My golden, Monty, is the most stubborn dog ever. Every time we go for a walk and get close to home he will stop and lay down on the grass/sidewalk/road! He is 80 lbs so picking him up is not an option. I've tried dragging him but he wont budge and I don't want to hurt him. The only way I am able to get him up again is by shaking a bag of treats but I don't want him to think I'm rewarding him for this. How can I train him NOT to do this? He is impossible and I dread walking towards the house!
