My pup started off really well at dog training, we were getting lots of positive feedback etc and he was really enjoying it too and obviously getting a lot from it because he'd take himself off to bed as soon as we got home. The last couple of weeks however have been different, I don't know if it's because the ground was frosty last week and wet this week but he just refuses to do 'down'. He'll sit and stand and do everything else, and he did behave better this week than last but still he refused to lie down. It's getting frustrating because he'll do it at home all the time and will do it when we have visitors (both human and other dog distractions). Does anyone have any tips on what I can do to help him to lie down next week? Thank you
