There's nothing more distasteful to a dog owner than seeing their dog eat its own stool. Coprophagia (the consumption of feces by an animal), however unpleasant, is not an abnormal behaviour for a dog & to help thwart this problem Mark & Chappell have launched Stool Repel-UM tablets. When the active ingredients in Stool Repel-UM are ingested they become activated in the small intestine & will help produce a stool that is unpalatable to the offending dog. Suitable for dogs & puppies aged 6 months & over.
