Clifford the Big Red Dog is known for being a beloved best friend to a little girl named Emily. The massive dog’s antics keep everyone laughing. However, there’s another big dog with the same name that is a bit more mellow and helpful, but still a best friend – Clifford the Canine Companions service dog.
