Up until its time of development as a pure breed in the United States, the origin of the long-coated version of the Chihuahua is identical to that of the short-coated variety. The long, soft coat is thought to have been achieved by crossbreeding the Short Coat Chihuahua with other Toy breeds. The _Papillon_ (http://www.dogs-central.com/dog-breeds/papillon.htm) , _Pomeranian_ (http://www.dogs-central.com/dog-breeds/pomeranian.htm) , _Pekingese_ (http://www.dogs-central.com/dog-breeds/pekingese.htm) and _Yorkshire Terrier_ (http://www.dogs-central.com/dog-breeds/yorkshireterrier.htm) have been suggested as possible crosses. no wonder there's confusion!
