I am concerned Molli is 'marking' when I take her other places. She never has accidents in our house but if I take her to someone else's house she pees on the floor. She does these weird little pee spots and sometimes will do 2 or 3! I show her where the pee pad is in the house and take her out first thing. She uses the pee pad but also will pee on the floor. She has become very alpha so I worry she is trying to mark her territory. Is there a way to get her to stop? I am hoping to get her working as a therapy dog but we can't do that if she is going to pee inside.
