Online classifieds, such as Craigslist, often have listings for puppies that are free to a good home. Though Craigslist prohibits the sale of animals, rehoming is permitted for free or for a small adoption fee. Most local newspapers also have sections where owners can adopt out their pets.
When searching for a free puppy in newspapers or online advertisements, ensure that the puppy comes with documentation of health records. When adopting directly from the owner rather than a reputable breeder or humane society there is less assurance the puppy has been well cared for and is in good health. Requesting proof of vaccination and veterinary records can help would-be pet owners avoid adopting a potentially unhealthy puppy.
