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!


As your dog matures, his body functions change. He might have decreased immune-system function, deterioration of skin and coat quality, and more frequent intestinal problems. So it makes sense that what a mature dog eats might also need to change.
Throughout a dog's life, a process called peroxidation occurs. This is a normal process the body uses to destroy cells that outlive their usefulness and to kill germs and parasites, but this process also can destroy or damage healthy cells. As a dog ages, the damage caused by peroxidation accumulates and, in turn, increases the risk of certain problems such as infections.
Antioxidants are naturally occurring components in the body (but also can be acquired through diet). They help maintain overall health by neutralizing the peroxidation process of cellular molecules.
Research sponsored by IAMS™ found that dogs fed a diet rich in antioxidants such as vitamin E had improved immune responses and vaccine recognition. This might be especially important for mature/senior dogs, because IAMS research has found that, as dogs age, immune responses can decrease.
Eating a complete and balanced diet with omega-3 fatty acids, such as those found in vitamin-rich fish oils, also helps rejuvenate dry skin and develop a healthy, lustrous coat.
Aging dogs might have higher numbers of unfavorable bacteria and lower numbers of beneficial bacteria in their intestines, which can result in clinical signs of gastrointestinal problems (such as diarrhea). A diet with a moderately fermentable fiber source such as beet pulp can help maintain intestinal health. Beet pulp provides energy for the cells lining the intestine and promotes proper stool formation.
Different dogs show signs of aging at different times, and much of this variation is associated with size. Larger dogs generally appear mature/senior sooner than smaller dogs. The table below can show you when your dog should start a mature diet with a food such as IAMS ProActive Health™ Mature Adult.
