For thousands of years dogs were working animals and not just pets, carefully bred to hunt, guard, herd or retrieve. Now these finely-tuned instincts are turning working dogs into problem pets. This film follows two dogs, a bloodhound called Holly and a bearded collie called Herbie. Neither dog has done a day's work in its life and both face an uncertain future in rescue homes because they are so out of control. In a unique experiment, Holly and Herbie are taken to professional trainers to see if they can be put back to work sniffing out criminals and herding sheep, and given the second chance they deserve.
