Greyhounds Only, Inc. is a 501(c)(3)non profit adoption group serving the Chicagoland area. We are an all-volunteer based group. The dogs in our program come from various locations. We are so grateful to the racing community for entrusting us with their precious ex-racers. Racing Proud. The mission of Greyhounds Only is to place retired racing greyhounds into responsible, loving homes, to educate the public about the greyhound breed, to provide access to high-quality medical care and to collaborate with others who share our common goals.
