I try really hard NOT to think about bully sticks! If you know your physiology you know that the bully stick is a lean piece of muscle cut and dried for our puppies use. My little girl needs to chew and I wouldn't dream of giving her rawhide and other chew items are not nearly as safe and healthy.
When I first heard of them and what they are made of I thought "NO! No way am I buying that!" However, with Gracie stealing everything she could get her mouth on and chewing things to bits I had to admit defeat and buy the "sticks." I put a block somewhere in my mind on this subject. I place my order every couple of months and hope that no one else asks me to explain what they are!
