My girls absolutely love them too. They chew on them all the time if I let them. I have noticed that when they have them they do not eat as much food. Anther drawback is Suzi our yorkie. She has her own bully stick , but always takes the other one from our Tzu and hides it. Then the 2 of them will fight over the one. So my son and i have to find the other one and make sure both dogs are happy. my goodness it is like having 2 babies fighting over a toy
