Yes my pets have definitely gotten me once or twice.
Barring the obvious puppy teeth when my two labs were pups, one incident will always remain clear in my mind.
I was on my knees wrestling with my younger lab, and at one point i had swung my head down just as she tried to rear up to puppy Karate Chop me with her front paws.
My chin and the top of her head met, which caused my lower jaw to clamp down. For whatever reason, instead of just snapping closed, my lower right incisor connected with my front right upper incisor right on the bottom point of the upper tooth. I chipped my tooth significantly and I eventually had to get a bonding on the upper incisor to prevent myself from looking like a redneck.
After the incident, I contemplated getting a mouth piece :laugh: , but then I realized that I needed to act as a dominate male and not wrestle with them at all to maintain the pack hierarchy. Even though it is "play-wrestling", if you don't always maintain a superior position at ALL times, it can be construed as a weaknees.
Rather than wrestle, I trained them vigorously, and exercised them properly. (not trying to knock you OP, you can do whatever you want with your own pet. This is just the path I chose)
