so sorry to hear that man.
i never give my dog bones, after the incident happned...
my dog was 4 years old. we had pork ribs for dinner, and my dad gave him a small bone to chew, he started to stagger and blood was comming out of his mouth so we thought he was choking,
rushed him to the vet, vet found the bone wedged in the top of his mouth and yanked it out with a hook tool, a shot and 500 bucks later we where done with that shit and naver has dog been given a bone, again.
also wtf there you thinking giving it chicken bones? they splinter like a bitch.
