Spike - rescued greyhounds can be anywhere from 1 yr to 5 yrs old - it depends on how well they do at the track, or what their potential is.
. But no matter how many races they win,(and if they have no injuries) their careers are over at 5 and they usually meet an unpleasant end when they are used up.
If you're looking for a greyhound, there are a few rescues in Ontario!
This is Hello Archer, a 5 yr old ex-racer I fostered. He was a very sweet, gentle and clean pet.
