Glycogen Replenishment in Hard Working Dogs for how it works

Additional research conducted by the Iams Company recognized that dogs on high-fat diets were better able to burn oxygen, even without extra conditioning. When highly conditioned dogs were fed a normal-fat food and sedentary dogs were fed a high-fat food, the dogs fed the high-fat food were better able to utilize oxygen and had more energy to burn. When the sedentary dogs were conditioned as well as fed the high-fat food, their energy burning ability went up even more.2

...In one research project completed by Iams scientists, racing sled dogs were fed diets of 16, 24, 32, and 40% protein. None of the dogs on the 16% protein food made it though the training season without at least one injury serious enough to remove them from training.
