Oh, boy! I thought I was doing the right thing by cooking it. He ate two huge ones! I'll watch out for blood in his poop. I hope nothing happens.

So - it's OK to eat whole bones raw, though? I was thinking that if they like eating bones they must be getting something they need from them. If it's OK to do it, maybe I'll give them raw joint bones every 2 weeks or so.

Thanks for your help, everybody.
