We have a 7.5 month old cocker. He’s been great off the lead for ages and awesome recall with a whistle. Suddenly this week he’s refusing to come. He’ll be great and play games all the time then at the end of the walk he must sense it’s ending and he just sits refusing to come to me. If I go to home he runs, if I turn my back he will sit again but never close enough to grab him. I pretend the walk isn’t over but he knows. I take him for an hour early afternoon but need to get back home for meetings. Today I was 45 minutes late because he absolutely refused to come close enough to get the lead on him. I’ve ordered a long line but that won’t teach him to come just means I’m reassured he can’t play games. I’m gutted my lovely dog who was fun to walk has changed in one week. What can I do or is he a lead dog now?
