Zoey the pet Chihuahua
sprang into action when a rattler threatened one-year-old Booker West as
he was playing in a birdbath at his home in Colerado.
Unfortunately brave Zoey was bitten in the process and the boy's grandfather Monty Long, alerted by the dog's yelps, came to the rescue.
The dog was rushed to a vet and for a time it was thought he might not survive.
But the story had a happy ending for the brave Zoey as well as the baby when the animal pulled through and is now running around.
