Twitching and grinding teeth when sleeping | Boxer World ...
2008-2-29 · Feb 11, 2008. #2. I've never seen a pup grind their teeth before, but Hurricane dreams all the time! He will twitch, "run", bark, growl, whine, he used to act like he was nursing when he was younger, hasn't done that in a while though. Every dog I have ever had dreams like that. It sounds like that is what your pup is doing.
