We have been working on recall with our 1 year old rescue dog for the past 4 or so months using a long line. She got to the point where I could let her off in certain "safe" areas with no roads or other dogs nearby and she would come back reliably. However, took her out yesterday and she refused to come back. She would come towards me, but not close enough for me to catch her and put her on the lead. I call her back frequently on walks just for a treat so she doesn't always associate being called with going back on the lead, but she seems to have realised that that is what is going to happen at some point on the walk. She's back to training on the long line, but any other ideas?
