His volunteer trainer, Sandy Steinblums, can be heard on a Facebook video of the meet and greet asking Ace to "stay" and lay "down."

The Dodo reported that Steinblums gave some background for those who didn't know Ace's story in a comment.

"This puppy is one I raised (as a volunteer) for Guide Dogs of America (in California). He is training to be a guide dog for the blind. We went to Disneyland for a few hours as a socialization experience," Steinblums said. "What you didn't see after the 14-15 seconds of video where he settled in a "down" was his "down/stay" for a few minutes while Pluto tried to break his stay."

Steinblums said Ace started his formal training with the organization in January.

As a volunteer, she gets guide dogs socialized and gives them obedience training.

The trip to Disneyland gave Steinblums the opportunity to give Ace more real world training.

"I am proud of him and love the Disney characters for being so kind and helpful," she said.

After six to nine months of work with licensed trainers, Ace, like many guide dogs in training, will have the opportunity to graduate and be matched as a guide dog to a person in need.
