This tiny white terrier is the perfect companion for a huge Gaulish warrior – they even have the same response to danger (attack). Dogmatix – known as Idefix in the original French – first appeared in the fifth Asterix book, “Asterix and the Banquet,” which came out in 1965.
He’s the only animal character among the main characters of the series and is often relegated to a minor comedic role. Asterix and Obelix would often get into shouting matches about whether or not Dogmatix should join them on adventures. He, like the rest of the characters, has drunk the magic potion that makes the Gaulish warriors so strong.
Puar from “Dragon Ball”
Though appearing to be a strange combination of a cat and a rabbit, Puar is neither. With an unwavering love for Yamcha, the two appear early in Goku's journey in the original “Dragon Ball.” Though not as skilled at fighting as Yamcha (who himself is quickly left in the dust by the stronger characters), Puar's ability to transform into a number of creatures proves invaluable during the many fights of the series.
Puar can also levitate, and before the main characters learn how to fly, it's incredibly useful. The character's gender has never been truly nailed down since the voice actors changed a few times, but Akira Toriyama considered the character male while writing the manga.
Shiro from “Crayon Shin-chan”
Also called Lucky or Whitey depending on the dub you're watching, Shiro (meaning white) is a fluffy Maltese puppy that child Shin-chan found in a cardboard box in an early episode of this cute anime series.
Despite being a beloved member of the family, Shiro is often forgotten by his owner, due to Shin-chan's hectic nature. He's developed a talent for scavenging since his meals end up sometimes being few and far between. He is mostly dog-like, but a few human elements are present, such as being notably responsible and incredibly careful. In a number of specials, Shiro can speak.
Max from “How the Grinch Stole Christmas”
While the Grinch in his many reincarnations always steals the show, his faithful pooch Max is always there to help him out. At the top of Mt. Crumpit, even the surly Grinch has space in his shrunken, shriveled heart for a pet.
While a villain's pet usually lands in the sycophant role, Max is kind-hearted, warm, and affectionate, whether or not the Grinch likes it. His goodness is in stark contrast to his green-furred owner. Once the Grinch learns the truth of the holiday, and his heart grows three sizes, Max is fully on-board as they return all the presents, trimmings, and roast beast.
Muttley from “Wacky Races”
Though not the kindest dog, Muttley was always there to help his owner, the villain Dick Dastardly, try and cheat his way into the winner's circle. Even though he helped set the schemes up, he took great delight in watching them blow up in Dastardly's face, always delivering his memorable wheezy laugh when it happened.
Despite being one of the lesser-known animals on this list, his impression of the dog sidekick can't be understated – how many even on this list roll their eyes and go along with what their masters want? That's all thanks to Muttley.
