I have two Labs, Wendy and Lonesome. They LOVE the raw beef bones I get at the butcher shop. Both have beautiful teeth. Wendy is very possessive of any bone within her space. Lonesome has learned to hide his. I have seen him spend over an hour looking for the perfect spot in the yard to dig and hide his bone. When I feel sorry for him I let him in the house to chew on his bone out of Wendy's view and reach. Lonesome's favorite spot to hide his bone in the house is behind the toilets in the bathrooms.
