It is the early 17th century in France. Dogtanian is a simpleton countryside dog that aspires to join the ranks of the Royal Musketeers – the personal guard of King of France Louis XIII and his Queen, Anne of Austria. Thirsty for adventures, he never looks back to an opportunity to save the day or his beloved Julliet. Together with his friends Sandy the horse; Planchet the servant; and the three muskehounds Athos, Porthos and Aramis; Dogtanian will fight Cardinal Richelieu's evil plots to seize the power of France. However, his goal won’t be easy, as Cardinal Richelieu has powerful allies that will do anything to defeat the noble musketeers including the Treacherous Milady, the ever-fleeting Count Rochefort and the clumsy Captain Widdemer.
