My dogs have been chewing bully sticks for years, but they only have one each about once/month. Last vet checkup, the vet noticed that one of Max's molars was cracked. He had to have the tooth removed and the only thing we could think of was the bully stick. My dogs don't get anything else hard to chew. That said, the vet recommended these and my dogs seem to like them.
