Liam Hemsworth joined Instagram back in August, and has been making women swoon ever since. Although busy with promoting The Hunger Games: Mockingjay with co-stars Jennifer Lawrence and Josh Hutcherson, perhaps the most important thing he did this week was to rescue a new pup. Liam?s ex-fiancée Miley Cyrus had a part in the adoption of his new love, a large shaggy 6-month-old puppy named Dora from L.A.-based Wylder?s Holistic Pet Center and Rescue. Yet this isn't his first rescue, the passionate advocate also has Tani, a mixed-breed pit bull.
