It looks like my Chloe is back! Her speed caught me off guard. She has been off for 4 months because of an injury. While she comes back, Scout's drive and motivation deteriorating so I am going to have to back up a step or two. He seems lost. He usually runs and drives hard through the weave poles. I can usually tell he is 'on' when the weave pole base moves.
