such as liver, wholegrain cereals and pulses. Hydrolysed yeast and brewer's yeast also provide B vitamins naturally and can easily be added to the daily food.

If you are considering targeted supplementation alongside veterinary advice, you should opt for products with transparent nutrient information and always keep the overall supply in mind. An oversupply of zinc can be just as problematic as a deficiency, so the rule is: follow dosage recommendations and ask your vet if in doubt. Especially if there are also signs of food intolerance in dogs, a professional assessment makes sense, because itching and flaking can also point to an overreaction of the immune system, not just a nutrient deficiency.

A basic supply of high-quality proteins, omega-3 fatty acids, zinc and B vitamins sets the decisive course for healthy skin and a shiny coat. How these findings can be put into practice in everyday life, without great effort or high costs, is shown in the next section.

Putting it into practice in everyday life

How many nutrients does my dog really need?

The optimal nutrient supply depends on several factors: your dog's size, weight, breed, age and activity level all play a central role. An active Border Collie weighing 20 kilograms has a significantly higher energy requirement than an older Pug of the same weight who mainly rests on the sofa. If you want to tailor your dog's basic nutrition to coat care, you should know these differences and take them into account when planning meals.

As a guide for proteins: adult dogs need at least 18–22 % protein in their food, puppies in the growth phase 22–32 %, and pregnant or lactating bitches up to 28 %. Fats should be between 10–15 % for adult dogs; for active dogs or in winter it can also be 15–20 %. Zinc is recommended at a daily dose of about 1 mg per kilogram of body weight, biotin at 2–5 µg per kilogram, and omega-3 fatty acids, as already mentioned, at 50–100 mg per kilogram.

These values are guidelines that should be adjusted to individual needs. If in doubt, a vet can carry out a blood test to identify possible deficiencies. Special circumstances such as pregnancy, illness or convalescence also require an adjusted nutrient intake, which may be well above the standard recommendations.

If you follow these values and choose high-quality food with transparent nutrient information, you lay the best foundation for a healthy coat and vital skin. The cost of this is often in the range of 50–150 CHF a month, depending on the size of the dog and the supplements chosen, an investment that pays off in the long term through fewer visits to the vet and less grooming effort.

Changing food: how to make the switch without stress

A change of food should always be made gradually, to avoid digestive problems and to give the body time to adjust to new nutrients. A period of 7–10 days is recommended, during which the new food is gradually mixed with the old. Start with 25 % new food on the first day, increase to 50 % on the third day and 75 % on the fifth day, and feed only the new food from the eighth day.

During the transition, you should watch closely how your dog reacts: are his stools still normal? Does he show signs of intolerance such as diarrhoea, vomiting or increased scratching? If so, slow down the transition and give the body more time. If problems persist, you should consult a vet to make sure there is no food allergy or intolerance.

In addition to a high-quality basic food, targeted supplements can be useful: a tablespoon of salmon oil daily, some brewer's yeast mixed into the food or a pinch of zinc as a supplement can visibly improve the coat. It is important to follow the dosages and not to give several preparations at the same time without veterinary advice, to avoid an oversupply.

Patience is needed especially with dogs that already have coat problems: visible improvements do not happen overnight, but usually after 4–8 weeks of a consistent change of diet. If you stick with it, you will be rewarded with a healthy, shiny coat that radiates from the inside out.

Making use of regional food options in Switzerland

Swiss pet food manufacturers often offer high-quality, sustainably produced products tailored to the needs of dogs in temperate climates. Regional suppliers frequently rely on transparent lists of components, short transport routes and controlled quality standards, factors that benefit not only the environment but also your dog's health.

If you are looking for food specifically aimed at coat and skin health, look for products with a high proportion of omega-3 fatty acids, zinc and B vitamins. Many Swiss manufacturers now offer special food for dogs with skin problems that contains precisely these nutrients in higher concentrations. Such products are usually somewhat more expensive than standard food, but save costs for vet visits and care products in the long run.

