Clifford the big red dog is supposed to be a Labrador Retriever.
Clifford the big red dog is also considered to be a bloodhound although it's said that Clifford is actually a Labrador Retriever.
The original Clifford can be found in the children's book series written by Norman Bridwell.
In the stories, which debuted in 1963, the red dog was a giant Labrador retriever.
The CGI Clifford in the live-action movie does indeed look like a Lab — a Lab puppy dyed red.
Clifford's character was created when a Harper & Row editor advised Bridwell to write a story to go along with one of his pictures.
Bridwell recalls she picked out his sketch of a baby girl with a horse-sized bloodhound, and casually said, "There might be a story in this" because there always was one.
