[Mista and Flop]

Hello,

I have two precious Maltese Shih-Tzu's - one is 14 months old and the other is 11 weeks old. I carry my baby puppy whilst I walk my older puppy each day in the dog leash free park where he loves to go and play with the other dogs. Once whilst in this park, a few months ago, my older dog urinated on someone's leg. He has since done it again -twice! Once could be classified as a mistake. Twice was unfortunate, but 3 times would indicate that it is becoming a pattern. I am hugely embarrassed by this behaviour and wonder what is going on for my dog to make him want to do this. Does anybody have any clues as to how to stop this behaviour?
