they do it to stop getting themselves wet with urine
Urination in the dog world is a sign of dominance or possession. When a dog lifts its leg on something, it's saying to the other dogs that sniff it, "This is mine." By lifting his leg on a human, a dog is assuming a dominant possessive role toward that person and more than likely needs some serious training.
Only MALE dogs will do this and it's simply so that they can mark their territory by spraying on other objects. Also, it reduces the likelihood that they will piss on themselves.
No I don't think you can because the flip flop is very light and not hard so when you hit it against the dogs leg it will not hurt. The dogs leg is hard and sturdy.
Im sure you mean why do boy dogs lift a leg and girl dogs don't. Well, the answer would be because if boy dogs tried to "go" without lifting their leg up they would just end up peeing on their leg. and somehow they know that they dont want that.
