I have used this product for years, being a veterinarian technician for 15 years. I have used other products for stool eating and I have found that Forbid is the most effective in stopping the habits of dog eating both cat and dog stool. Just put it on the cats food or whichever pets the dog is eating. Even their own food. It appears to be tasteless, both my cat and my dogs ate their food with no hesitation. I highly recommend this product over any I have used.
