They're not as fast as a greyhound.
A proper greyhound has decent feet, drive, wind, speed, speed and speed. They are no more reckless than any other running dog and aren't made of glass.
People shouldn't base their judgement on ex racers that they've seen run.
From what I've read so can't base it on me witnessing it,they've run them against pure greys and fairly beat them?As I said I've never seen one in the flesh but only what I've read.
