Sorry but this is for all the wrong reasons to breed a dog. If you really want to help your friend have a dog there are thousands of them in shelters that need new homes and many are small and young. Why don't you jump onto
www.petfinder.com and look through all the little ones that need a home. Breeding can change the personality of your little boy and can change his social skills. As long as you breed this way more little ones will be euthanized.
