I gave my dog a roast beef bone, and after about 2 minutes of sucking on it he started to rub his nose on his bed. I immediately took the bone away from him. He did a few breath grunts, but stopped rubbing his nose. Do you think it was the start of an allergic reaction. He did not injest the bone, he just sucked on it for about 2 minutes.

I don't know but I wouldn't chance it again.

Some dogs are allergic to beef or chicken, was the bone cooked? I would be more on the lines to think it may have been seasoning that the bone was cooked with rather then the actual bone.
