Arlene, lol, I do want to add something. Others wondered about being so close to a pup and letting it go. But I admit that I have gotten more joy from the love of a pup I "let go" and the love they gave and got from their new home than almost any I kept. I have rarely believed I was the ONLY or even best home for any dog. My chow/coyotee and Sayblee being 2 exceptions.
I just got a "thank you, I love you" from a chow mix I placed 12 yrs ago with one of my best friends. Sally died 8 yrs later, and a woman I had never met but who was friends/neighbors with my friend (the one who is starting a new line btw) offered to take sweet Rachel as she also had adopted her litter mate from me. Donna died about a 2 yrs later with cancer, but Rachel is still doing fine. Her children have grown up with those dogs, her son distraught soon after they got Donna that he couldn't take her for show and tell. 🙂 Count me in on those who understand placing a dog can bring and be joyful. Obviously you have found a great home.
