I saw a few posts down that this dog isn't neutered. Unfortunately at 4 yrs old, he's probably lifting his leg and marking. He will probably NOT stop if he gets neutered now because of his age. I guess you could try those belly band things.
Ours is a male, he doesn't "do" bows, but he owns plenty of clothes
We have a crate, but he usually sleeps in our bed.
Good luck
