Animal lover, comedian and presenter Alexander Armstrong opens the doors of his multispecies pet training school, to welcome miniature American shepherd dog Boomer and Stinky the pony, in the hope they can learn to retrieve and return a ringing mobile phone to their owner's hand. The star pet is Charlie the boxer, who sprung to fame by bouncing on a trampoline in a department store TV advertisement. The programme's trainers hit the road to help train Elvis the goat to be the star of a doggy agility show.
