Can a boxer or bulldog run faster?

Labs run much faster then Boxers from scientists they say a Lab is one of the fastest runners. Boxers are aggressive, but labs are Hyper. but i'd say a Lab is a better pet to have in the family with children, Cause when i was a kid i went to MY FRIENDS and IN THERE house had a boxer and it would always jump on u and bark and if u r a kid i think it'd be scary Well it was for me..............
