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 such as protein, fat, vitamins, and minerals are important players in the skin and coat health of dogs. To understand the role of these nutrients, it is necessary to start by understanding skin and hair.
The purpose of skin and hair is to block things from leaving (such as water or heat) or entering (such as viruses and bacteria) the body.
The hair coat is composed almost entirely of protein. If the animal's diet doesn't contain adequate protein quantity and quality, hair may fall out, or become dry, weak and brittle.
Skin is made up of squamous cells, flat cells tightly packed together. These cells have tough membranes that are composed of proteins and fats. Without proper amounts of these nutrients, cell membranes weaken, allowing water to escape and bacteria and viruses to enter more easily.
Proteins are found in both animal-based and plant-based ingredients. Animal-based proteins contain all the essential amino acids dogs need, whereas plant-based proteins may contain only some essential amino acids. Animal-based proteins help dogs achieve optimal health.
Fats can also be found in both animal-based and plant-based ingredients. They are incorporated into skin cells as fatty acids. There are two essential fatty acids for skin and coat health. Linoleic acid maintains skin and coat condition in dogs. Without enough linoleic acid dogs may experience dull, dry coat, hair loss, greasy skin and increased susceptibility to skin inflammation.
Both of these essential fatty acids are omega-6 fatty acids and are found in animal tissues like chicken fat. Linoleic acid is also found in some vegetable oils, such as corn and soybean oils.
Most commercial dog diets contain more than adequate amounts of omega-6 fatty acids. Because these fatty acids can be converted to compounds that increase susceptibility to skin inflammation, it is important to balance the amount of omega-6 fatty acids in the diet with omega-3 fatty acids, which reduce susceptibility to inflammation.
Omega-3 fatty acids are found in oils from fish and some plants (canola and flax).
IAMS research has found that combining fat sources in the diet at a ratio of 5-10 omega-6 fatty acids to 1 omega-3 fatty acid results in excellent skin and coat health.
Vitamins and minerals are essential for the development of healthy skin and hair coat. The best way to provide these nutrients is through a complete and balanced diet containing appropriate amounts of essential vitamins and minerals rather than through 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 |
| 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 is often believed to be a factor when changes in skin and coat condition are noticed. The most common causes of these changes, however, 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 begins to warm up, they shed the thick, heavy coat.
Most puppies are born with soft fuzzy hair, but as they age, a coarser coat grows. Pregnant or lactating dogs also may experience a change in coat condition or hair loss. And, as with humans, the hair on dogs may thin out and become coarser and white as they reach their senior years.
