A page from Rally's ride
Rally's book starts with a suitcase and a corgi who refuses to be left behind. Whatever train your Cavalier King Charles Spaniel can ride, packing its own small bag (water, a towel for the floor, a chew) makes the trip feel like Rally's. His packing page is in our free coloring and activity pack.
