High Quality Content by WIKIPEDIA articles! Dognapping is the crime of taking a dog from its owner with the intention of demanding a ransom. Historically in the United States, dogs had been stolen and sold on for medical research, but the introduction of the Animal Welfare Act of 1966 reduced these occurrences. The profit available to dognappers varies based upon the value of the dog or the amount that its original owners are willing to pay as ransom. Dog organizations recommend the microchipping of dogs in order to facilitate an animal`s return to its rightful owners. The word is derived from the term kidnapping.
