We started our dogs (when they were pups) at 8 weeks old.
So Gunner has some big boy teeth coming in, is it ok to give him his raw knuckles bones or should he stay away from them for a while?
here are over 150 muscles in the jaw that help strengthen the ears with all the tugging & chewing plus helps with teething. Limit the time he gets the bone in case of gut upset from the marrow or small pieces of bone fragments. Increase time as you see fit. You can store bone in freezer in-between times.
