Which breed of dog is believed to be the fastest?

Answer 1

Irish Wolfhound. They are born about 1 lb and are around 100 lbs at 1 year of age. There is a MASSIVE growth spurt at around 6 months, and a good 60-70 lbs are added over the next 6 months. They are also the tallest dog breed and one of the largest.

Answer 2

The fastest dog is the Greyhound, they have been clocked at bursts of speed up to 45 miles per hour. At nearly 43 mph, the Saluki is a close second. Whippets come in as the third fastest dog. They've been clocked at 36 mph.
The fastest dog breed would ofcourse be Greyhound. They race in dog races
The Greyhound happens to be the fastest dog breed. Today, people often enter greyhounds in races to compete. They have long legs so that they can run faster. They are really fast runners, and I bet no human can beat them in a race.

Answer 3

the German Shepard an a skinny American staffordshire terrior are sorta in a tie so if anyone wants to test that then they can delete my answer.

Answer 4

Jack Russel Terrier
