I had a 3 pound Yorkie for 7 years that I just could not house break for nothing!! Sadly, I had to put her down last year!! I am ready to get a new small Yorkie. Im not sure if its possible to train a small Yorkie!! I need help is it possible to train a little dog like that? Do you think she will smell my other dog & urinate? Anyone with any suggestions please respond!! THANKS
