Guessing from the lack of reviews, I will assume this series was a sole phenomenon in Portugal, and maybe Spain? The Dogtanian "Dartacão" opening song was such a hit here that every kid and adult knew how to sing it or as least hum the melody. The opening YouTube video in Portuguese has 712,378 views, and it's only one of the many ones. The series was created by Claudio Biern Boyd. The 26 episodes were produced in 1981 by the Spanish international BRB and the Japanese Nippon animation. It's a faithful adaptation of Alexandre Dumas' novel "The Three Musketeers", although it has some different details such as theprotagonists being dogs or the protagonist's beloved being called Juliet instead of Constance. One can be sure that this series inspired many cartoons and was highly influential to the now famous "Beastars". Nah, just kidding.

This series premiered in Portugal in 1983 on Saturday mornings. It quickly became a success, being repeated several times in a public main channel. In the beginning of the 90s, it was repeated and also on another private channel in 1995.

All in all it was a light-hearted and very entertaining series with a classic good vs evil theme.
