Dogo Cubano
This breed of dog was introduced in Cuba to capture runaway slaves (cimarrones). After the abolition of slavery it became too expensive to feed and the breed ceased to exist with time.
Never really considered the idea that man-created breeds of animals could ‘go extinct’ Guessing these breeds aren’t/weren’t considered ‘endangered’. Kinda wish the DNA was trapped in amber/ice so I could be the only person who has this dog. Could brag about it.
