My Blue Heeler does that. Nips my ankles.
we had a black lab, and they do what i call a ‘squat butt mad-dog berzerker run’ where they lower their butt and run flat out with a berserk look on their faces- then they leap at you mouth wide open- and do about a 1/4 bite- hard enough to kinda hurt, but not a full bite by any means-
It’s really funny to watch em go mental for a few minutes lol- have seen other labs do that too-
You can kinda see it here at the 56 mark- but outdoors they go really mental- so funny to watch.
