Dog is So Happy He Wags His Tail in His Sleep

Rafael Borges adopted Frank the dog when he was six months old and in very bad shape. Malicious or not, his past owners treated him terribly. Now Frank is doing much better with his new family and is super happy all the time. How happy is he? He’s so happy he wags his tail every night as he sleeps. This adorable video is from 2013, but has only gone viral now with over 100,000 new views!
