I assume there’s a belly nerve that runs down his leg. But does anyone know any more about the mechanics of this? It cracks me up! I know ALL dogs do it, but mine does it the cutest. I also notice that he seems to enjoy having that spot scratched. How come?
I never got it from any official source, but I always equated canine leg-shaking with what would be tickling in humans. Dogs can’t laugh, so, they shake a leg.
NEWS FLASH It was reported today that the laughter-like sound dogs make is in fact, a sound of enjoyment akin to human laughter. Now, if only the news sites would catch up and post these things so I can link to them. grrrr…
I dunno, I always shake my leg like that too, when my wife or her girlfriend rubs my tummy. It just seems natural, like blinking when something’s coming at my eyes. It’s probably a spinal reflex, and unrelated to higher cognitive functioning. If you want, I’ll go to the lab, and cut up some dogs and see what I can find.
Actually, I don’t have a Far Side calendar. So I feel a little under-privileged.
I do, however, have an 8.5 week old black lab puppy that I got Saturday. Maybe it IS tickling him. But humans tend to avoid ticklish sensations, whereas my puppy rolls over and just BEGS to get the leg shake thing going.
I’ll have to try that stiffy thing out on the bf later…
All three of my dogs will do the same thing even if I scratch their backs, so it’s not just the belly. My cats, on the other hand, will not ever mimic scrathcing themselves, no matter if I rub their backs or their bellies. If I am petting the cats’ backs, however, especially near the tail, then I get the rise-up of the cat-butt…AKA “cattatude”.
This just in: My new puppy shakes his little leg when I scratch behind his EAR too! Weird! I bet he’s the only dog EVER to do this. I knew he was the best furry friend in the world and the most unique. My dad says he did that right out of the womb. Weird!
One of my Mom’s cats… Correction, one of the cats which cohabits with my Mom has a birth defect in her back legs which prevents her from scratching herself properly, so she loves it when anyone else scratches the back of her neck for her. When this is done, she invariably reacts by wiggling her leg, as described. I’ve always thought it was the way Attrayant described, that “I’m being scratched, therefore I must be scratching”.
