These Stool Repel-Um tablets (30 tabs) by Mark and Chappell are ideal the solution to discourage your dog or puppy from Coprophagia. Coprophagia is the condition whereby dogs will consume their own or other dogs faeces, which is of course highly unhygienic. These tablets work because the active ingredients are absorbed into the small intestine in order to produce a stool which is not palatable. Stool Repel-um tablets have a palatable taste of chicken liver, and are non-toxic. They are suitable for adult dogs and puppies over 6 months of age. Always consult the enclosed instructions for dosage recommendations.
