Yep, it's just a normal wee - although not necessarily quick, they can spend ages trying to decide the best spot to do it.

It's a kind of 'Kilroy Was Here' type of thing, or grafitti tagging - leaving messages for other dogs. Someone on here once described it as sending and checking peemails - which is about right.

They'll do it over other dogs scent, often trying to cock their leg as high as possible ( a macho thing perhaps to make them seem taller than they are ) and keep doing it on a walk even when there's very little left to squirt out. I don't think it's
that common really for dogs to do it in their own home though, mostly just outdoors on top of where other boys have been, or in prominent places where another dog will get wind of it.
