I've started long line training to reinforce my whistle training for recall. Also, following the advice in Pippa Mattheson's Total Recall book, I've started having Henry on and off the normal lead during our walk, whereas before he would have spent most of the time off. I've been doing this for about a week and his recall off the lead has got a lot worse than when he was off all the time. He goes further and takes longer to come back. This morning he completely ignored me for a good five minutes when I was asking him to come back. He looked at me and went the other way, and if I moved towards him, he moved further away. I did my usual trick of walking off at a brisk pace, which normally has him scampering back - nothing. His recall hasn't been this bad since before I started the whistle training.
Is this because I've been having him on the lead more so he doesn't want to come back to me? I've been reinforcing 'check ins' so he gets a treat for showing up by my side, and letting him go again after a recall, not always putting him on the lead, so he shouldn't assume he's going on the lead every time I call him back.
Is this change a result of the new regime or just coincidence, especially as he's coming up to that difficult adolescent age? It's depressing to go backwards when his recall was getting so very good.
