With yellowish fur and brown jowls, Shishimaru is quite the recognizable dog. He’s a bit overweight since he loves eating, but most of his loyalty goes to the brothers Kanzo and Shinzo – though, of the two, Shinzo is his favorite.
Most of the time this ninja dog goes on adventures with the brothers. He’s often lazy and would rather stay at home, but his desire to be with his friends usually wins out. With an ability to change his shape slightly to fit a need, he’s often a useful tool for the brothers. He can also, for some reason, turn into a fireball.
Zero from “The Nightmare Before Christmas”
Despite being a ghost dog, Zero acts very much like any regular dog. He loves fetching bones (that are part of Jack Skellington's body). He's also quite perceptive, showing reservation when Jack develops an unhealthy obsession with Christmas – vindicated when the obsession turns out to be a disaster.
His primary concern is Jack's happiness, and so even though he didn't like the obsession, Zero helped out Jack, trying to guide him in the right direction. With a glowing jack-o-lantern nose at the end of his long snout, he ends up taking the Rudolph spot as Jack masquerades as Santa Claus.
Nermal from “Garfield”
Making his first appearance in 1979, Nermal immediately started to get on Garfield's nerves. He was often mistaken for a female due to his long eyelashes and the feminine tone of his voice. However, this is because Jim Davis tends to give young characters long eyelashes.
Nermal often intentionally annoys Garfield and Odie, prompting Garfield to try and mail him to Abu Dhabi. Much to Garfield's dismay, Nermal often shows up on Garfield's birthday. He proclaims himself the cutest kitten in the world, and despite annoying Garfield, sees the bigger cat as his best friend. With a mixture of devious brilliance and cuteness, Nermal is a one-of-a-kind kitty.
Abu from “Aladdin”
Maybe less of a pet and more of a best friend, Abu was always on Aladdin's shoulder throughout all three animated movies and the television show that Disney produced. Whether he was in his natural primate form or, as in the first film, had been changed into an elephant, he was on Aladdin's side through thick and thin.
With quick hands and a quicker mouth, Abu helped Aladdin steal the food they needed, though he wasn't anywhere near as altruistic as Aladdin when it came to handing food out to those even less fortunate. He was also pretty gobsmacked when Aladdin got hearts in his eyes for Jasmine.
Snoopy from “Peanuts”
First appearing more than seventy years ago in 1950, Snoopy was inspired by cartoonist Charles M. Schulz's childhood pet, a beagle named Spike.
He's a loyal (mostly) pet of the round-headed Charlie Brown, but he is much more than that. He wowed kids with his tales of being a World War I pilot, worked on his pulp novels at a typewriter, had a blast decorating his famous dog house with Christmas lights, and much more. He's famous around the world – Tokyo even has a Snoopy Museum. Snoopy is the pet we wish we had.
