Your dog has stinky breath, too? I found a trick that will sweeten his breath and turn it into just plain hot breath without the stink. Albertson's has huge knuckle bones that a butcher will custom cut for you. Don't buy the middle part. Just request the huge end knuckle which is larger than the size of a grapefruit. I have him cut the knuckle in two, but your big boy probably doesn't need it cut. Bake the bone on a raised rack for 2 or 3 hours until all the grease is baked out. After it cools, then let him have it. Kind of like brushing and flossing every day. The gnawing action really scrapes their teeth crystal white and their breath won't be so vile!He's a sweetie and would love you 'til the end of time if you let him...stinky breath though