Natural supplements such as linseed, herbal blends and brewer's yeast can further enrich the diet and are often available in regional pet shops or online from specialist suppliers. If you opt for such products, you should make sure they serve as a supplement to a balanced basic diet and are not seen as the sole solution. Veterinary advice is always sensible if you are unsure or if your dog already has health problems.

Seasonal adjustments for a healthy coat

Coat care in winter: which nutrients matter now

Winter places special demands on your dog's coat health. Dry heating air, cold and less sunlight put additional strain on skin and coat. The skin loses moisture more quickly, the coat becomes brittle and many dogs develop more dandruff. At the same time, the body needs more energy to maintain its body temperature, which increases the overall nutrient requirement.

At this time, omega-3 fatty acids are particularly important: they support the skin barrier and help to retain moisture in the skin cells. A daily supplement of salmon oil or linseed oil at a dose of 10–15 ml for a medium-sized dog can bring visible improvements after just two to three weeks. Vitamin E as an antioxidant is also indispensable in winter, as it protects skin cells from oxidative stress and supports regeneration.

Zinc also plays a central role, as it promotes wound healing and strengthens the immune system, especially in the cold season when infections are more common. Many dog owners forget that paws also need special care in winter: road salt and grit irritate the skin and can lead to cracks and inflammation. A nutrient-rich diet supports healing from within, while external care such as washing the paws after a walk also helps.

If you slightly increase the amount of food in winter and focus on skin-supporting nutrients, you give your dog the best conditions to get through the cold season in good health. The additional cost of high-quality oils or supplements is around 20–40 CHF a month, a manageable amount that pays off in the form of fewer visits to the vet and a vital, shiny coat.

Coat care in summer: protection from heat and UV radiation

In summer, coat care faces different challenges: heat, UV radiation and more frequent bathing can put a strain on skin and coat. Dogs with light-coloured or thin coats are particularly at risk of sunburn, which is not only painful but can also cause long-term skin damage. At the same time, the body loses more fluid through panting, which dries out the skin even further.

At this time, antioxidants such as vitamin E and vitamin C are particularly important, as they protect skin cells from UV damage and promote regeneration. Beta-carotene, found in carrots and pumpkin, also supports skin health and can strengthen the body's natural UV defences. Omega-3 fatty acids remain indispensable in summer too, as they have an anti-inflammatory effect and stabilise the skin barrier.

Many dog owners bathe their dog more often in summer, to cool it down or to clean it after swimming in a lake. Care should be taken to use mild, pH-neutral shampoos that do not attack the skin's natural protective layer. Bathing too often can dry out the skin and encourage itching; once a month is usually enough, unless the dog has got very dirty.

In addition to the right diet, dog owners should make sure in summer not to walk their dog in the blazing midday sun and to choose shady spots for rest breaks. An adequate water supply is essential to maintain fluid balance and to nourish the skin from within. If you combine these measures with a nutrient-rich diet, you will protect your dog in the best possible way from the strains of summer.

Supporting shedding: spring and autumn

Twice a year, in spring and autumn, most dogs go through an intensive period of shedding. The undercoat is shed to adapt the coat to the season. This process is energy-intensive and places high demands on the body's nutrient supply. If you specifically adjust your dog's diet for coat care during this time, you can speed up shedding and noticeably improve your dog's well-being.

Proteins are particularly important in this phase, as hair consists of more than 90 % keratin, a structural protein built from amino acids. An increased protein content in the food of 22–25 % can support shedding and ensure that the new coat grows back strong and shiny. Biotin and zinc also play a central role, as they promote cell division in the hair follicles and strengthen the hair structure.

Omega-3 fatty acids help to reduce inflammation that can arise from the intensive metabolism during shedding. Many dogs show increased scratching or restlessness during this time, a sign that the skin is irritated. A daily supplement of 10–15 ml of salmon oil or linseed oil can noticeably ease these symptoms and make shedding more comfortable.

