I would stay away from those things!! I don’t even give Bully Sticks or Texas Toothpicks to Peanut anymore, and you know I have had no tummy issues!! Seemed like everytime he chewed on a Bully Stick he had tummy troubles.. I talked to my vet about them and he said bacteria can grow on them! The last time Peanut had a Texas Toothpick he got Pancreatitis! I know Peanut is just sensitive, but be careful what your baby chews on
