About that dog, "Poochie": One day [his owner] took Poochie with him to the Mississippi River, just above Memphis, to train him as a pointer. Just as they arrived at the banks, they encountered a tragedy: A group of men and boys who had foolishly tried to swim in the Mississippi were being pulled under by the strong current.
