This is proper a mental challenge for your dog.
Most of the dogs probably know how to circle a street lamp or a tree if he has gone around on the different side than the owner (knows where he got there and where to get back).
But when the owner wraps the leash around something, the dog doesn’t know which way he should circle and he need to figure that out.
You should start this game in a quiet place without any distractions and in the first time you should only wrap the leash around once so the dog doesn’t panic.
