The Plague Dogs is a 1982 animated film based on the 1977 novel of the same name by Richard Adams. The film was written for screen, directed and produced by Martin Rosen, who also directed Watership Down, the film version of another novel by Adams.
The film's story is centered on two dogs named Rowf and Snitter, who escape from a research laboratory in Great Britain. In the process of telling the story, the film highlights the cruelty of performing vivisection and animal research for its own sake (though Martin Rosen said that this was not an anti-vivisection film, but an adventure), an idea that was only recently coming to public attention during the 1960s and 1970s.
