Sarah-Jane takes two young friends and their dogs to a dog agility class for the first time. Go-Joe meets his friends Ellie and Harvey, who are grooming their dogs. When Sarah-Jane joins them, it gives her an idea. She takes them all to get active with their pet pooches at a dog agility course! The children learn how to race with their dogs around the course, sending their canine friends through tunnels and over hurdles and other obstacles. It's great fun and great exercise, whether you are on two legs or four.
