Question

Why do dog only eat other animals​

Answer 1

Answer: This can occur because one dog has less of an appetite than the other and leaves his food for your other dog to clean up, or one of your dogs may be dominant over the other and takes the more submissive dog's food. This results in one dog getting too much food and one dog not getting enough.
