This is a great dor or cat deterrent. When I read amazons reviews it only received 2 stars, but my vet gave me this for my puppy who was eating his poopsicles like a frozen treat. Five stars are not enough. It is a white powder packet, you sprinkle right on your dogs food, if he tastes it, you would never know, my dog inhales his food with half of this packet per each meal. And I haven’t seen him near any stool ever since. If you have more than one dog, sprinkle half a packet on their food also to prevent stool eating dog from eating other dogs stool.
