My dog is ten months old. We have always had a problem with housetraining her because she doesn't tell us when she needs to go out. She understands that she is supposed to go outside, but if we don't get her out in time, she has no problem with going on the floor. And now that she's older, it's just irritating. We know she can hold it for upwards of six hours during the day, but when we're home, she pees on the floor if we don't take her out. I think at least four months ago we put the bell on the door. At first, we would physically take her paw and ring the bell and praise her. Once she got that, we would tell her to ring it and she would. Now, we stand by the door and sort of look like its time, without saying anything and she does it. But she will not do it completely on her own, no matter what we do. She gets treats when she rings it and treats when she goes potty outside, but shes still having accidents at least every other day. It's so frustrating! We can't trust to leave her alone in a room because if she hasn't just peed, she might just go. I wish she would make an attempt to tell us first, but its just not working out. Good luck with your dog
