It is widely believed to be the greyhound, however, I own a lurcher, border collie/greyhound crossbreed, that can run faster than a greyhound, but does not possess its stamina, hence greyhounds are used in racing.
grey hounds and whippets
probably the dog.
The Whippet is the fastest dog. It can can run about 40 miles per hour.
The fastest breed of dog is probably the greyhound but poodles love to run and are very fast.
