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.
Dogs use a range of sounds to communicate with us and each other. Just as important is the body language they use to tell us how they feel or what they need. How well do you know your pooch’s unspoken cues? Read on to find out.
Dogs often stare at their owners because they love them. They want to make sure you’re okay or find clues for what you’ll do next — like making sure you’re not going for a car ride without them.
We love it when dogs do this, too, which has led to this trait being even more prominent.
Opens a new windowDr. James Serpell, BSc, PhD, Professor of Humane Ethics & Animal Welfare at University of Pennsylvania School of Veterinary Medicine, explains: “We've selected dogs for this behavior. Humans love that dogs look up at them in admiration, intense loyalty. One frequent observation researchers have made is that people who handle wild dogs ... they don't look their handlers in the eye like domesticated dogs do.”
Dogs have great hearing. High-frequency sounds that humans can’t hear are especially interesting to them. Head-tilting helps them track down the source. Owners find these head tilts super cute and often reward this behavior, which, of course, makes them do it more.
Dogs yawn when they’re tired, but it’s also a possible sign they’re stressed, impatient or frustrated — like when they’re in the vet’s office, or when you won’t throw that ball you’re holding already!
In a recent IAMS poll,* 90% of dog owners said their pet sits or lays on their feet and 100% of dogs said they love their owners. Dogs are very social creatures and this is a way for them to connect and be close to you. Plus, it keeps your feet warm.
Often called “raised hackles,” dogs do this when they’re nervous, threatened or showing aggression. It’s an adaptation from their wild days of attempting to make themselves look bigger.
Opens a new window Dr. Tammie King, Applied Behavior Technical Leader at Waltham Petcare Science Institute, offered this insight to keep in mind: “What’s important when talking about a dog’s body language is to not take one thing in isolation. You’re at risk of misinterpreting what the dog is trying to say to you. Context is everything.”
So be sure to pay attention to what your dog isn’t saying to keep them healthy and happy. Serving them
