Are the Shar Pei and Rastreador Brasileiro both dog breeds?
Rastreador Brasileiro The Rastreador Brasileiro (in English, Brazilian Tracker) is a large breed of dog from Brazil, first recognised by the Fédération Cynologique Internationale in 1967, but an outbreak of disease, compounded by an overdose of insecticide, wiped out the breed's entire breeding stock. The FCI and the Brazilian Kennel Club (Confederação Brasileira de Cinofilia) then declared the breed extinct in 1973 and delisted it. Since then, efforts have been made to re-create the breed. The Rastreador Brasileiro is a hunting dog of the scenthound type. The breed is also known by the names "Urrador" (for its hunting cry) or "Urrador Americano", in reference to the American (U.S.) coonhounds in its background.
Pražský Krysařík The Pražský krysařík (Prague Ratter) is a small breed of dog from the Czech Republic that is rarely seen outside its country of origin. It is the smallest breed in the world by breed standard, because of the maximum height of the dogs, unlike Chihuahuas who are measured by weight.
