Many factors influence the overall health of your dog’s skin and coat: His diet and grooming schedule, the presence of parasites and seasonal changes can all play a role. Whether your dog is prone to skin issues or you want to ensure your pup’s health for years to come, you’ll need to keep a few key things in mind.
Regular veterinary checkups will ensure that your dog is disease- and parasite-free. Flea-bite allergy and external parasites, such as mange, are primary causes of hair loss and skin problems.
In addition to scheduling checkups, check your dog’s hair and skin at least once a week for signs of fleas (flea dirt or bites), mange or other skin conditions, and hair loss.
If your dog’s skin seems thick or scaly or lacks elasticity, or if you notice hair loss, these signs might indicate a nutritional deficiency. Check with your veterinarian, and try feeding him a premium food. It will usually take between six and eight weeks after a diet change to see results. If your pet continues to scratch and chew his skin, consult a veterinarian.
When looking for a dog food that will promote good skin and coat health, keep the following in mind:
What's the best thing you can do for your dog’s skin and coat health? Feed a high-quality food packed with protein, such as IAMS™ ProActive Health™ Adult MiniChunks. Dogs are best fed as carnivores: They need protein and thrive on diets rich in animal-based protein sources. Additionally, their hair is actually 95% protein! Although coat growth varies by breed, the combined growth of all the hair can add up to 100 feet per day in some dogs. This means that nearly 30% of the animal’s daily protein requirement is used just for coat growth during some seasons.
Premium pet foods are carefully formulated to be complete and balanced, which means the food includes all of the nutrients your pet needs. Ingredients in premium foods are highly digestible so your dog's body uses the nutrients efficiently. Less costly foods might contain lower-quality proteins. Though a bag of premium food may cost a bit more than other brands, you might be able to feed less, which minimizes the cost difference.
It’s easy to spot a healthy-looking dog: He has a gleam in his eye, a bounce in his step and a glossy, healthy coat. That glow is a reflection of your dog’s overall health and a good gauge of what’s going on inside and outside.
Regular grooming helps take care of the “outside” by removing loose hair, dirt and mats, and distributing skin oils. Grooming lets you check your pet closely, catching any skin problems early. Plus, your dog will love the attention!
As dogs age, their skin might become more sensitive. Select a mild dog shampoo for your older dog. Shampoos made from coconut or palm oils are the mildest. Unusual or “doggy” odors can signal disease, so if odors persist, contact your veterinarian. Do not use human shampoos because they are often too harsh for a dog’s skin.
When bathing your dog, be sure to rinse him thoroughly. Residue left on the skin can be irritating. You might want to follow the shampoo with a hair conditioner to control static electricity and add extra body or sheen.
During the summer, pay close attention to your dog’s skin and coat. Many dogs shed a winter coat and others face flea problems, so it’s a good time to evaluate your dog’s skin and coat condition to nip any problems in the bud.
Attention to your dog's coat and skin from the inside out will produce a healthy, lively dog that is a joy to look at — and a pleasure to live with — every day!


Nutrients like protein, fat, vitamins and minerals are vital to the skin and coat health of dogs. Your dog’s coat is made up almost entirely of protein. If his diet doesn’t contain enough protein quantity and quality, hair might fall out or become dry, weak and brittle. Likewise, his skin is made up of tightly packed flat cells with tough membranes made of proteins and fats. Without proper amounts of these nutrients, the cell membranes weaken, allowing water to escape and bacteria and viruses to enter more easily.
Make sure your dog is getting the following nutrients to keep his coat and skin healthy.
Proteins are found in both animal-based and plant-based ingredients. However, animal-based proteins contain all the essential amino acids dogs need, whereas plant-based proteins might not contain enough of some essential amino acids.
Fats also are found in both animal- and plant-based ingredients and are incorporated into skin cells as fatty acids. In particular, linoleic acid is essential for a dog’s skin and coat health. Without enough linoleic acid, dogs might experience a dull and dry coat, hair loss, greasy skin and increased susceptibility to skin inflammation.
Linoleic acid is found in chicken fat and vegetable oils (such as corn and soybean). IAMS™ research has also found that the fatty acids in vitamin-rich fish oils help promote excellent skin and coat health.
Your dog needs vitamins and minerals for a healthy skin and coat. The best way to provide these nutrients is by feeding a complete and balanced diet full of essential vitamins and minerals, rather than giving him supplements.
Vitamin or Mineral Importance to Skin and Coat Health
Vitamin A Necessary for growth and repair of skin
Vitamin E Protects skin cells from oxidant damage
Vitamin C Helps heal wounds
Biotin Aids in the utilization of protein
Riboflavin (B2) Necessary for fat and protein metabolism
Zinc Necessary for fat and protein metabolism
Copper Involved in tissue, pigment, and protein synthesis
Diet can be a factor when changes in skin and coat condition occur, but the most common causes are season and life stage. As cold weather approaches, most dogs grow a thick coat to help keep heat in and cold air out. As the weather warms up, they shed their thick, heavy coat.
Most puppies are born with soft, fuzzy hair, but as they age, a coarser coat grows. Pregnant or nursing dogs also might experience a change in coat condition or hair loss. And, as with humans, a dog’s hair might thin out and become coarser and white as he reaches his mature years.
