An obese Chihuahua who could barely move has shed more than half her body weight after ditching her indulgent diet. <br /><br />Bertha tipped the scales at 13lbs when she was handed in to Muttville Senior Dog Rescue in San Francisco after her owner passed away. <br /><br />The 11-year-old pooch was more than three times the recommended weight for a Chihuahua and could barely carry the massive weight on her tiny legs. <br /><br />She was adopted by Allison Hackett, 35, in August 2017, who knew she could help the dog slim down and lead a happier life with a calorie-controlled diet.<br /><br />The footage was captured yesterday (February 6).
