Watch a Colorado vet sing to a scared pup before her surgery

There’s nothing like pre-surgery jitters.

So when a dog named Ruby started to lose her cool before a procedure recently, her veterinarian, Dr. Ross Henderson, traded a scalpel for a guitar.

In this video, the vet sings Elvis Presley’s “Can’t Help Falling in Love,” in a serenade that seems to immediately soothe the pup.

"It was a special moment," he told the "Today" show.

The 28-year-old veterinarian works at the Fox Hollow Animal Hospital in Lakewood, Colo., where he practices with his father, Anthony Henderson, and brother Ryan, both of whom are also vets.
