Urinating...maybe a behavioral issue?

Question
First let me thank you for any help you may be able to give me on the subject because I am thoroughly out of ideas!

I own a two year old Australian Cattle Dog mix named Lucy. I adopted Lucy from the local humane society when she was 8 months old. She was instantly protective of me. and while I had troubles with her being housetrained it resolved itself once she was given a cage which she took very well too. With her protectiveness she is particularly on guard with men. I have a new(and the first serious) boyfriend since I have gotten her. But she has loved him from the moment she met him and loves to play with him and doesn't growl if he comes in the door.(which she normally does with everyone else minus my best friend who shes known since I got her). I believe that she is jealous from not receiving ALL of my attention. She will see us touching and will get up on the couch between the two of us. She will also go upstairs and urinate in my bedroom where I can't see her doing these things(I've since installed babygates to limit her access to the basement and upstairs which is where she has done the urinating). but it is beginning to escalate and she will pee several times in the house while he is here and just last night, we were on the couch together, I went to use the restroom and he went into the kitchen, and she urinated all over the couch where we had been laying just moments before. She doesn't resort to aggressive behavior(she once bit a guy I had over), with him and really does enjoy playing with him and she's not uncomfortable in any obvious way with his presence, minus when the attention is not totally focused on her. I think it should also be mentioned that I moved a few weeks ago, she has seemed to adjust quite fine and knows where to go to indicate if she ACTUALLY has to use the restroom or how to get my attention to let me know. And on average I let her out every 2 hours just to be sure. What do you think is causing this behavior and how can i and/or my boyfriend stop this from happening and help her adjust to his presence?

Answer
It may be stress, and it is likely that she is "marking" territory - making things smell like her. It's gross to humans, but makes sense to dogs. I think you may need to go back to very basic housetraining with her - make sure she's not out of your sight. Manage her carefully, so she doesn't have the opportunity . Thether her to you, use a crate. And go to the vet to make sure there's not a physical reason, like a urinary tract infection. Sandy Case BFA MEd CPDT www.positivelycanine.com
