Also known as "Dogtanian and the Three Muskehounds", this animated TV series was memorable in the lives of many people when they were children, including me.
Basically it is the legendary story of D'Artagnan and the three musketeers, but because this is an animated version, it has a charm of its own and a certain nostalgia feeling I can't explain. Being an animated version, this one is naturally a version with anthropomorphic animals, in this case dogs (as you can see by its title).
This is a classic animated TV series perfectly suitable for children, being charming, sweet and timeless, unlike most today's cartoons which are ugly, uninteresting, pretty violent, almost painfully noisy and often contain destructive humor. This animated TV show is from another time, a gold generation which was the very best to be a child and when everything was totally different.
The opening song is absolutely adorable and timeless. Put it this way, it is a lovely song. So memorable that once you hear it, you'll never forget it for as long as you live.
Although the popular story of D'Artagnan and his three musketeers is french, this is actually a Spanish production, which manages to be loyal to the french story yet has a characteristic Latin enchant, resulting in a great combination of both.
D'Artacan (or Dogtanian) lives many adventures with his partners and friends (the 3 muskehounds), but he has also an original and humorous little friend: a very talkative and energetic anthropomorphic mouse that speaks with a strong Latin accent. But I can't remember the mouse's name...
I always found Milady (an anthropomorphic cat) to be a strange character: very mysterious and enigmatic. She's the kind of character that at times seems to be a brief friend, but is also a troublemaker for Dogtanian as she often hypnotizes him.
In conclusion: this is a cartoon to have fond memories of.
