We breed and when it has come time to rehome our adults it is heartbreaking! They live in our home and are part of the family. I have never had a problem rehoming an adult to a loving family - they are spayed and once healed we place them. Tears are always shed when they go and each time I wonder if breeding is worth it? Then I get letters/calls/emails letting me know how much they love their new dog and that they have adjusted so well. I adore when I get photos. My Paris I had to place this year and I adored the photos of her on e the lap of her new family and the Thank you card they sent.
I have to say that although I would never place mine with a rescue at least they are using a rescue to find new homes and not doing worse...I have heard many a story of people taking them to kill shelters or just putting them to sleep
