I just got an email from my local greyhound rescue that Caliente, the dog track at Tijuana, is closing. If you're in southern California and thought about a retired racer this might be a great time to reach out to an adoption group. Retired track dogs make awesome pets.
If you are in the LA area, those rescues would be greysave or fast friends. Almost anywhere in the world you can go to greyhoundpets.org to see the group near you
