So I've noticed a few times that Tucker leaks some urine when he's sleeping. He doesn't do it that often (from what I've seen), but his bed always smells like pee. I washed it last night and this morning I can already smell the slight smell of it (maybe I'm looking for it by this point). He's around 13 months old and use to submissive pee a lot and still pees when he gets really really excited. Do they grow out of leaking? Do I need to do anything to help him stop? Is it something medical? He's been to the vet more times than I've been to the doctor and he's always healthy except for minor allergy issues. If I keep washing his bed the way I have been it's going to fall apart, and large dog beds aren't cheap.
