Find free Cairn terrier puppies through dog adoption websites such as Petfinder.com or from breed rescue groups that are willing to waive the adoption fee. Free purebred puppies are difficult to find, however, and adopters may have better luck looking for mixed breeds or older dogs.
Sometimes free puppies are available from private owners; check newspaper classified ads or websites such as Craigslist.com. However, this can be a risky way to acquire puppies because they often come with health or temperament problems. People who get a puppy this way are also usually responsible for vaccinating the puppy as well as getting it spayed or neutered, which is often more expensive than adopting from a rescue group.
Most rescues charge a small adoption fee, but these are sometimes waived for special promotions. In addition to searching online, interested parties can call their local shelters and ask to be alerted if a litter of Cairn terriers arrive. Adopters who find a potential dog can ask the shelter if there are any programs available to waive or reduce adoption fees. Busy shelters with overcrowding problems may be more willing to lower fees than smaller private rescues.
Prospective dog owners can also try to locate free Cairn terriers by networking through local breed clubs. However, most responsible breeders do not give away puppies for free.
