Excuse all of the posts lately, but I'm an anxious new owner. Anyway, Jasper (14 week old sprocker) just gleefully humped DS1's leg. Now, obviously much hilarity ensued, but isn't he a bit, um, young for such activities? And is it total bollocks that this is a dominance display? Because it didn't look very dominant. Or proficient, tbh.
Ours has humped since he was a few months old, but only his bed. Now at 14 months he doesn't do it much, about 3 times a week he'll suddenly stop playing, chewing, lounging on settee etc, look preoccupied then head for his bed in the utility room and have a quick hump then come back and carry on with what he was doing. All very civilised, we've never thought of it as a problem.
My puppy humps her large toy rabbit. She is just over 4 months old! She is very funny.....I gave her a look like this ----> and she stopped! I'm not that bothered really but obviously don't want her to turn into a leg humper! I guess they just grow out of it?
