Diet plays an important role in the endurance potential of canine athletes. The Alaskan sled dog might be considered the ultimate canine athlete, sometimes pulling a sled more than 1,000 miles in subzero temperatures. Providing a well-balanced diet is essential to meet the special needs of dogs in such nutritional-stress situations. Not only should the diet fed to these dogs be high in protein, but it also should be high in fat, which serves as the major energy source for exercising muscles.
A high-fat diet can help muscles burn fat more efficiently. During sustained exercise, fatty-acid oxidation is the primary source of energy for the muscles. Increasing the efficiency of fat metabolism spares the body’s use of carbohydrates, and because most dogs have in excess of 10 to 50 times more energy stored in fat than in muscle glycogen (carbohydrate), this might boost the animal's exercise performance.
IAMS™ studies1 have shown that in trained sled dogs as in ordinary dogs, exercise performance was enhanced by switching from a low-fat to a high-fat diet (from 25 to 65% of calories from fat), as indicated by increased:
When dogs were switched back to a low-fat diet, all of these criteria decreased to their previous values.
These results indicated that by increasing the availability of fat stores and capacity to metabolize fat for energy, a high-fat diet promotes exercise endurance in canine athletes.

Oral care is a key component of your pet’s overall health: A smart regimen can help prevent the development of serious conditions. Keeping your pet’s teeth clean and bacteria-free results in more than just healthy teeth and fresh breath. With a little know-how and effort, you can protect your pet for a lifetime of companionship.
Tartar and gingivitis are the most common problems seen by veterinarians. The majority of dogs will develop these problems. Unchecked, these can lead to periodontitis and serious health concerns for your pet, up to and including, tooth loss and serious illness. But you can take action to control this and promote good oral health by incorporating the 3Ds: Daily Brushing, Dentistry. and Diet.
Daily brushing of your pet’s teeth will remove plaque and slow the development of tartar. When first beginning to brush, be gradual and make it a pleasant experience. Start by using your finger. Later, introduce a toothbrush. Be sure to praise and reassure your pet while brushing. Also, reward your pet afterward with play or a walk.
Talk with your veterinarian about annual or semiannual teeth cleaning—a dental prophylaxis or prophy for short. Teeth cleaning, performed by your veterinarian, is the only way to remove tartar.
Diet is important to good oral health. The mechanical, brushing action of dry, crunchy kibbles helps remove plaque and works to scrub teeth clean. Some diets also might include ingredients such as hexametaphosphate (HMP) that can help block tartar formation. Diet, daily brushing, and dentistry helps break the plaque-to- tartar cycle and optimize oral health.
