Clovis, my 5 yo neutered male Basset Hound began marking inside by urinating on things with new smells. This started after he attended a doggie daycare where he could pee on cement floors anytime he wanted to. However, when he came home he couldn't/wouldn't differentiate between my house and daycare. He hasn't gone to daycare for about 6 months, but he continues to mark inside if I leave a box or bag on the ground that has a new smell. Therefore, I've begun putting him in a crate when I have to leave, and keeping an eye on him when I'm home. He has a doggie door and frequent access to the outside, and he sleeps with me all night without moving so I know this isn't a physical problem. I've searched everywhere for a way to break this marking but have come up with few ideas. Any thoughts? Thanks.
