10 extinct breeds of dogs (With Pictures)

4. St. John’s Water Dog

The dogs with the characteristic black-and-white tuxedo pattern of coat were a mix of English, Irish and Portuguese working dogs, and lived in the 16th century in Newfoundland where fishermen relied on them for hauling lines and retrieving seas and ptarmigans. Taxes implemented on dog ownership, combined with quarantines on imported dogs in the UK, led to their extinction in 1980s, with the last two male species documented in the 1970s. Golden Retriever and Labrador are its descendants.
