Dog Rescues Boy, 9, From Colorado River

A Labrador retriever rescued a 9-year-old survivor of hurricane Katrina from a river after the boy's raft hit a log and he fell overboard, authorities said.
The 2-year-old Lab, named Zion, jumped in the river and swam to Ryan after he began screaming for help, said Chelsea Bennett, 13, the dog's owner. Ryan held on to Zion as the dog swam back to the bank.

Now that is a good puppy dog.
