Great name for a basenji. After Jurassic Park debuted, we called out basenjis velociraptors, seemed to fit their moves, their look…and their ethics (if I can get it, I can eat it)!
As for standing over, probably a tiny dominance thing, or just "ownership", as long as other dog doesn't mind, it isn't a serious issue for them.
i think i got a pic of what you're talking about. my boy Zumi does this all the time with my other two dogs. he will stand over them, sometimes with hackles raised and posturing, or sometimes he just stands there over them, doing nothing at all. It doesn't seem to bother the other dogs, so i don't bother either. the dog he is standing over is only 6 months, but he is a highly aggressive dog, he doesn't seem to care that Zumi stands like this.
