2 year old Chihuahua absolutely hates a leash. I have worked with her on and off since I brought her home. I worked with her everyday for a couple weeks when she first came home to us but was beside myself with frustration. She acts as though it is going to hurt her. It is a light weight, small leash and it clicks onto her collar, so it's not as though it's a horse training rope. I put it on her and she sits and shakes horribly. I tried to walk while holding the leash and she jumps backwards like she is in a hot frying pan. This happens every time I put the leash on her. I cannot afford to take her to a professional trainer, but am at my wits end. Just looking for some helpful hints or ideas. Thank you!!
