My 7 rescues: original GS a stray, 2 GS and 2 Collies from Rochester (NY) Animal Control, PWD from an elderly person who could no longer care for her, Greyhound from Greyhound Friends of NC. What I learned from my dogs: consistency from the Shepherds, scary smartness/adaptability of PWDs, to throw all previous training experience out the window when you get a Greyhound off the track, how Collies can steal your heart, and how fun dogs are.
