Best way of killing dogs

[Sexbad]

I don't remember being able to run faster than the dogs, though I remember playing it on hard. Maybe they run slower than me on normal.

I don't believe that sprinting for infinite periods is all that realistic either. However, the fact that most levels are rather small and in the hubs there are various things that keep the player from sprinting around infinitely anyway. Sure, you can in the game, but that rarely means you do.
