The series is action packed, and really fun to watch. All the characters such as Holmes, Watson, Mrs. Hudson, and Prof. Moriarty were made into dogs. Holmes is a lot younger and more active than in the novels (he drives a car and does a lot of car chases). Mrs. Hudson, now a 19 year old widow, gets a piece of the action.
It was made as a joint project between Tokyo Movie Shinsha and an Italian TV station, RAI, in 1981. Hayao MIYAZAKI directed 6 episodes (3-5 and 9-11), but the production was put on hold due to a copyright dispute with Sir Arthur Conan Doyle`s estate. In 1984, after the copyright dispute was finally resolved, Tokyo Movie Shinsha decided to make more episodes of Holmes and to air it as a TV series as originally planned, with totally different staff members from the first 6 episodes.
