Luke Robinson, co-founder of 2 Million Dogs shares more on the "Summer of Murphy Tour" -- a non-profit that started after his two dogs walked from Austin to Boston to after he lost another one of his dogs from cancer. From there, Robinson started the "Summer of Murphy Tour" in an effort to raise awareness about the links between human and companion animal cancers.
Luke and his dogs will be at the Liberty Fall Festival on Friday from 11 a.m. to 5 p.m. There is also a puppy up walk in November in Liberty. It will help raise money for Two Million Dogs.
