I adopted a 4-year-old female Miniature Pinscher from a shelter last Tuesday. I am pretty sure that she was a breeder at a puppy mill. In the five days that I've had her, she hasn't peed or pooed outside once, even though I've been following all of the rules for a puppy mill dog--walking her on a schedule, keeping her leash on in the house so she gets used to it, etc. Luckily, she's already figured out how to pee and poo on newspapers/potty pads, but she'll only do it if no one is watching. I just need to know what I can do to get her to do her business outside!
