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.
Low-cost food might be better for your wallet, but it can be a raw deal for your dog, because he may not get the nutrition he needs. Premium foods, such as IAMS™ ProActive Health™ Smart Puppy Original , make sense both nutritionally (because of consistent, high-quality ingredients) and economically because they provide:
The investment in a premium food might initially cost more per bag, but because these high-quality formulas are high in nutrient density, your dog may need less food, which can offset the higher cost per unit of weight. On a cost-per-feeding basis, look at how much you feed each day as opposed to how much the bag costs, because nutrient and energy density will generally be lower for a low-cost food compared with premium foods.
With budget-priced formulas, the emphasis is on production and ingredient costs. Two bags of the same least-cost formulated food can have different ingredients and/or levels of ingredients. Plus, those ingredients may vary significantly in digestibility. This means, simply, that you may need to feed more just to equal the nutrition offered by a smaller amount of a premium dog food formula.
High-quality, complete, and balanced premium dog foods such as the IAMS brands are specifically designed to provide your dog with a food that has:
To determine how much food to give your dog, check the daily feeding recommendations set by the pet food manufacturer and read the label. To calculate portion sizes, divide the total daily recommended amount by the number of times (usually two for adult dogs) you plan to feed your dog.
To tell if your dog is at a healthy weight, move your hands along his sides. If you can feel his ribs, he's about right. Or, look down at him when you're directly above him. You should be able to see a waistline.
If he's gaining or losing a lot of weight, slightly decrease or increase his daily intake and weigh him in another week. If you have specific concerns about your dog's weight, talk to your veterinarian. He or she can assess your dog's needs and make a feeding recommendation.
Once you've decided on a premium formula, you have another choice to make: dry or moist. And what about biscuits?
Premium dry dog food gives you the best value and convenience, while fortifying your dog with high-quality nutrition. Premium dry foods come in a number of bag sizes and formulas suited to size, life stage, and activity level. Dry food also helps keep teeth clean, and it stays fresh for a long time if you store it properly.
Wet foods from IAMS provide 100% complete nutrition. IAMS ProActive Health Puppy Biscuits make great treats and rewards and can add taste variety to your new dog's diet.
