I just got my yorkie, princess, and she will only go on her puppy pads indoors. That is good, but I really would like for her to learn to go outside. I have already tried putting her puppy pads outside where I want her to pee, but she smells it and eventually will lay down on it like it is a bed. I have only put them outside for a day. Should I give it more time? Any other suggestions?? Thank you!
