They are so far surviving here as the diet is minimally supplemented by purchased rations.
They say don’t give your dogs chicken bones, etc. Wonder what they did before we came along.
In over 20 years I’ve only have to remove bones from dog’s mouths twice. Pork, as I recall...
Raw chicken bones are fine. It’s the cooked ones that splinter on them.
As a food service professional, I do have to advise that there is a MAJOR difference between cooked and raw bones.
I won't feed anything cooked bones, except humans. In theory, humans aren't supposed to gnaw bones and break them (In theory, practice may vary).
