Thanks to everyone who expressed interest in helping me find this boy a home...turns out he responded to the name Buddy, and he has found a loving home with a wonderful family in the neighborhood.  Keep an eye out for him taking walks in the neighborhood with his new family.  Anyone interested in adopting or fostering a Lab, please check with Three Rivers Lab Rescue and SPARRO;  both are local retriever rescues who are doing wonderful work with these beautiful dogs.
