SMITHTOWN - Former Arizona congresswoman Gabrielle Giffords has a service dog, and News 12 has learned it was trained on Long Island.

"Nelson" was trained at America's Vet Dogs in Smithtown.

Giffords and the dog were matched up in October to see if they could work well together as she recovers from traumatic brain injuries.

Today, the duo will become an official team and will stay together.

Giffords' husband, Mark Kelly, reached out to Vet Dogs for a dog to help her with performing tasks.
