OK, so Beau is not on raw food. But the bones you can buy at pet stores seem to splinter so I am interested in getting him using raw bones which I understand are safer, better for his teeth, and healthier. He is a big time chewer still so I don't want to mortgage my house for bully sticks (besides they have lots of calories). Do I have to freeze bones I get from the butcher? Which bones are best--beef marrow or other? Will it upset his stomach to have some raw when he is not used to it? All advice would be appreciated.
