Mother Nature allows for dogs to eat their stool in times of extreme stress or nutritional compromise. The short digestive tract of the dog can leave live Probiotics and nutrients in the stool. This can promote survival in desperate situations. Your seemingly healthy dog may be seeking some of these unique nutrients. We advise increasing and improving the nutritional panel with BOTH Probiotics and Vitamin Mineral supplements to satisfy the needs of the stool eating or Coprophagia dog. Choose Dogzymes Probiotic Max and Ultimate.
