I have a question about giving Basenjis certain "treats" from the butcher…they gave us some scraps for the dogs (leg bones and rib bones with some meat left on them) and they said it'd be best to boil them first but is it necessary or can the dogs have them completely raw?

Oh no dont boil them!!!
Raw bones are perfectly fine for dogs, boiled or cooked bones are not! Cooked bones can splinter and be swallowed which is very bad.
Leg bones, such as marrow bones, wont be consumed except for the marrow but they may enjoy chewing them. Rib bones are soft enough to be completely consumed.

Yeah that's what i thought….i thought it'd be kind of weird to have to boil them first.
