Nutrition and metabolism of the geriatric dog.

Sixteen 10-12-year-old and eight 1-year-old dogs were studied over a two year period to determine comparative differences in physiological response to 4 diets varying in protein content and percentages of energy contributed by protein. The ability of old dogs to utilize nutrients as supplied by these foods was not significantly different from that of young adult dogs. Except for indices of mitogenic stimulation and serum urea nitrogen (SUN) other physiological parameters studied were not affected by the diet fed. Regardless of diet, old dogs had significantly higher serum levels of cholesterol, phosphorus and alkaline phosphatase and had lower indices of mitogenic stimulation than did young dogs.
