Adult dog peeing in the house overnight...

[rhoernke]

Any suggestions for my little girl? She is an adult dalmatian, and she was spayed prior to getting her. She has been in the house for 9 months without a hitch or accident. Over the last week, she has started peeing in the same location in the living room during the night. She has no accidents during the day while I'm at work, but has gone potty in the house 6 out of the last 9 nights. No signs of stones in her urine, and she is on a good diet recommended by the rescue we got her from. Any suggestions?

Does she pee while sleeping, or does she pee deliberately? (i.e. does she squat?) Is she wet at all when she wakes up? I'm just wondering if this might be spay incontinence, which is caused by low estrogen levels, which weakens the bladder muscles. If it is spay incontinence, she'll sort of leak as she sleeps.

No leaking, she gets up, and leaves the bedroom. She sleeps in the bedroom, but goes just outside the bedroom door to go pee. I can't really tell when it happens, but she stays in the bed 99% of the night, getting out at some point, then coming back on to the bed.

hmm... What has the vet said about it?

I am taking her to the vet in two days... (off of work) At first it seemed like a behavioral activity, and not a medical problem. I thought I would try researching this through other dog-owners in the meantime.

I think it might be a medical thing. Just because it's unusual behavior for her.