Regular brushing is indispensable during shedding: it removes dead hair, stimulates blood flow to the skin and supports the growth of the new coat. Depending on the breed, brushing should be done daily or every other day, especially for long-haired breeds such as Golden Retrievers or German Shepherds. If you combine this external care with a nutrient-rich diet, you give your dog the best support during this demanding phase.

Common mistakes in coat care through nutrition

Overdosing on supplements

Supplements can be useful support if they are used in a targeted way and at the right dosage. However, many dog owners tend to give several preparations at the same time without checking the overall supply. The result is often an oversupply, which can be just as problematic as a deficiency.

With fat-soluble vitamins such as vitamins A, D, E and K in particular, there is a risk of hypervitaminosis, as the body does not simply excrete excess amounts but stores them. An overdose of vitamin A can lead to joint problems, loss of appetite and liver damage; too much vitamin D can put a strain on the kidneys. An oversupply of zinc is also problematic: it can inhibit the absorption of copper and iron and lead to anaemia and a weakened immune system.

If you want to use supplements, you should first carry out a thorough needs analysis, ideally in consultation with a vet. Blood tests can show whether there really is a deficiency and to what extent supplementation is needed. The composition of the basic food must also be taken into account: high-quality foods already contain many of the necessary nutrients in sufficient quantities, so additional preparations are often unnecessary.

The motto is: less is more. A targeted, moderate supplement is always better than the ill-considered use of several products at once. If you are unsure, you should seek professional advice so that you help your dog more than you harm him in the long run.

Low-quality food as a false economy

Not all food is the same, and price is often an indicator of quality. Low-quality food frequently contains inferior protein sources such as animal meal or plant by-products, which increase the official protein content but are biologically poorly utilised. The fat content is also often covered by cheap, highly processed oils that contain hardly any essential fatty acids and can go rancid.

If you save in the wrong place, you end up paying more: dogs that are fed low-quality food over a long period often have a dull, brittle coat, skin problems, increased scratching and a higher susceptibility to infections. The follow-up costs for vet visits, care products and medication quickly exceed the money saved on food. High-quality food may seem more expensive at first glance, but saves money in the long term and ensures a healthy, vital life for your dog.

When buying food, you should look for transparent lists of components: is a specific meat source such as "chicken", "beef" or "salmon" listed first? Are the fat sources clearly named, such as "salmon oil" or "linseed oil"? Does the food contain artificial colourings, flavourings or preservatives? If so, caution is advised. High-quality foods do without these additives and rely on natural, easily digestible components.

It is also worth looking at the nutrient profile: a good food should contain at least 18–22 % protein and 10–15 % fat, and the most important trace elements and vitamins should be present in sufficient quantities. If you take the time to compare foods and switch if necessary, you are investing in your dog's long-term health.

Neglecting individual needs

Every dog is different, and what works for one does not necessarily suit another. Breed, age, activity level, state of health and even individual preferences play a role in choosing the optimal food. If you feed in a one-size-fits-all way without considering your dog's specific needs, you risk an undersupply or oversupply.

A young, active Border Collie has a significantly higher energy requirement than an older, easy-going Pug. A Siberian Husky with a genetically higher zinc requirement needs different supplementation from a Labrador with a normal zinc supply. Pregnant or lactating bitches have an increased need for proteins, calcium and energy, while overweight dogs need a calorie-reduced but nutrient-rich diet.

If you recognise your dog's individual needs and adjust the diet accordingly, you lay the foundation for long-term health and well-being. Professional nutritional advice from a vet or a specialist nutrition adviser can help to develop the optimal feeding strategy. The investment in such advice pays off in the long term, through fewer health problems, lower vet costs and a happier, more vital dog.

When should I see the vet?

