Ранта́нплан: Верный, но не слишком умный пёс Лаки Люка

Fictional Lucky Luke dog

Rantanplan (ʁɑ̃tɑ̃ˈplɑ̃; alternatively spelled Ran Tan Plan and Ran Tan Plan) is a fictional hound dog created by a Belgian cartoonist Morris and French writer René Goscinny. Originally a supporting character in the Lucky Luke series, Rantanplan later starred in self titled series. Rantanplan is a spoof of the male German Shepherd Rin Tin Tin. In the Turkish translations of the series, he is indeed named Rin Tin Tin. English versions of the books have renamed him "Rin Tin Can" and "Bushwack" in the 1983 Hanna Barbera animated television series Lucky Luke, as well as "Rintindumb" in the French comedy animated television series The Daltons produced by French animation studio Xilam.

The character first appeared in the earliest panels of the story Sur la piste des Dalton, published on 4 February 1960 in the Franco Belgian comics magazine Spirou, and later as an album in 1962. The character remained a fixture over a long series of Lucky Luke publications, resulting in a series of its own spin off publications starting in 1987. Ten years after the death of Goscinny, for the production of the Rantanplan series, Morris collaborated with scenarists such as Jean Léturgie, Bob de Groot and Vittorio Leonardo.

Rantanplan is a prison guard dog, often tasked with watching over the Daltons or assisting Lucky Luke track them down when they escape. However, he is unable to understand this and often mistakes Joe Dalton, who hates him psychotically, for a beloved owner. As well as being stupid, Rantanplan is extremely slow and accident prone. However, he is usually very good natured and loyal. Like Averell Dalton, he has a huge appetite and will devour everything put in front of him, whether it is food or not, which has ranged from bars of soap to dishwater. Lucky Luke's horse, Jolly Jumper, a very intelligent animal, holds Rantanplan in contempt, regarding him as one of nature's great mistakes.

In 2006, French animation studio Xilam produced an animated television series of Morris's Rantanplan stories in 90 second episodes, broadcast on the French television network France 3. It is broadcast on Canadian television network YTV in Canada under the name Rintindumb, and was distributed by Warner Bros. Television. It featured the voices of Maurice LaMarche and Rob Paulsen. It was on a Finnish family friendly streaming service Toons. TV until 2015.
