Hello. I just purchased my first two minis! They are both about 50 lbs underweight and were not taken care of very well. One is super sweet and friendly. The other one was abused and was previously purchased from an auction from what I was told. She is skittish and runs whenever I try to approach her. I was able to catch her by using carrots , put a harness on and walk her with a lead rope. How do I gain her trust and show her I'm not going to hurt her?
