The reason pineapple works is because it contains it enzyme called Bromelain, which is the same thing use in many meat tenderizers. This enzyme works by breaking down the protein in food and enabling the dog to digest it the first time around. If a dog smells undigested protein in the poop, he thinks this is nourishment and will eat the poop. Some dog foods have an easier to digest protein, and switching foods can stop poop eating as well. |
