My dog spent six years in a puppy mill. She never had a name, much less any positive interaction with humans. My first step was to build her confidence. I praised her for everything from sneezing, looking me in the eye, or voluntarily coming into the room I was sitting in. “Good Girl Rachel!” Turkey Bacon helped a lot and I cook it just for her, hid pieces around the apt and when she found it...”Good Girl Rachel!” Turkey bacon and praise. 6 months later she plays and snuggles. She has a long way to go and still hates being outdoors, I take bacon outside with us but she is not ready to conquer the outside world yet. She does continue to progress. If I can do it, you can do this.
