Ehrlichia canis is an obligate, intracellular bacterium that acts as the causative agent of Ehrlichiosis, a disease most commonly affecting canine species.
 This pathogen is present throughout the United States (but is most prominent in the South), South America, Asia, and Africa.
 First defined in 1935, "E. canis" emerged in the United States in 1963 and its presence has since been found in all 48 contiguous United States.
 Reported primarily in dogs, "E. canis" has also been documented in felines and humans where it is transferred most commonly via "Rhipicephalus sanguineus", the brown dog tick.
The crab-eating fox ("Cerdocyon thous"), also known as the forest fox, wood fox, or Maikong, is an extant species of medium-sized canid endemic to the central part of South America, and which appeared during the Pliocene epoch.
 Like South American foxes, which are in the genus "Lycalopex", it is not closely related to true foxes: "Cerdocyon" comes from the Greek words "kerdo" (meaning fox) and "cyon" (dog) referring to the dog-and fox-like characteristics of this animal.
Mucuchí (Venezuelan Sheepdog) is a dog breed from Venezuela (specifically from Sierra Nevada de Mérida).
 The dogs have a short coat with feathering along their limbs.
 The coat color is either white or white with splashes of colors such as honey or tan, or shades of black and gray.
Dukecynus is an extinct genus of meat-eating metatherian, belonging to the order Sparassodonta which lived in South America during the Middle Miocene (Laventan), between about 13.8 and 11.8 million years ago.
 The name of the genus meaning "Duke dog", for the Duke University and the Greek word "cynos", dog, for the pretended similarity of this animal with dogs.
 A single species known so far, "Dukecynus magnus".
 The species name "magnus" derives from Latin for big, to reflect their great size.
The cynodonts ("dog teeth") (clade Cynodontia) are therapsids that first appeared in the Late Permian (approximately 260 Ma).
 The group includes modern mammals (including humans) as well as their extinct ancestors and close relatives.
 Nonmammalian cynodonts spread throughout southern Gondwana and are represented by fossils from South America, Africa, India, and Antarctica.
 In the northern continents, fossils have been found in eastern North America as well as in Belgium and northwestern France.
 Cynodontia is one of the most diverse groups of therapsids.
Papilio cresphontes, the giant swallowtail or in its larval phase the orange dog or orange puppy, is a swallowtail butterfly common in parts of North America and marginally into South America.
 In the United States and Canada it is mainly found in the south and east.
 With a wingspan of about 10 - , it is the largest butterfly in Canada and the United States.
A Schipperke ( ; ] ) is a small Belgian breed of dog that originated in the early 16th century.
 There has been a long informal debate over whether this type of dog is a spitz or miniature sheepdog.
 In their home country of Belgium they are considered a small shepherd.
Cyonasua is an extinct procyonid genus from the Late Miocene to Late Pliocene of Argentina (Ituzaingo, Epecuén, Huayquerías and Cerro Azul Formations) and Venezuela (San Gregorio Formation), South America (7.3 to 3 million years ago).
 Its name in Greek means "dog-coati" because its features resemble those of a dog and a coati.
 Its ancestors likely arrived from Central America by island hopping, as perhaps the earliest southward mammalian migrants of the Great American Interchange.
 Its predators were terror birds and carnivorous metatherians.
 It possibly evolved into the bear-like "Chapalmalania".
Fox dog is a name given by some naturalists to wild dogs of South America with a fox-like appearance.
 Among them are:
The bush dog ("Speothos venaticus") is a canid found in Central and South America.
 In spite of its extensive range, it is very rare in most areas except in Suriname, Guyana, and Peru; it was first identified by Peter Wilhelm Lund from fossils in Brazilian caves and was believed to be extinct.
 The bush dog is the only living species in the genus Speothos, and genetic evidence suggests that its closest living relative is the maned wolf of central South America or the African wild dog.
 The species is listed as Near Threatened by the IUCN.
