7 mo. old schnauzer urinating in beds

Question
I have had my 7 month old schnauzer since he was 8 weeks old.  He is house broken.  Last week, when I was getting my children ready for bed, he urinated in the floor.  When my 6 yo. saw, she yelled for me.  The dog then went onto my bed and finished.  Last night, he urinated in my 6 yo. bed.  This morning he got into bed with me.  When he got out of the bed, I rolled over into urine.  My husband yelled at him and he finished in the hall.  Help!!!  I love this dog and do not want to find him a new home, but we can't keep this behavior going, either.

Answer
Hi Casandra,
I think I can help you, but I'd like to get some additional information from you.  First, is your dog neutered yet?  Where did you get him, and at what age?  Has he gone to puppy kindergarten or any training classes, and, if so, what methods are you using?  Do you have a crate, or was he crate trained in the past?  Have there been any recent changes in your household, such as a move, or a new baby, new pet, new furniture, etc.?
If this is sudden behavior, and you really do think he's house-trained, my first advice would be to have him checked for a urinary tract infection.  That way, if he's negative for that, we can assume that it is, perhaps, a behavioral issue, and deal with it from there.
