Great Dane saves owner from rattlesnake bite in California By: KGTV Staff and last updated 2021-05-21 11:40:10-04 OCEANSIDE, Calif. â A Great Dane named Mia is recovering at her Oceanside home after playing the role of hero during an encounter with a rattlesnake. Two weeks ago, during her lunch break, Megan Montano stopped back at her home and let out her two dogs onto her backyard patio. Montano knelt down to put the leash on her chihuahua, Rebel, when she felt Mia race to her left. âThen all of a sudden, (I) kind of felt her bump into my side and rear back while making a noise," Montano said. "I threw my head to the left and I saw the snake."
