It’s not every day that a contestant from “America’s Got Talent” walks onstage with a dog. Pam and Casper, on the other hand, aren’t your typical singing duo! For one thing, they’ve never actually competed in anything (except Pam’s work talent show). Casper, on the other hand, is a Chihuahua.

Pam told celebrity judges Simon Cowell, Sofia Vergara, Howie Mandel, and Heidi Klum that Casper’s vocal abilities began slowly, but he’s made up for it since.

“As a puppy, he didn’t have a voice,” Pam explained. “He would squeak and squawk and make the strangest noises, and then one day a year later, I was playing guitar and singing, and all of a sudden this noise came out of him.”

We can understand why the judges were skeptical at first. Pam began singing Céline Dion’s “All By Myself” unafraid, and as soon as she reached the chorus, Casper threw back his little head and let rip!

When you see these two in action, it’s impossible not to laugh! The judges adored it, and we believe you will as well. In the video below, you can see them steal the show.
