My 9 year old Bearded Collie goes on 4-6 walks a day and each walk is about 15-20 minutes. But when he gets towards the end of the walk he lies down in the middle of the street and won’t get up. A firm tug doesn’t work, we’ve tried a harness as well. If you pretend to go back the other way (away from our house) he gets up right away (but then he won’t turn around or he’ll just lie back down). He’s not food motivated so treats are useless.

Eventually he gets up but this could take 10 minutes of him just sitting there.

Any advice?

EDITED TO ADD: Thank you all for the wonderful suggestions! To clarify, he is not tired when he lies down. Bearded collies are notoriously stubborn and he just doesn’t want the walk to end. He goes on so many walks because that’s his joy in life, going outside and sniffing and marking. He’s more of an alpha in that regard and he cries at the door for a walk when he gets bored inside but on the walk he doesn’t have to go, he just likes being outside. But in Los Angeles we can’t just let him off leash. So the question was really just to teach him to stop fooling around with the lying down act which he thinks is funny. You can see in the second video he often puts one paw around the leash to make it harder to pull because he’s smart and devious. But we will try some of these suggestions so thanks again!
