My sister rescues them also! They are wonderful pets -- any greyhound track will have a rescue that is usually dedicated to helping each dog find the right person. If you need further help, PM me for the contact here and they can help you with a rescue near you -- they all network.
Best of luck!
Several of my co-workers have adopted dogs from the GPA - Greyhound Pets of America. They adopted from the Tennessee chapter, but there's a Maryland chapter. In each instance, the GPA helped them choose dog suited to their specific needs - high prey, low prey, only dog, etc. They really know the dogs they have for adoption and care about placing them in the right home. The link above is for the Maryland chapter.
I understand the need for a reputable rescue. You will only get high praise for the breed from me - I miss mine so much, she was perfect for me and adored me, was loyal and obedient with low prey drive....
Write to the rescue and tell them all you want or do not want in a dog - they picked the perfect match for me. It does stake a little time to get them to fit into their new lives since everything is so completely different to what they are used to.
I hope your friends can find it in their hearts to help out one of these lovely dogs.
