My apologies; it was a chicken intended for chicken. It was a roast chicken wannabe. It was a pre-roast chicken. Apparently (or so the vet said) uncooked bones are fine as dogs crunch through them - cooked is dangerous.
Besides, Tillie's jaws are literally twice the size of a Staffie's. I kid you not. She could hack through an elephant's foot with only a lady like burp.
Raw chicken is quiet safe, bones and all, and a preferred food for raw feeders. Might I suggest some mousetraps on the countertops for a while? As someone who lives with two very large dogs I have found this to be a very effective method of curing countersurfing. They will not hurt a large dog but the discovery that the counters make noise and bite usually stops them countersurfing pretty effectively.
