I have a three year old border collie, who is now learning 'open' work. Her heel work was fantastic on lead, but I find that now her off lead heel work is getting further and further away from me. She is quite a nervous dog, and wonder if this is the cause. She used to watch me, but not now. Can anyone give me advice as to how I can get her back to heel with me. She is food orientated, but I can't always use this on her. Other than the heel work, loves the rest of the open work
