Healthy skin and a shiny coat that looks and feels its best starts with diet. The best food for your pet’s skin and coat health is a complete and balanced food suited to your pet’s species, life stage and individual needs, and is something they enjoy, tolerate well and that works for your routine and budget. Keep treats, toppers and supplements in balance with their overall diet, support them with a suitable grooming routine, and check in with your vet when something isn’t quite right.

Your pet’s skin and coat can tell you plenty about what’s happening beneath the surface. A healthy-looking coat can be one sign they’re getting the care and nutrition they need. But dryness, dullness, excessive shedding, bald patches or persistent itching can have many causes, and food isn’t always the answer.
There isn’t one “best” food for every pet. A complete and balanced diet suited to their individual needs provides a strong nutritional foundation for healthy skin and coat. Read on to learn which nutrients matter, what to look for in their food and when a change deserves a chat with your vet.
Why does skin and coat health matter?
Skin may not get as much attention as a glossy coat, but it’s your pet’s largest organ and it has a big job to do.
Healthy skin acts as the body’s first line of defence, helping protect your pet from environmental irritants and potentially harmful microorganisms while limiting water loss. When this protective barrier is weakened, the skin can become dry, itchy or inflamed and more vulnerable to secondary infections.
Their coat earns its keep too. Beyond looking lovely, it provides another layer of protection and helps regulate body temperature.
What can affect your pet’s skin and coat health?
Changes in your pet’s skin or coat can have many causes, so it’s important not to assume their food is automatically to blame. Possible factors include:
- Parasites such as fleas, mites or lice
- Allergies, including environmental and food allergies
- Hormonal conditions or other underlying illnesses
- Inadequate nutrition or an imbalanced diet
- Digestive conditions that affect nutrient absorption
- Contact with irritating plants, chemicals or grooming products
- Grooming issues, including matting or excessive grooming
Whatever the original cause, scratching and inflammation can weaken the skin barrier. This may allow bacteria or yeast that normally live on the skin to multiply more easily, sometimes leading to a secondary infection.
Signs your pet may have a skin or coat concern
Skin and coat concerns can look similar even when their causes are very different. Speak with your vet before assuming food is the answer if you notice:
- Persistent itching, chewing, licking or overgrooming
- Unusual hair loss, from general thinning to bald patches
- Red, inflamed or thickened skin
- Dry, flaky or scaly skin
- Scabs, sores or unexplained wounds
- An unusual or unpleasant odour
- Oily or greasy skin and fur
- Discharge from skin or ears
- Recurrent ear infections
- A sudden change in the condition of their skin or coat
Your vet can help identify the cause and recommend the right next step, which may or may not include a dietary change.
How does nutrition support skin and coat health?
Nutrition is only one part of the skin-and-coat picture, but it’s an important one. Your pet’s body needs a steady supply of protein, fats, vitamins, minerals and energy to produce and maintain skin cells and hair follicles.
If they don’t receive enough of an essential nutrient – or a health condition interferes with digestion or nutrient absorption – changes may show up in their skin or coat.
The whole diet matters
Don’t judge a food by one impressive-sounding ingredient – the whole nutritional formulation matters. The ingredient list tells you what went into a food, but it doesn’t tell the full story about the nutritional balance, digestibility or availability of key nutrients in the finished diet.
For most healthy pets, feeding an appropriate amount of complete and balanced food suited to their species, life stage and individual needs will provide the essential nutrients they need.
More isn’t always better. Adding extra vitamins, minerals or oils isn’t necessarily a shortcut to a shinier coat. Some nutrients can be harmful in excessive amounts, while supplements may disrupt the balance of an otherwise complete diet. Speak to your vet before adding supplements, particularly if your pet has an existing health condition or is eating a therapeutic diet.
Which nutrients support healthy skin and coat?
A range of nutrients work together to support your pet’s skin and coat health:
| Nutrient | Why it matters for skin & coat health |
| Amino Acids | Building blocks for the proteins needed for building skin cells and the keratin that forms hair. |
| Omega-3 fatty acids | Can have an anti-inflammatory effect in the skin and elsewhere in the body. |
| Omega-6 fatty acids | Help maintain the skin’s protective barrier. |
| Vitamin A | Supports normal skin-cell growth, turnover and repair. |
| B vitamins, including biotin | Support processes involved in maintaining healthy skin and hair. |
| Vitamin E and selenium | Work together as part of the body’s antioxidant defences. |
| Zinc | Supports skin-barrier function, cell renewal and healthy hair growth. |
| Copper | Supports normal skin and hair structure and contributes to coat pigmentation. |
These nutrients also have important jobs throughout the body, and they work best as part of a well-formulated diet. The right amounts, balance and digestibility all matter, which is why the complete diet is more important than any single ingredient or front-of-pack claim.
What’s the best food for healthy skin and a shiny coat?
There isn’t one “best” food for every pet. For most dogs and cats, the right starting point is a complete and balanced food suited to their species, life stage, size and individual needs. It should also be something they enjoy, tolerate well and can eat consistently.
A complete and balanced food provides the essential nutrients your pet needs for overall health, including healthy skin and coat. If your pet is otherwise healthy but their coat quality is a particular concern, you may choose a complete and balanced diet specifically formulated to support skin and coat health.
If your pet has an underlying health issue, your vet may recommend a specific diet as part of their management plan.
Food is only one part of supporting your pet’s skin and coat health
Nutrition gives your pet’s skin and coat the building blocks they need, but it can’t brush out a knot or diagnose an allergy. A complete and balanced diet works best as part of the bigger picture, alongside a suitable grooming routine and veterinary care when something doesn’t look or feel right.
When to see your vet about skin and coat changes
Different skin conditions can look surprisingly similar, so changing your pet’s food based on guesswork may delay the right diagnosis and treatment. If an allergy, parasite, infection or another health condition is involved, the right next step will depend on the cause—and may or may not include a dietary change.
If you notice a change in your pet’s skin or coat, book a visit with your vet. They can investigate the cause, rule out underlying health concerns and recommend the right treatment or nutritional support.
Grooming matters too
Regular grooming helps keep your pet’s coat in good condition by removing loose hair, preventing mats and distributing natural oils throughout the coat.
How often your pet needs brushing and bathing depends on their coat type. Long, curly or thick double coats may need more frequent brushing or professional grooming, but short-haired pets benefit from regular coat care too.
