The Elmendorf Beast was the name given to a coyote blamed for several attacks on livestock in Elmendorf, Texas.

The Chiribaya Dog (Spanish: "perro Chiribaya" ) or Peruvian shepherd dog ("perro pastor Peruano ") was a pre-Columbian breed of dog from the southwest of Peru, identified by the 42 mummies discovered by anthropologist Sonia Guillén Oneglio in the Ilo District, Moquegua Region, on the south coast of Peru.
 It has been established that it was a llama herding dog.
 The dogs were not only an important part of the social structure of the ancient Peruvians, but they received special treatment after death as well.
 The dog variety has been referred to in various Spanish-language documentaries under different terms, such as "el perro pastor Chribaya" ('the Chiribaya shepherd dog') and "pastor Peruano " ('Peruvian shepherd'), though the ancient Peruvians did not keep sheep.
 Its original name is unknown.
 (It has been referred to more ambiguously by the term "perro Peruano " or "perro del Perú " ('Peruvian dog', 'dog of Peru'), but this has also been applied to an extant but ancient hairless variety, referred to in more detail as "perro sin pelo del Perú", 'hairless dog of Peru', or the Peruvian hairless dog, a favorite in South American dog shows.)

The Mexican Hairless cat, Aztec cat or New Mexican Hairless was a purported breed of cat first documented in 1902 by Mr. E.J.Shinick who owned a pair of hairless cats.
 The cats were novelties at this time because of their lack of a coat (fur), although they grew light fur along the back and tail in winter.
 These cats also had long Whiskers and eyebrows.
 Because they had no coat, they lost more body heat than coated cats.
 This made them warm to the touch as well as heat-seeking.
 They are well documented in media reports in the early 20th Century.
