Quick answer: The Benebone Wishbone is a hard nylon chew toy shaped for easy gripping. Many dogs enjoy chews like these, but veterinary dentists warn that very hard chews, including hard nylon, bones, antlers, and hooves, are a common cause of fractured teeth, especially the large upper chewing teeth. Choosing chews with some give, supervising chewing, and replacing worn chews reduce the risks.
The fingernail test
A common rule of thumb from vet dentists: if you can’t make a slight indent in the chew with your fingernail, or it would hurt to hit your knee with it, it may be too hard for your dog’s teeth.
Safety tips for any chew
- Choose a size larger than your dog’s mouth can fit whole
- Supervise chewing, especially at first
- Replace chews once pieces break off or edges become sharp
- Take it away if your dog breaks off and swallows pieces
- Check teeth regularly for fractures or discoloration
Signs of a broken tooth
- Chewing on one side or dropping chews
- A tooth with a visible pink or dark spot
- Facial swelling or drooling
See your vet promptly. Fractured teeth are painful and can become infected.
