I have two 14 week old Cairn Terrier puppies who want to eat EVERYTHING including, you guessed it! I’ve used this product for 3 days now and so far, so good! They want to totally stay clear of their feces instead of eating them! All you do is sprinkle some of this (different amounts based on dog’s weight) and mix in their food. (Currently used over dry food.) Makes the excrement taste awful so they don’t want to eat it or in my case, even go near it! So far, so good!
