WARNING TO DOG OWNERS.
If you have hollow knuckle bone slices for your dog, it won’t have this listed as a warning, but there are PLENTY of internet results of this happening. My dog was on her last of the pack when this happened: the bone slipped over her canines and got stuck on her mandible - wouldn’t even budge. I had to go to an emergency clinic at 2 am to have them sedate my dog and cut off the bone with a saw. That plus her pain meds was EXPENSIVE. And the vets said they saw this a lot.
DON’T GET HOLLOW KNUCKLE BONE SLICES FOR YOUR DOG.
