Watch Clifford the Big Red Dog (2021) online

Clifford: The Big Red Dog, directed by Walt Becker, tells the story of a red colored puppy dog, which is given to a little girl, Emily Elizabeth (Darby Camp), for her birthday by a very eccentric old man (John Cleese). When the girl asks how big the puppy will become, the man replies that it all depends on how much affection she will give him. Emily, however, does not imagine that this is literally so and the next day, when she wakes up, she realizes that Clifford, this is the name of the puppy, has grown to the point of becoming an oversized dog.
Now Clifford is still a puppy, but he is over 3 meters tall and with his enormous size he throws the small New York apartment, where Emily lives, into complete chaos. Taking care of this gigantic problem are her mistress and her uncle Casey (Jack Whitehall), who must resolve the situation before Emily's mother comes home. For Emily and Casey begins a great adventure - in every sense - around the Big Apple with the giant red puppy.
