I guess it depends on what the definition of "short" is. I have a boxer, they are generally short-nosed and are not allowed on many airlines because of it. I don't know how long my dog could keep up a chase at his maximum speed, but he is SO incredibly fast, I doubt it would matter. But once he got there, he probably wouldn't do anything except maybe cut you off. Anyway, our gate is always closed.
