Harley was almost 3 when I got him. He was not netured and had been used for breeding. The first time he walked in the house he lifted his leg and pee-d on me
...walked over and did the same to my husband and son in about 30 sec. flat!!! The next day, while I was BUSY sewing belly bands, he marked on everything in my house, thank goodness I have wood laminate floors! I waited a week before he had his surgery, I wanted him to get used to us first. He marked 3... maybe 4 times after surgery, but I have not seen him or found a single spot in the last month! I cannot believe how it has calmed him down, it has just turned him into a little lover boy. I still watch him close, and keep a can with pennys in EACH room so I can grab/shake/and BAD BOY him just in case. It worked great for us....am wishing you good luck with it too.
