The reason why I can't review this product even though I bought it is because we took the dog to the vet for his problem and it was just a a bad gut problem too much bacteria in the gut so they gave him prescription medicine and glad to say he's all better but I'm glad I have the stuff on hand you know if it if it's if his tummy gets upset again and if it happens again I'm certainly going to give it a try it's a lot less expensive than going to the vet but yeah we took him to the vet because he is an older dog he's a senior dog and we wanted to make sure that they wasn't anything serious going on Happy to say he's fine . We all love our fur babies so much
