Any dog owner is well acquainted with the comfort that our canine friends provide on a daily basis. Different organizations have realized the healing power that man's best friends can have, and have begun using dogs for emotional aid for senior citizens, hospital patrons, and even stressed-out students. Now, Dog Bless You, a Los Angeles-based nonprofit, is working to give therapy dogs to military veterans suffering from post-traumatic stress disorder. The charity is having an online promotion until July 4. Simply like their Facebook page--for every 5,000 likes, a veteran with PTSD receives a therapy dog.
