Good to know. My husband fed my dogs pig ears for the first time years ago. The explosive results convinced me more than enough to never allow that again. Also, the way they are shaped, and the horror stories I heard about them getting lodged in their teeth or throat, I had no reason to use them. Most commercially available dog treats are 'feed at your own risk.' I usually go with those giant milk bones and freezedried treats. Carrots, vegetables and fruits are great to use as treats as well.
