8 yr old blonde lab is deaf and peeing in the house

Question
QUESTION: We recently adopted a blonde lab who is partially to mostly deaf. She has a great personality, very loving. She was a puppy mill dog, unfortunately she was a breeder and you can tell she had too many litters. Her teeth are ground down and she has marks on her legs from being caged all the time. I have never caged an animal. We got her from a friend of a friend who had rescued snuggles from the puppy mill and had her for two years. They said they didn't have the time for her anymore. They also didn't cage her. I believe they also had problems with her going in the house, though they didnt disclose it. The problem we are having is she keeps peeing and sometimes defecating on the bathroom floor. She does fairly well during the day when we are not here, sometimes there are accidents. Normally this happens at night. We take the dogs out (we also have a 4 yr old male black lab) at night before we go to bed. Normally I can hear her collar jingle in the middle of the night and I get up to let her out. Sometimes though I can't hear it and she pees on the bathroom floor. I don't know what to do. My fiancee wants to get rid of her, I love her and don't want to give up on her, she's already had a hard life. Please help me.

ANSWER: There is no quick, easy solution to this.  Take up the water at 7 PM.  Before bed time, take her out and make her walk around.  Give her a treat for eliminating.  That may help some, but I can't promise it will be enough.  

There are so many dogs needing homes, I hate to see the fine people that give such a dog a home have trouble.

QUESTION: Thank you for answering! We do take up the water at 7pm. Last night we left them out at 12am (she did pee outside, which she normally does do) and when I heard her jingle at 5am she had already peed on the bathroom floor. I guess I'm confused that she can go all day at least 9 hrs, for the most part, without accidents, yet at night, she can't and its much less time between going out. My saving grace is the bathroom floor is tile, so its not hard to clean up. I'm wondering if I closed the bathroom door if she would start going elsewhere in the house? Why would she target the bathroom? I was also thinking of buying those puppy mats that the stores have for puppies to pee on in the house. However, I'm worried that it will keep her going there and might even attract Scamp (the other lab) and possibly even my cats to pee there. Your opinion?

I give the dogs treats when I get home from work if she doesn't go in the house. I also do that in the morning if she doesn't go overnight. Am I doing this backwards? Should I give her a treat everytime she goes out to pee instead of when she doesn't pee in the house?

Answer
I discourage the pads for housebreaking thinking it only confuses puppies.  Still, it might work in this case.  While, yes the other dog might start using them too, I think the cats would stick to their litter box.  You might ask somebody with more cat knowledge about that.  

I highly doubt she would connect not getting a treat with having had to urinate in the bath room.  The immediate treat for urinating outside should be much more effective.  

Why the bathroom?  Maybe because that is where you go.  I am afraid if you shut the bath room door, if she has to go, she will be forced to go elsewhere.  It occurred to me you could use a motion sensor in the bathroom at night.  Maybe as simple as one of those frogs that ''ribit'' when you walk near them.  If you hear her collar sometimes, you must be a light sleeper.  The frog could be enough to get you to her in time.  

The hard surface floor is great.  We are getting our regular fall new puppy next Saturday.  About a dozen puppies ago, we ripped up the carpet in our family room and kitchen and refinished the hardwood floor with an industrial urethane.  It laughs at urine and toenails.  A quick sponging and we are done.
