Apologies if this is the wrong place, this morning I've found rubber like stones in my dogs poo. (- He dont chew toys, and is a good dog when comes to only eating food and nothing else) Last week he was at the vets and was given a paste to help digestive function as he's pooing routine hasn't been his normal.... could this be due to the paste or something else and needs to go back to the vets? Thank you and sorry if tmi
