Hi all. So I have a 1 year old Great Dane who has started to pee in his sleep. It has happened twice now in the last few weeks and he doesn't even realize it has happened. He isn't neutered and has always had a sensitive stomach but this is something completely new. He has been trained to go outside for awhile now and I don't know what his problem is. Any advice or suggestions? I am going to call his vet tomorrow but I was just wondering if anyone else has experienced something similar.

Wow! That's a big dog. I don't have any kind of experience or advice for you, but do tell us what the vet says.

Vet visit is definitely in order. That's not even a case of housetraining issues...that's either UTI or perhaps neurological. Please let us know what the vet says.

I agree with the other posters. It could be health problem and not behavioral. It could be his urinary tract.
