As soon as Walt Disney read “The Hundred and One Dalmatians” by Dodie Smith, he knew right away that it was the kind of thing he could make into a movie. In 1961 it happened, and the film follows the book closely.
As Pongo and Perdita’s owners fall in love, the dogs do the same, eventually having fifteen puppies. After the evil Cruella de Vil steals the dogs away, the adult dogs don’t stop until their children are safe. Some people think that Perdita and Pongo had every one of the 101 puppies, but eighty-four of them were adopted after being rescued from Cruella.
Mr. Peabody from “Peabody's Improbable History”
Mr. Hector J. Peabody is the world's smartest being. He's also a dog, a beagle to be precise. One day he became lonely and adopted a young human boy named Sherman. That's right, this dog isn't a pet – he's the owner! Pulled a sneaky on ya.
Peabody can speak eight languages fluently, has worked for the foreign service, and is even called the “Woof of Wall Street.” He and his boy Sherman go on plenty of fun adventures using a time machine, and despite the numerous inaccuracies, kids not only got a laugh but managed to learn something, as they watched Peabody and Sherman fix the problems with history.
Pluto from Disney
Disney began with the sensational six: Mickey, Minnie, Donald, Daisy, Goofy, and Pluto. Of the six, Pluto was the only one who was anthropomorphized like the others and still retained the dog-like qualities. This despite his owner, Goofy, also being a dog. It's very confusing.
The pooch got his start as an unnamed bloodhound from the 1930 animated short “The Chain Gang.” A few months later he made another appearance as Minnie Mouse's dog Rover in “The Picnic.” He didn't become Pluto – named for the planet that had just been discovered – until 1931 and “The Moose Hunt,” taking his place at Mickey's side. He's been a star ever since.
Dukey from “Johnny Test”
Johnny Test received Dukey as a gift on his eleventh birthday, and before long Johnny's mad-scientist sisters had used him as an experiment, giving him the ability to talk and walk on his hind legs. As Johnny Test uses his sister's science projects to help with one scheme or another, Dukey often acts as the voice of reason – though he also usually ends up joining Johnny after being tempted by a treat.
Dukey gets pretty stressed out by all of the dangerous things Johnny does, though it always turns out right in the end. His memory is quite good, and he uses it to remind Johnny of the more dangerous things that have happened.
Dug from “Up”
Dug is a golden retriever who belongs to Charles Muntz in the Pixar movie “Up,” but it isn't too long before he changes allegiances and starts helping out Carl and Russell. He's able to speak and understand English thanks to the special collar that Charles Muntz invented.
Despite looking older, Dug acts much like a puppy, with boundless energy and excitement about each and every single thing. During the incredible adventure that the other characters of the film go on, Dug is a constant companion and help, getting everyone home safely. Dug immediately idolizes Carl and sees him as his new master. By the end of the film, he is a father with something like twenty puppies very much like him.
