Greyhound

Greyhounds were originally bred as hunting dogs to chase hare, foxes, and deer. Canines in this dog breed can reach speeds of 40 to 45 miles per hour, making them the Ferraris of the dog world.

Not surprisingly, Greyhounds made a name for themselves as racing dogs. Because of this, you can likely find them retired and in the care of shelters and rescue groups. Consider adoption if this is the breed for you.
