Just had a very rewarding training day with Dylan that I have to share with someone. Huge advances- thanks to all the above advice. Bought a long line from PAH and went off to park with bag of livercake to hand. I just let him career off as normal, giving him a sniff of livercake before he left. He stayed very close and every time he went too far I called him back. Sometimes he got livercake, sometimes just a big fuss and a cuddle. Another dog came towards us off lead, I let him run off towards him, I loosely picked up the long lead and followed him over, owner was okay to let them play. so we chatted about the training, I called him, gave livercake and off we went.What a difference that I had control at the end of the long line in case something went wrong with the other dog,but Dylan was unaware that I was holding it. Again when we passed the footballers, he careered towards them but came the second I called him he came back-I had picked up the long lead just in case but didny need it- amazing!! So he has complete freedom, I have peace of mind that I have control if he takes off or meets another dog. We had a lovely walk, completely relaxed, what a difference, thank you. Livercake now reserved for recall and training class only, will also try the tuna bread.
