Manny Pacquiao: My Dad Ate My Dog

Manny Pacquiao ran away from home at the age of 12 ... when he caught his father eating his pet dog ... this according to his trainer Freddie Roach. 

Roach was talking to Yahoo! Sports about how the boxer's family struggled with poverty in the Philippines when he was a child -- and apparently, things were so tough ... Manny's father cooked the family dog for food.
