I’ve always known this to be true, but I didn’t really realize how true it was until we rescued Molly and helped to rescue Scraps. The level of devotion from a dog who knows you have saved it from being put down, who knows you have given it a home when no one else would . . . and believe me, I think they do know . . . well, it is truly beyond compare.
