Butler claims that she has no fears about her pet pooch appearing in TV or movies, claiming that Pudsey is ready for the challenge.
"I've seen The Artist, and Uggie is really cute and he is great, but I know my Pudsey could perform on camera, too. He would be great in a film," Butler told the Daily Express.
Speaking to The Sun, she added: "I could totally see him in films, he really knows how to pose for the camera and I reckon he'd make a better actor than Lassie."
Simon Cowell was a huge fan of Ashleigh & Pudsey on Saturday's Got Talent auditions show and has previously stated that he would love to discover a "new Lassie" on the ITV1 programme.
He also claimed at the show's launch this year that he would be willing to perform with a dog act if they reached the live final.
Britain's Got Talent airs on Saturdays at 8pm on ITV1.
