Gosh, some of the posters to this thread really try to start something!
The OP was upset, been there, done that, we all probably have. Dee said nothing wrong, for heaven's sake, don't make it into something that's it's not.
So much drama, then the thread goes back & forth forever. Give it a rest and try to help the OP.
As for the OP, I have a 1 /12 yr old that I raised from 10 weeks. Scooter was neutered @ 6 months.
He did not start this right away after being neutered and he was totally house trained. He peed on my feet, my DH's lap (several times) peed on the head of the older dog, Harley, peed on Rita the first day she arrived, peed on a new toy. He did this even after coming right in from peeing outside. I don't think your baby is doing it because of the neutering. I believe he is "marking" you, and showing dominance as the Alpha Dog. Scooter also has peed on each of the new puppies(2) that I got a week ago. When any of the other four dogs go pee outside, Scooter goes right over and marks where they peed. He doesn't peed on me or DH anymore, and only did it to each of the dogs once. In Scooter's mind, everyone & everything is HIS. When your baby does this, think of it this way... YOU HAVE BEEN CLAIMED BY HIM! Even though it's gross to us, it is their way of saying, I want you as mine. He must think an awful lot of you
Rest assured that once he feels he has make his point and mark, he will stop.
