The Sardinian dhole (Cynotherium sardous), also known as the Sardinian fox, was an endemic insular canid, that occurred on the Mediterranean islands of Sardinia (Italy) and Corsica (France). Its range was because both Sardinia and Corsica were joined for much of the Pleistocene. It became extinct when humans began to settle on the island. Its scientific name means "dog-beast of Sardinia".
