Log-in Dog Food Guidelines Adapted from The Veterinarians' Guide to Natural Remedies for Dogs, by Martin Zucker. Animals in the wild don't eat just meat. They eat everything when they kill their prey, including the intestinal contents. In a rabbit, the intestinal vegetable contents amount to about 40 percent of body weight.
Animals also eat bones, a source of calcium for the body.
These diets are high in sugar, chemicals, dyes, propylene glycol, and other additives to give them shelf life, softness, and an artificial look. Their labels make for interesting reading, and that's about the most you can say about them. The cheap generic and store brands have been incriminated in veterinary literature for their poor quality. They are infamous for mineral deficiencies, particularly zinc. They are adequate in most cases for most normal, healthy, young to middle-aged animals, but they are not optimum.
