Lion and Rhodesian Ridgebacks. On July 15 2010, Kyle and I were stunned to see a mountain lion 10 feet from the corner of our house, watching our then 1-yr old and 3-yr old playing in the front yard. We went on a frantic search to find a huge dog that could run off a lion. Thanks forever to Dr. John Kane at UCSF who told us to get a Rhodesian Ridgeback. "And you must name him Sinha Raja, the Lion King," he instructed.
