Abstract
Abstract The object of the invention is to provide a dog food of improved acceptability. Dog foods, no matter how nutritious, must be palatable for the dogs to receive the proper nutrition. This invention provides a dog food of improved palatability by the use of amino acid palatants selected from the group consisting of L-phenylalanine, L-tyrosine, L-tryptophan, L-methionine, L-arginine, L-isoleucine, L-leucine, L-serine, and any combination of these. The palatant is employed in any effective amount, usually from 0.001 to 0.8 wt. percent, on dry, intermediate-moisture, or canned dog food.
