Across Australia, thousands of pet dogs are dumped by their owners. The animals quickly recover their survival instincts, to become at best nuisances, at worst dangerous killers. In the country they form packs and attack livestock; in the city they roam the streets or surbuban bushland. It is not their fault, but the fault of irresponsible, uncaring humans, and this program looks at the lives of two people who have to deal with these unwanted dogs - both animal lovers who have the unpleasant task of doing society's dirty work. In the Casino district of New South Wales, Rural Protection Officer John Friend tries to cope with dog packs that are decimating local cattle herds; and in Sydney the manager of the RSPCA's animal shelter, tries to find a humane solution to the problem of the 14,000 dumped dogs that arrive on her doorstep every year.