Recognising warning signs: when coat problems are more than just a grooming issue

Not every coat problem can be solved by adjusting the diet. There are warning signs that point to serious health problems and require immediate veterinary investigation. If you know these signs and act early, you can avoid serious consequences and spare your dog unnecessary suffering.You should go to the vet immediately if:

- Your dog suddenly loses a lot of hair, especially if bald patches appear- The skin is red, swollen or inflamed and has weeping wounds- There is severe, persistent itching that leads to self-injury through scratching- Your dog seems apathetic, refuses food or has a fever- Dandruff suddenly appears in large quantities, accompanied by an unpleasant smell- Changes in behaviour such as aggression, restlessness or social withdrawal occur

These symptoms can point to skin infections, parasites, hormonal disorders, allergies or systemic diseases that require specific medical treatment. A change of food alone is not enough in these cases, and delayed treatment can make the condition worse.

A visit to the vet also makes sense if coat problems persist for more than 8–12 weeks despite targeted dietary adjustments. There may be an underlying condition that needs to be treated first before the diet can take full effect. The vet can identify the exact cause through blood tests, skin swabs or allergy tests and initiate targeted therapy.

Diagnostics: what the vet should check

If you take your dog to the vet because of coat problems, thorough diagnostics should be carried out to determine the exact cause. A visual diagnosis alone is often not enough, as many coat problems show similar symptoms but have different causes.

Standard examinations include:

- Skin swab: detection of bacteria, fungi or yeasts on the skin- Parasite check: detection of fleas, mites or lice infestation- Blood test: checking for nutrient deficiencies, organ values and hormone status- Allergy test: identification of food or environmental allergies- Skin biopsy: in persistent or unclear cases, for an exact diagnosis

Comprehensive diagnostics in Switzerland cost between 200 and 600 CHF depending on the scope, but are a worthwhile investment, as they enable targeted action and avoid lengthy trial-and-error treatment. Once the cause is clear, the therapy can be adjusted precisely, saving time, money and unnecessary suffering for the dog.

After the diagnosis, an individual treatment plan should be drawn up together with the vet, covering both medical measures and dietary adjustments. Close cooperation between owner and vet is the key to lasting success.

Costs and benefits: why prevention pays off

Prevention is the best and most cost-effective strategy for avoiding coat problems. If you rely on a high-quality, nutrient-rich diet from the outset and take your dog's individual needs into account, you will save considerable costs for vet visits, medication and complex treatments in the long term.

An example calculation: high-quality food with targeted supplements such as salmon oil costs around 80–150 CHF a month, depending on the size of the dog. Treating a chronic skin condition, on the other hand, can quickly cost 500–1,500 CHF, including diagnostics, medication and follow-up appointments. If you invest preventively, you will therefore pay significantly less in the long term and spare your dog unnecessary strain.

Time is also a factor: regular vet visits, administering medication and elaborate care measures cost time and nerves. A well-balanced diet, on the other hand, requires a careful choice once, but then largely runs by itself. The daily effort is limited to measuring out supplements and regularly observing your dog, measures that can easily be integrated into everyday life.

Prevention also means reacting early to warning signs. If you review and, if necessary, adjust the diet at the first signs of a dull coat or increased scratching, you can often prevent bigger problems. Investing in knowledge about the right coat care and nutrition pays off in the form of a healthy, happy dog, and that is priceless.

A healthy coat through the right diet, long-term and sustainable

A healthy coat does not develop on the surface; it grows out of a well-nourished body. If you specifically supplement your dog's diet with high-quality proteins, omega-3 fatty acids, zinc and B vitamins, you create the basis for a shiny, strong coat. Visible improvements often appear after just 4–6 weeks, and a stable change is realistic after 8–12 weeks.

Small, targeted adjustments, such as adding salmon oil or linseed oil daily, are inexpensive and more effective than many expensive care products. With long-haired breeds in particular, it is worth taking a close look at the nutrient supply. If your dog scratches more, has a dull coat or shows dandruff, that is a sign to act. A vet can help you find the right feeding and rule out any deficiencies.

