First off, it's not spite. I don't believe dogs are capable of that. He is probably going there because he smells it from the past. You need to get a good enzyme cleaner and maybe a black light to be sure you get all of it up. Even when you can't smell it, he can. And if he is marking and it has become a habit, you might want to crate him for a little while at night until he gets past that. They even have nice play pen sort of crates so you don't have to feel like he's in "jail". good luck! |
