This dog was believed to have originated from South Africa and has been known to keep lions away from people. That said, this breed is not the one to mess up with! They are only semi-domesticated. Rhodesian Ridgebacks are not fond of strangers, so they need a lot of positive reinforcement as they can be oversensitive to certain situations.
