The thing about waiting so long to neuter your boy is that marking is not a habit. You will have to work with him and letting him know that marking is not an ok thing to do anymore. (Not that it was in the first place). I neutered my boy at 3 years but it was because I got a female and I didn't want them to have puppies. I recommend using a belly band. My boy didn't like getting wet/peeing on himself and he stopped marking. |
