I do agree that they shouldn't worry if they have already given some oreo's to their pet, but,a pet cannot choose what it eats and it is strictly up to the owner to insure a healthy diet. Even simple carbs alone, white bread, things with white sugar, hydrogenated oils, that stuff is so bad for...
Coa coa the stuff that is in chocolate is in the cookie part of oreo's if you have already done it and your dogs OK don't worry now. But don't do it again because coa coa is poisonous to dogs and is bad for the heart and oreo's are very far from a dogs natural diet. They are bad enough for us...
