My rat terrier will do nothing for treats of any kind. I am simply trying to teach her basic obedience skills, like sit and down, she can stay pretty well and she always heels nicely even off leash like I normally walk her. She will take treats from me and eat them from my hand but If I ask her to do something for them she cowers and runs off if I don’t have a leash on her or she simply avoids me and the treats. I think part of the problem is that at the puppy mill where she was rescued from used food and things to get the dogs close enough and she’s associating that with me using food to get her to do things. I’ve tried working with her with my other dog Gizmo who I trained the same way she’ll watch him but seems nervous to copy him in getting a treat. Any ideas why she does this or what I can do to help her and possibly work on her basic obedience skills?
