Two GSP brothers have free rein in a school field out back. We keep them away from people at the playground or ball field, and all is good. Never have had a issue. Today the not lead dog just took a steady jog (~50 yards) over to a guy who had a tripod and was filming (this was weird), and straight up lifted his leg on the guy! The guy later scoffed about the pee being on his leg and shoe. Then he took off and wouldn't take any help from my wife. Plus the guy had no reaction (or movement) whatsoever as the dog approached. And he didn't even notice the dog lifting his leg, as the guy didn't move until he felt a warm, wet sensation on his leg. The dogs are like 98% solid on coming back when called, but he kept going and just did the dirty deed. What's the dog psychology here? . The alpha dog stuck with me and didn't run over to the guy.
