Input: Warning to other dog owners: the edible Nylabones are extremely dangerous for dogs with a big & greedy appetite. My dog swallowed it whole within 30 seconds of giving it to her and choked on it. She was fully unconscious before I could dislodge the bone and breathe into her nose to bring her back to life... We almost lost her over this bone. If your dog is a greedy chewer or eater, then please don't buy edible Nylabones.
Output:
Negative
