With a red collar and thick eyebrows just like his master Hagemaru, Pesu is always up for the fun this anime show brings. While extremely loyal to Hagemaru, Pesu can also be sarcastic, and particularly enjoys commenting on how poor Hagemaru’s family is.
Stingy just like the rest of the family, the pet can be selfish and tends to save everything he can. He has a crush on the dog Fluffy that appears on the show every once in a while. If the family ever needs him to do something, all they have to do is offer him a bone and he’ll go along with it.
Woodstock from “Peanuts”
Sidekick and best friend as well as, sort of, pet, Woodstock first appeared in the “Peanuts” comic strip in March of 1966 but didn't earn his name until June of 1970 – almost a year after the famous music festival that provided his name.
Apparently the bird began as a female, but once Charles Schultz came up with the name, the gender changed to male, since the name seemed more masculine. Schultz never divulged what kind of bird Woodstock is, though a few comic strips have ruled out eagle, duck, and American Bittern. Many assume he is a canary like Tweety Bird, but Schultz has never said yes or no.
Snowy from “Adventures of Tintin”
No matter who you are, if you found Tintin books when you were a kid, you fell in love with the globe-trotting reporter and his little white dog. A Wire Fox Terrier, Snowy goes by the name “Milou” in the comic's original French. His bond with his owner is strong, and the two have saved each other's lives multiple times.
While he prefers to stay by his owner's side, Snowy is often separated from Tintin. At the end of the day, they always manage to get back together. The dog was originally cynical in order to balance Tintin's optimism, but after the addition of Captain Haddock, Snowy became more good-natured.
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.
