We moved into our new house right around Christmas. We've been here over a month, and I've been trying to re-train Kaji to the new routines of this house. That's just something I always do when we move to make sure I set up Kaji to be successful and earn as many treats and cuddles for peeing and pooping in the right place. Long story short, I just recently added the master bedroom in addition to the master bath to Kaji's roam space. Well... I found evidence of him marking.

I cleaned that up, but instead of the room smelling better, IT SMELLS WORSE!!!


I've caught Kaji intensely sniffing in random spots around the house. The kind of intense sniffing that usually precedes Kaji lifting his leg on a tree. He hasn't done this kind of intense sniffing indoors since he came home in 2009 and had a marking contest with my then roommate's dog.
I'm wondering, instead of just cleaning his accidents, am I pulling up other smells from the carpet? Lingering previous owner smells?
I know this will sound crazy, but I know how Kaji's pee smells (oh the joys of being a yorkie mom

) The master bedroom smells like pee, but not Kaji's pee. I'm almost 100% convinced of that.
If it isn't Kaji's pee, and he is being enticed to mark because of pre-existing smells, what do I do? How to I stop this from continuing? Kaji doesn't leave my side when I'm home, I usually stop his intense sniffing when I'm here. The problem is when he's home all alone. How do I clean to stop this from happening again?
