I recall one woman approaching me back in the day and saying, "I have this theory that there's really only one of these dogs, and they just switch owners at night." And after watching many of the videos featuring English Bull Terriers currently on You Tube, I can't also help but be amazed at just how many do look so amazingly alike- even by someone like me who had one and can more readily identify even minor differences in physicality. But it's not just their looks that can be so strikingly similar- it's also their behavior(s).
They're highly excitable laddies, and when in such a highly charged molecular state, they usually resort to two distinct modes of action. One is the circle dance, where they repeatedly (and I do mean repeatedly) pivot in a tight circular bit of frenetic foot stomping; the other being the diagonal dash, which consists of running about from room to room, wall to wall as fast as their muscular appendages can possibly manage- they brake by rearing their bums into the opposing walls and harnessing the resulting kinetic energy to jumpstart the next run into the next wall. Repeat...
Just be alert to the fact that they don't stay in their lanes and will topple whatever's in the way. Mind you, they're just happy- happy to see you, happy to play, happy being... happy!
