Bully sticks are a single protein chew, made from just one single ingredient....and even dogs with beef sensitivities seem to be fine with them.  Like all of our edibles, they are completely free of additives, including dyes, preservatives, and flavors.  

They don't splinter, they just wear down gradually as your dog chews.

Bully sticks are great for all life stages, even safe for puppies (just be sure to take any chew away when it becomes small enough to swallow).
