Various classified listing websites, such as Craigslist.org, ClassifiedAds.com, and eBayClassifieds.com, offer free puppies. Regularly searching available listings or placing a wanted ad for free rat terrior puppies might yield desired results.
Before adopting a dog, all potential pet family members should meet the animal, interact with it and assess how the dog is behaving to decide if the puppy is a good match. Sometimes puppies that aren't a good fit are put up for adoption. Free puppies come with increased risks of behavioral problems and may require additional training. Always ask as much as possible before adopting a puppy, including why the animal is offered for free if applicable.
