Intestinal Lipid Malabsorption is an inherited metabolic disorder affecting dogs. Affected dogs typically show stunted growth and under development compared to unaffected littermates. Indistinguishable at birth, affected dogs develop signs of increased, indiscriminate appetite and produce loose, yellow, and poorly digested feces. Transition to a therapeutic diet with supplemented enzymes may reduce clinical signs. However, as affected dogs mature, they remain smaller and display dietary intolerance to a fatty diet.
