 FACT: When Owen is trying to teach Hubble to play fetch and is  throwing the ball for the other dogs, Nelly is always either at the  back of the pack or not even seen. Italian Greyhounds, like Nelly,  are built for speed and can run faster than most dogs. Most likely,  if you were to throw a ball for a Bernese Mountain Dog (Shep, who  was always in the front) and an Italian Greyhound, the greyhound  would be way ahead of the Bernese Mountain Dog.
