Can dogs eat beef bones? My dog loves them (the raw discarded sort from butchers or rib joints) but when I give him one he goes crazy, actually consuming the bone and digging into the marrow. It worries me, but I've heard the marrow is good for them. But every time I've given him one I've had to take it away because he just gets too crazy. I know they can't have chicken bones (obviously, ow!) but what are the risks of giving him a beef bone as an occasional primal treat, even if it means he'll likely chew the whole thing up?
