First off, I hope you will learn your lesson after this mistake and have your dog spayed or neutered. There are too many puppies and dogs cluttering the shelters and so many wind up being euthanized way before they should be. Giving puppies away for free is a bad idea unless you really know the people you are giving them to.
You do not mention what breed these puppies are but if they are pit bulls they could be picked up by people wanting to turn them into fighting dogs. Also there are many medical facilities that run tests on puppies and dogs that are always looking for freebies for their horrible experiments. I would hope you would not want these puppies to wind up there either.
While putting a price on puppies is hard, it could ensure that the people who enquire would be a little more responsible as dog owners. Even a price is no guarantee. If they are purebred I would recommend looking for a rescue in your area that specializes in that breed.
Sometimes they will even take mixed breeds. They could help you find good homes for them. A shelter might be okay.
Puppies, for some reason, are usually adopted without problems but not always to good homes. A rescue would be more likely to look through the background of a potential adopter to make sure the puppy did not eventually wind up in a shelter and euthanized way before its time. Hope the puppies find good loving homes where they can be healthy and happy the rest of their lives.To find a good rescue near you could try here: loveofbreeds.com/Rescue.html.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
