same problem over here.. junior pee'd on a girls UGGS the other day.. i tried to tell her not to come over until he went but she was hard headed and got peed on.. he does it when he gets super excited about people coming over or other dogs.. i dont scold him i just try and take him to a quiet location first ( a bit hard when you live in a city atmosphere) but let him go first and than he can play.. that way its a bit less pee to piddle on people.. im hoping he well grow out of that...
