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.
Jake the Dog from “Adventure Time”
What do you mean he isn't a dog? It's right there in his name! Okay, fine, dogs can't normally talk, change their shape to anything they want, or make bacon pancakes, but here we are anyway.
Not exactly a pet, Jake is still Finn the human's best friend and constant companion, minus the few episodes where they became at odds. He's wise, supportive, and guides Finn through all the troubles he comes across, while also being a good husband and father at the same time. Really, we should all try to be Jake, even if we can't change our shapes to whatever we want.
Courage from “Courage the Cowardly Dog”
Part comedy and part horror, “Courage the Cowardly Dog” was a standout show on Cartoon Network during the nineties. Courage constantly kept his owners, an irascible farmer and his kind-hearted wife, safe from monsters, ghouls, and other terrifying things.
Courage is, as the show's title notes, quite scared of everything, but he has to constantly overcome his fears to battle the monsters. What could be better than a pet that puts it all on the line to protect his family? The show ran for four seasons, showing us ghosts, aliens, mummies, and plenty of other creepy characters.
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.
Dogmatix from “Asterix”
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.
