So far the bones I've seen produced have been ground into tiny bits. He must've chewed thoroughly.

He didn't have any evil accidents while I was at work today (just a benign accident of the sort one would expect after stuffing an innocent canine with 3 or 4 days worth of food and treats - I told him it wasn't his fault).

Keeping my fingers crossed.
