The Saluki is a sighthound bred especially for grace and speed. Although the greyhound is widely viewed as being the fastest dog breed with a top speed of around 45 mph, the Saluki is said to be faster, with top speeds of 48 mph. Testing this has proved difficult as Salukis show no interest in electric hares and therefore won't race greyhounds on a track. However, as their original use was for hunting desert gazelles with top speeds of up to 50 mph, the speed claim could be true. just somthing i picked up on google
