If your dog has food sensitivity leading to stomach distress, we suggest that you start out by giving only 1/2 - 1 chew crumbled in their food until he/she is used to it. It's hard to determine underlying cause of a dog's tummy troubles based on what they are prone to eating when nobody is looking (at least this is the case for our dogs!) If a problem like that persists after using the chew crumbled in their food, then it may be a rare sensitivity the dog has to the specific soft chew.
If there is an allergy to an ingredient such fish, you should contact your veterinarian to determine the specific cause and the correct course of action.
