Busy BonesOctober 24, 2008 To say my dog loves the Busy Bone dental is an understatement. She can devour one in less than fifteen minutes, it's such a treat for her. She's a 40 lb bulldogge, and the small/medium bones are perfect. After I started giving her three a week, I noticed an improvement in the small amount of build-up on her teeth. They do create a small mess if your dog is prone to slobbering.
