Q. My Maltese likes to eat grass for upset tummy symptom of allergy to grass! Whatcan ii give him besides peptol bismol?(makes him sick)
A. Do not give dogs human medicine without first consulting a vet.
For an upset tummy you could give him canned pumpkin (look for a dog specific one, and DO NOT buy pie filling). Canned pumpkin is very good for dogs tummies, and it typically helps with any tummy issue your dog is having. You also might want to consider GRADUALLY switching his food... if his tummy is regularly hurting, and his stools are not regular, then the food you are feeding your dog may not agree with him anymore, even if it had agreed with him for years beforehand. It's important to find the right food for your dog. Even the best quality kibble may not be right for your dog.. it's all about finding the perfect food.
Taste of the Wild, Orijen, Ziwipeak, Honest Kitchen, these are all great dog foods to consider.
