Great Danes obviously aren’t exactly gentle giants.
I’ve encountered more than one that wanted nothing better than to bite the hell out of me.
Back in the Seventies, my sister was a hippie of note, and when I came home on leave one time, I saw her sitting in a VW Beetle at a gas station next to my parent’s house.
I ran over, and stuck my head in the window to say hello to her, and all I saw was this enormous mouth, completely wide open, huge glistening white teeth, and the mottled pink of the roof of the mouth, with those weird, horrible transverse “ribs” running side to side coming at my face in the car at impossible speed.
I yanked my head back in time to hear a loud SNAP as the jaws closed, fortunately, with none of my face inside them.
I stood there aghast at the close call, and that damned huge Great Dane just sat there looking at me balefully, hoping I am sure, that I would be stupid enough to stick my head back through that window.
I know they can be nice dogs, but I have never trusted any of them since then.
