It funny thats what everyone says about fostering but after doing it for 6 or 7 yrs I found out you don't get attached to every dog. I have cried over 1 dog in all those years and I still miss him but I know he has a wonderful home and is doing just great. He went to another volunteers home so I get to check up on him. I always make sure the dogs go to good homes and that helps. And the other thing is I do mostly puppies and I sure don't want a puppy full time again. :-)
All of our animals are rescues of one sort or another.
