This is really interesting! I learned a lot. I didn't realize that greyhounds had such an impeccable genetic heritage. I hope people that breed them continue to practice this good husbandry, and that the tracks work together with adoption groups to find homes after they retire.

One question I did have: the hounds seem to have a lot of scars, and seem very thin when they come from the track. Is this normal? (I've never met one with a bad temperament.)
