The Jenks in Connecticut are supposed to be excellent breeders. I'm sure there are other breeders in the tri-state area who are excellent, as well. I've heard good things about Susan Hertz of Let's Talk Yorkies, but I don't know personally anyone who got a puppy from her. Good luck finding your baby. Purchasing from a good breeder who breeds for health and temperament makes all the difference in the world.
