"Before you see the show, you assume the guy's a good dog trainer," Marton said of the elder Olate. "Then you see it, and you realize Richard is not managing the dogs. He is out there with his partners."
The dogs liked the crowds that gathered for "America's Got Talent" and the show they headlined in Las Vegas, the family says.
"The crowds pumped the dogs up and added to their energy," Nicholas Olate said.
The younger Olate continues to add to his repertoire, displaying his singing chops in a pop album called "Think Big." The dogs also released one, called "The Olate Dogs' Christmas," where they bark along to the music.
