Hi everyone. For any of you with male yorkies who are neutered, how much did neutering change their behavior? How about marking?
Miles is 7 months old, and he's finally going to be neutered. He wasn't big enough until now...plus, he was kind of a late bloomer.

I don't think "aggressive" is necessarily the word, but lately he's definitely been a little more feisty. Plus, he's starting to mark quite a bit. He's good about doing his "big pees" outside, but once in a while I'll catch him marking my bedroom door, the refrigerator, the wall...the list goes on. Did neutering help this, or at least curb it for anyone?
Thanks!
