Clifford the Big Red Dog or simply Clifford is the titular main protagonist of Norman Bridwell's children's books and the PBS animated series of the same name and its prequel Clifford's Puppy Days. He is adopted by Emily Elizabeth Howard as a very small puppy and eventually grows enormous. He is a red labrador.
As a full-grown dog, he was voiced by the late John Ritter, who also portrayed Ben Hanscomb in Stephen King's miniseries IT. As a puppy, he was voiced by Lara Jill Miller.
Clifford is a helpful, outgoing and a friendly dog and clumsy. He will always help his buddies in their times of need and give them amazing advice. However, being kind and understanding doesn't prevent him from having standards. He also can be gullible and naive and sometimes believes everything he is told. In one episode, a dog tricked him into digging someone's hole and got Clifford blamed for it. Clifford has a tag in Clifford's Really Big Movie.
Clifford is a giant red dog, which sometimes he gets into trouble because of his size or is tempted into trouble by his friends and those he meets. His size, like giants in medieval legends, is inconsistent—he is often shown as being about 25' tall from paws to head, but can appear far larger.
