Katts and Dog is a French and Canadian-produced television series which ran from 1988 to 1993. It was known as Rin Tin Tin: K-9 Cop in the United States where it originally aired on CBN Cable/The Family Channel and Rintintin Junior in France on La Cinq. CTV broadcast the series within Canada.
When the episodes were filmed the dog’s name was “Rudy”. When the series was aired in the U.S. and France, the name was dubbed as “Rinty” to go with the new title. However, some episodes of Katts and Dogg have the American dubbing where "Rudy" is called "Rinty" throughout the episode. The episode Hit and Run is an example of this.
When the series went out in Britain, it kept the title Katts and Dog, but the dog's name was changed to “Rinty.”
The show is about the life of Canine Officer Hank Katts and his canine partner who fight crime and the forces of evil. The show’s early episodes begin with Hank just finishing up Police Academy. Later on, it shows the first meeting between Katts and Rudy/Rinty. It also shows the life of Hank’s nephew, Steve, through the death of his mother and his adoption by Officer Katts.
A 1991 TV movie had Officer Katts and Rudy visit Paris.
