“Coprophagia” (eating of stool) is a common behavioral nuisance in puppies. Most pups outgrow the habit. Disgusting as it is, dogs can obtain some nutrition from previously processed cat food in the form of cat feces. Likewise they derive some small nutrition from their own feces. Treating the pet’s food with Meat Tenderizer 20 minutes prior to mealtime is often effective. There is also an effective product on the market (Forbid) to be mixed with the food prior to offering.
