I should add it was my breeder who introduced me to the pressure cooker - she would add home cooked to her kibble, which included bones, water and a bunch of other whatever stuff added in.
We do a raw diet so we don’t feed cooked bones and I wouldn’t feed them the chicken bones from normal chicken stock however bone broth seems to tenderize the bones to almost nothing so that’s the one exception I have no problems with.
I’ve also let them them chew on a cooked ham bones and what not as well, so I’m no purist. But i dont advertise that as its against general guidelines.
I think a lot has to do as well with dogs eating kibble all their life and then getting into the garbage or what not and then gorging out on a cooked chicken carcass. I noticed my dog tend to break open the bigger bones and eat the inside and leave little bits that they don’t find palatable for whatever reason.