With this conscious approach, you give your dog the best conditions for a healthy, beautiful coat, entirely from the inside out. Investing in a high-quality diet and targeted supplements not only pays off in the form of a shiny coat, but also contributes to your dog's overall health and quality of life. Coat care begins in the food bowl, and once you have taken that on board, you have already taken the most important step.

Frequently asked questions

Which nutrients promote a healthy dog coat?

Omega-3 fatty acids from salmon or linseed oil have an anti-inflammatory effect and retain moisture in the skin. Zinc controls cell division in the hair follicles and is essential for hair structure. High-quality proteins (at least 18–22 % in the food) form the basis for a strong coat, as hair consists of more than 90 % keratin. B vitamins such as biotin and niacin support keratin synthesis and regulate the skin's fat metabolism. If coat problems persist, you should consult a vet so that deficiencies can be diagnosed specifically.

How often should a dog be brushed?

Long-haired breeds such as Golden Retrievers or German Shepherds need daily brushing, especially during shedding in spring and autumn. For short-haired breeds such as Labradors or Boxers, 2–3 times a week is enough. Regular brushing removes dead hair, stimulates blood flow to the skin and distributes the natural skin oils evenly through the coat. During shedding, daily brushing can noticeably shorten the phase and reduce itching. External care alone is not enough, however: without a balanced diet, the effect remains superficial.

Can diet reduce hair loss in dogs?

Yes, if the hair loss is diet-related. Deficiencies in omega-3 fatty acids, zinc, biotin or high-quality proteins often lead to increased hair loss and a dull coat. With diet-related hair loss, a targeted change of food shows visible improvements within 4–8 weeks. Important: sudden, heavy hair loss with bald patches requires immediate veterinary investigation, as hormonal disorders, parasites or skin infections can also be the cause. The vet can identify the exact cause through blood tests and initiate targeted therapy.

Which oils are good for coat care in dogs?

Salmon oil and linseed oil are particularly recommended, as they are rich in omega-3 fatty acids. The dosage is 50–100 mg of omega-3 per kilogram of body weight daily; for a dog weighing 20 kg, this corresponds to about 10–15 ml of oil. Salmon oil contains EPA and DHA, while linseed oil provides plant-based alpha-linolenic acid. Both oils should be cold-pressed, stored in dark bottles and used up within six months of opening. The monthly cost is 20–30 CHF. The first improvements usually appear after 3–4 weeks of regular use.

How can I recognise diet-related coat problems in my dog?

Typical signs are a dull, lacklustre coat, increased dandruff, dry or greasy skin, increased scratching without any visible parasites, as well as brittle hair and hair loss in clumps. The symptoms develop gradually over weeks. The areas around the eyes, mouth and paws are often particularly affected. In long-haired breeds, nutrient deficiency shows sooner than in short-haired breeds. If these symptoms persist despite regular grooming, you should review the diet and, if necessary, consult a vet. Blood tests can reveal specific deficiencies.

What does changing food for a better coat cost in Switzerland?

High-quality basic food costs 50–100 CHF a month, depending on the size of the dog. Targeted supplements such as salmon oil (20–30 CHF/month) or zinc preparations (15–25 CHF/month) come on top. Overall, the investment is 50–150 CHF a month. A one-off veterinary nutrition consultation costs 80–150 CHF, but saves treatment costs in the long run. For comparison: treating chronic skin problems can cost 500–1,500 CHF. Investing preventively in a high-quality diet is significantly cheaper than later treating diet-related coat problems.

How long does it take for a change of diet to work?

With a consistent change of food, the first visible improvements appear after 3–4 weeks: the coat becomes softer and shinier. After 4–8 weeks, itching noticeably decreases, dandruff recedes and the skin becomes more supple. Full stabilisation of the coat is realistic after 8–12 weeks. With persistent problems, it can also take 3 months. Patience and consistency are important: hair growth cycles last several weeks, so changes show with a delay. If there is no improvement after 12 weeks, a vet should rule out other causes.
