Ok, I currently own an F2 male. He's one and a half years old. We reciently got a high content female pup, 7 weeks old. Now my male is marking everything and everywhere she goes. It's bad enough that the pup is having a hard time potting training...much harder than my male, but now he's peeing on everything. And no matter what I do, he won't stop. I'm about ready to find the pup another home because of it. Does anyone have any idea on how to stop this behavior?
