In 2008 Pedigree Dogs Exposed lifted the lid on the true extent of the health and welfare problems faced by pedigree dogs in the UK. The startling expose of harmful breeding practices generated a massive reaction from the public and from those involved in dog breeding. Now the programme's producer Jemima Harrison returns to explore what has happened since she made the original film. Deeply affected by the issues that she uncovered, Jemima has become a campaigner on dog welfare. In this programme, she takes a personal look at the positive changes that have been introduced since the first film and investigates areas of continuing concern, particularly among breeds like the Pug, the Bulldog and the Cavalier King Charles Spaniel. Jemima hears from dog breeders and a range of experts, many of whom express grave worries about the future of some of our best loved breeds.
