I have always heard never to feed your dog cooked bones due to the fact that they splinter into shards when cooked which can seriously mess up the digestive system.
Since being carnivore I've made a lot of bone broth and I'm often left with mushy bones like the ones found above, some times so mushy it's hard to separate them from the meat without crushing them. This is caused by pressure cooking them for hours on end.
Lucky for me this is amazing, nutrient dense dog food and those little hunks made delicious dog snacks too.
