It is not uncommon for dog-people I like, respect, love and consider friends to criticize me for failing to feed my dogs bones. While I understand many dogs have no problems with bones, I see this kind of thing at least 3 times a week... Maybe this will help you see why bones may be right for some, but aren't right for me.
Dog #1 came in because of her facial swelling and refusing to eat for 2 days.
Here is what her tooth looked like: small chip fracture with formerly open pulp chamber.
Here is what her xray showed: tooth root abscess caused the facial swelling.
Culprit: Raw knuckle.
Dog #2 came in for refusing her food for 3 days.
Here is what her tooth looked like once she was anesthetized and we could touch it without her feeling pain: massive open slab fracture.
Here is her xray showing the break.
Culprit: Frozen chicken back.
Maybe all the dogs I see at work just have bad teeth. There is plenty of natural variation there. I just figure I'd be one of the unlucky ones with a dog with bad teeth. So I hide behind my softer chews and a toothbrush.
