Good guy Charlie shells out for teen's therapy dog

Charlie Sheen donated $10,000 to a teenager for her therapy dog.

The 'Anger Management' actor was moved by the plight of Teagan Marti, 15, who suffered brain, spine, pelvis and internal injuries in July 2010 when she plummeted 100 feet from a Wisconsin amusement park ride and chipped in to pay for the dog who will turn on lights, pick up objects and be her constant companion.
