My dogs love bully sticks.
I know where they come from. I'm not sure if I just don't think they are gross or if I am just so used to giving them those sort of things. lol My dad used to be a butcher so our dogs always got plenty of stuff like that.
My dogs get a lot of meat type items, raw bones, pigs feet (sometimes even the legs) pig tails, cows feet (the WHOLE foot, hoof, ankle & all) etc... etc...
