My dogs are big chewers, if I don't give them something to chew they find something else LOL, so i give them Bully sticks. Those are 100% digestible, unlike rawhide and other treats like that, and so far we have never had an adverse reaction, choke episode, digestive upset, or any other problems we ended uphaving with other type of chews. For myself bully sticks are the only things I give to chew, except raw knuckle bones once in a while, oh and I tried those big stinky hooves once, the ones that are like whole feet, but they don't work as well for my dogs because of their mouth structure and cracker ended up with chin sores from it, so I don't give those now. The bully sticks work the best for me, but everyone has to decide what works best for themselves and their dogs because each dog is different, some are aggessive chewers, like mine, and some just nibble on things, so it's really all relative as to your dog's chewing style.
