Action Pups!

A four-month-old border collie gets carried away during a first taste of sheep herding, while two seven-month-old Siberian huskies undergo training for competitive sled racing in Gloucestershire - without any snow to be found. On a farm in Fife, a litter of springer spaniel-poodle crosses discover the world around them, while a city-dwelling dog savours a meal made to build muscle.
