Rugby and I occasionally need to go back to our circle of gloves to keep it fresh in his brain. We put our 11 gloves (white, green and brown) 15ft. from Rugby in a circle. We stay in the middle pivoting around and I send Rugby to random gloves until they are all gone. Usually when we run out of gloves we move on.
Today, the first one wasn't so hot so we did it again. But not before we spent some time defrosting in the car! Brr!!! Rugby wore his sweater for the second round.
