My dog just staring marking his territory, and he's doing it inside the house! Is there any way to stop this? Or is there any way to set up specific spots where he can do it? We can't take him outside because it's too cold for him (he's a chihuahua). Also, he doesn't like walking on the leash, so we can't even walk him when it gets warmer. Is there anyway to get him to like it? He doesn't respond to treats when he's upset about something, so I can't train him with that. Lol, any help would be appreciated!
