How Fat Affects Your Dog’s Performance

Diet and Performance

  • Share

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.

 

High Nutrient Demands

Dietary Effects on Performance
 

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:

  • Mitochondrial volume—Increasing the volume of the muscle cell's 'power houses' increased the capacity for fatty-acid oxidation.
  • Aerobic capacity—Muscles were better equipped to utilize fatty acids for fuel because of increased ability to utilize oxygen.
  • Fatty-acid oxidation—By increasing fatty-acid utilization during exercise, more energy was released for the muscles to use.

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.

    Puppy food

    The energy requirements of a puppy can be nearly twice those of an adult dog. This means that a puppy might not have the stomach capacity to eat enough food to meet his needs unless the food is specially formulated.

    When choosing a puppy food, select one that provides a highly digestible, nutrient-dense, 100% complete premium formula for growth. Such high-quality formulas contain the vitamins, minerals, protein, fat and carbohydrates your dog needs for sound and healthy development. With a premium formula, your puppy may have:

    • Exceptional muscle tone
    • A shiny, luxurious coat
    • Healthy skin, bones, and teeth
    • Clear, bright eyes
    • Small, firm stools
    • Playfulness
    • A happy, healthy attitude

    Puppies grow fastest during the first six months of life, and because growth rates differ among breed sizes, you need a formula designed to address the needs of your puppy’s breed or size.

     

    Adult dog food

    No two dogs are alike. So when choosing your pet's food, you'll want to take into consideration the dog's breed, size, age, weight, and lifestyle. Full growth will happen at around 1 to 2 years, with the exact age determined by your dog's breed—small-breed dogs mature faster than large-breed dogs. “Grown dogs, especially ones who are more athletic, will start to eat more quantities in one feeding,” says Madan Khare, DVM. “You want to limit his feeding to one or two times a day, depending on his activity level.” Exact quantities should be determined by consulting your vet or by reading the package labels (just remember to split a daily serving in half if you choose to feed the dog twice a day).

    When transitioning your dog from puppy food to premium adult food you want to do it gradually. “Never change a dog's diet abruptly,” Khare says. Here's a schedule for transitioning your pet from puppy food to an adult dog food:

    Daily exercise and a diet packed with high-quality protein from chicken, lamb, or fish and essential nutrients will keep him happy and healthy throughout his lifetime. Premium dry pet food has all of the daily nutrition your pet needs. It helps promote healthy teeth and gums, too.

    “When it comes to feeding your dog human food, I have three words,” Khare says. “No. No. No.” Interfering with your pet's food regimen by frequent change in diet or nutritionally inadequate human food can disturb the animal's digestive system.

    Always remember to pick premium, tailor-made dog food based on the life stage and unique needs of your pet.
