Same with my dogs, LuckyPenny. I used to give Oxford the big marrow bones before she was on raw, and she loved them. But now they are on a full raw diet and I still give it to them on the days I fast them. They love it and it keeps them busy. I actually stopped buying dog toys because they dont even play with them, all they do is gnaw on the old bones. Its like a bone yard on our living floor.
Kristin-if you are worried that Guinness may swallow the bone, try giving larger ones, like the marrow bones. I dont know much about the knuckle bone, but other in the forum have advised me that the cartilidge is good for their joints. It seems that your dog know how to handle eating bones since he shows signs of chewing up well before he swallows them.
