Hello everyone.. I have a 3 year old LH weimaraner. She is a great dog except she still has accidents in the house but only at night. The problem is that she has NEVER whined, even when she was a puppy. My husband and I don't know how to get her to let us know she has to go out at night. Our other dog will bark if she needs out but the 3 year old is not a vocal dog. She paces the house and if we don't wake up to that she goes on the floor. We have tried using a bell on the door but that doesn't wake us up either.. I am against kenneling her again at this age so any other tips would be great!
