Chico, I think you have made the right decision for all of you. It is so hard to let go, but knowing the dog will have a nice home with people who do not have children should give you peace of mind. I don't know if this is the right thing to do, but what about if you think of getting another dog bringing the one you have with you to see how they get along for starters. We have a Schnauzer who is somewhat aggressive towards children and since we don't have small kids it is no problem for us and we are careful with him.
