I had heard a couple of years ago about the greenies. I never buy them I dont know why they are even allowed to sell them.
Our vet told us to use round steak bones they are just little round bones you willl find in a round steak. Our little yorkie weighs just 2.2 pounds and she has a round steak bone that she chews on all the time she loves it
I hope that your dog was ok from the ordeal
