dont use a piddle pad because that encourages them to pee in the house , i would try crate training.use vingear where she has gone pee never anything with ammonia because urine has it in it and she will smell it and it will encorage her to go pee there,vingear dogs hate the smell of so they wont go pee there.i used to work in a vets office and know alot about dogs
ohh and i am so sorry t hear about the fire
So sorry to hear you lost your Yorkies in a fire. How sad.
I agree with Kathie about the piddle pads and using a crate for training. You have to remember you have a kennel dog and she has to be trained to a house now. Add to that, for some reason, these small dogs can be so hard to house train. I had Yorkies years ago and had a male (neutered) that just would not stop marking my dining room table.
