I have the same potty problem!!
I have three young dogs who pottied in the same spot.
When Xella was a puppy, she peed in the corner in my room. I scrubbed the carpet like CRAZY! Over and over again she peed. I tried every product, home remedy, anything to make the scent go away.
When Xander was a puppy, he peed in the same area! I rented a carpet cleaner machine, cleaned the area four times, and then let it dry. I used the no potty sprays but they only seem to work for a few days. He stopped peeing for a while.
Now my four month old yorkie puppy Sofia pees there. No products I have tried worked! This Thanksgiving weekend we are ripping up the carpet. Last resort! Sofie doesn't pee there anymore, she's trained now, but the smell from the past two years makes you faint! The smell gets worse and worse as bacteria continues to grow under the carpet.
Haha, it's terrible, really. The only thing I can do now is block off all carpeted areas and take them out every thirty minutes to an hour to pee.
