Well...not quite wolves..........We have a part-time springer spaniel, and just recnetly DS (nearly 1 yr) and her have become fast chums.
now, springers are very fond of wandering around with toys/shoes/socks etc in their mouths for long periods(it's the breed),and i've noticed DS has started doing it too - he's never crawled on his knees - he's always been straight-legged, and it really looks like he's copying her
i've never seen any other kid do this - apart from a friend's son (nearly same age),and they also have a (full-time)springer.
