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.
Bloat is a life-threatening condition that acts rapidly and can lead to death within hours if not recognized and treated immediately. Unfortunately, the cause of bloat remains unknown at this time.
The scientific term for bloat is gastric dilatation-volvulus or GDV. Bloat is characterized by rapid and abnormal expansion of the stomach with gas (dilatation). This can be followed by rotation of the stomach (volvulus). This rotation closes both the entry to and exit from the stomach. The blood vessels also are closed down, and blood flow is restricted.
What follows is an increase in pressure inside the stomach and compression of the surrounding organs. Eventually, shock will occur as a result of the restricted blood flow. Here are a few key facts about bloat:
Bloat is a true medical emergency, and early identification and treatment is critical to survival.
In the early stages of bloat, the dog will be very uncomfortable. You might see him pacing and whining or trying unsuccessfully to get into a comfortable position. He might seem anxious, might lick or keep staring at his stomach, and might attempt to vomit, without success.
Other indications of bloat can include weakness, swelling of the abdomen, and even signs of shock. Signs of shock are increased heart rate and abnormally rapid breathing.
If you notice these signs, call your veterinarian immediately!
These suggestions could help you prevent bloat in your dog. However, they are based on suspected risk factors and are not guaranteed to prevent the onset of bloat.
Another way you might help prevent bloat is to feed a high-quality, highly digestible food with normal fiber levels.
Feeding management offers the best method available for reducing risk until the exact cause of bloat can be identified. Although not 100% effective, these measures can reduce the number of dogs that face this serious, life-threatening condition.
