Caillou and his family are heading to the tobogganing hill! What fun it is to climb the hill and race down surrounded by people having a good time. Caillou is curious when they see a sled dog and his master giving a sled show on the premises. Caillou watches in wonder as the dog obeys the vocal commands. He’s even more impressed when he gets to ride the sled with Rosie and the dog listens to him!
