Best 3-Letter Dog Names

First making an appearance in the Pixar movie Up, Dug is a large, lovable Golden Retriever. What makes him so unlike any other Lab, let alone any other dog around, is his special collar, which translates his thoughts into English.  As if that wasn't enough, Dug is very much a puppy. He's joyful and clingy, loving and silly – all the things that make puppies so enjoyable. Perhaps this is why Dug couldn't possibly be contained in one movie. He also appeared in Dug's Special Mission, and George & A.J., two Pixar short films based around the movie Up, and its characters. 

Another famous dog with a 3-letter name is a classic – Ace! This German Shepherd was actually the third member of the Batman and Robin dynamic, after his former master was kidnapped, of course. In order to save his beloved John Wilker, he raced around in the Batmobile, took on thugs head-on, and eventually helped Batman and Robin save the man. He even wore a batmask and emblem, courtesy of Robin, so that the dog would not be recognized and taken prisoner. By the end of the journey, Ace the Bathound had returned home with John Wilker, but not before being told that the position of Bathound is always open, something that clearly stuck. In 1955, Ace returned to help Batman and Robin with another case: a trained dog that committed diamond robberies. And for the next three years, Ace kept helping the duo, courtesy of John. He helped with explosives, tracking, pursuit, and just about anything else you can think of. Of course, that was Golden Age Batman. Eventually, Ace was revamped as a former Joker guard dog, rehabilitated and made into Batman's own pet. He starred in several movies, including Batman Beyond: Return of the Joker, and Batman Beyond: The Movie. 

 Finally, there's Gus, the Siberian Husky from Iron Will. This 1994 Walt Disney production was set in 1917, and showed head sled dog Gus, and all of his canine friends, bracing the cold, racing to save the family farm. They have to deal with potential sabotages from competitors, the press coverage, steep mountains, the 522-mile-long race, and the knowledge that if they fail, everything will be lost. It is only because of Gus that there is enough hope to finally win and save the farm. The film certainly left a legacy behind in real life too. There is a Husky named Slovak's Ice in Cheboygan, Michigan that is Gus's granddaughter.
