Had he already begun marking a lot BEFORE his neuter? Because, sometimes, if it goes on too long... it's hard to break even if they are neutered. Is he marking inside or just outside? Personally, I think it's just a male dog thing to do it outside and I don't think it's bad if they're doing it outside...
As for the humping, Jackson humps his stuffed bear like CRAZY and he's not neutered yet but I have a feeling, the neuter won't change his humping LOL. |
