“Pedigree Dogs Exposed,” the controversial BBC documentary that shed some much needed light on purebred breeding practices and the horrors they have produced, will get its first airing in the U.S. tonight.

The documentary looks at how many breeds have had their physical appearance so exaggerated they’re unrecognizable from a century ago, and it examines some of the breed-specific health problems that have resulted from breeders emphasizing looks over health when breeding dogs for shows.

The documentary led to the BBC dropping its coverage of Crufts, the UK’s equivalent of the Westminster Dog Show. The show, which led to some changes in Kennel Club and breeder policies and practices, airs tonight on BBC America.
