I have a male neutered dog who has started marking his territory. He hasn't done it at my house but whenever we go somewhere else he pee's inside. How can I disiplin this?

Don't let him off leash. If he can't sneak off and pee, then he won't pee in someone else's house.

My female does the same thing. She will scent pee in my boyfriends house. I don't let her out of my sight the entire time she is over there..

If he is not peeing in your house, then there really is no need to dicipline this behavior. Just don't allow it to happen. If he cannot be trusted off leash, then keep him on leash right next to you. Tie him to you. Hes little, bring a crate. Let him earn his freedoms.

Okay, I was scared to disipline him when it happened because I didn't know if it was disiplinable(Is that a word), it's wasn't like he had to pee... But I guess he'll be leashed from now on..
