Traditionally, owners of large-breed and mature/senior dogs have known that their dogs may be predisposed to common joint and skeletal conditions—problems that may affect their mobility and overall wellness. The good news is that specially formulated diets and dog care products can help promote skeletal and joint health and assist in maintaining healthy cartilage.
Including specific nutrients in your dog's diet can help maintain healthy joints. Optimal levels of vitamins and minerals are found in IAMS™ dog care products and promote the efficient production of cartilage.
IAMS has formulas that are lower in fat and calories compared with our other adult maintenance formulas. Bones are the framework of the body, and the more weight added to the frame, the more stress joints experience. IAMS formulas such as IAMS™ ProActive Health™ Mature Adult are designed to help keep large-breed or mature dogs at an optimal weight to minimize joint stress.
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.
