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.
Sheepadoodle A Sheepadoodle is a cross-breed/hybrid dog obtained by breeding an Old English sheepdog with a poodle. The name (which alters "poodle" to "doodle" in reference to the Labradoodle) was coined in 1992. A first generation (F1) Sheepadoodle is a doodle which is bred from an old English sheepdog and a poodle. First generation doodles tend to have added health benefits since they are the first in their line. They shed very lightly. F1b sheepadoodles are first generation backcross sheepadoodles which mean they are bred from a sheepadoodle and poodle. This helps with allergies as this generation sheds even less than F1.
