Woman hangs onto tree with her dog until being discovered and rescued from a Yuma canal

The canal current is strong and fast, making the 18-hour fight for her and her 55-pound dog's life nearly impossible while holding onto a tree. "The will to survive is what makes this a great story," says Sgt. Juan Salcido with Wellton Police, who was first on the scene to assist her and pull her and her dog out of the canal.
