Between St. John's water dog and the Polish Hunting Dog which was known to be a landrace bred for a specific purpose?
St. John's water dog The St. John's water dog, also known as the St. John’s dog or the lesser Newfoundland, was a landrace (a dog bred for a purpose, not pedigree or appearance) of domestic dog from Newfoundland. Little is known of the types that went into its genetic makeup, although it was probably a random-bred mix of old English, Irish and Portuguese working dogs. The number of St. John's water dogs started declining by the start of the 20th century. By the early 1980s, the variety was extinct.
Terceira Mastiff The Terceira Mastiff (Portuguese: ] ) is a landrace Portuguese dog breed, also known as the Rabo Torto ("rabo"=tail, "torto"=curled/twisted). Neither the Fédération Cynologique Internationale nor the local Clube Português de Canicultura has officially recognized it. It is a remarkable ancestor to both the Cão Fila de São Miguel and the Fila Brasileiro . This breed is fully different from the Barbado da Terceira
