Does anyone have a Greyhound they are using as a blood donor? My vet just gave Samlur, my Greyt 2 1/2 Greyhound, the go ahead to be a blood donor. I am so excited that Samlur may help save a life. He is young and in Greyt health. He just had a complete exam and came out with flying colors. He is such a good boy. I am a Certified Dog Trainer, by profession and am CGC Certified tester and a member of the ADPT, but I am the most proud of this!
