Disney is 'great training experience' for this adorable service dog

Service dogs are hard workers, but that doesn't stop them from being adorable, too -- especially when they're helping their owners at Walt Disney World.

Katiana Mareno's dog, Riley, helps her with many tasks. She's known as a "multipurpose service dog," Marrero told "Good Morning America."

Mareno who describes herself as having an invisible disability, said Riley's tasks consist of medical alerts, faint response and crowd control. The latter, she said, helps with neuropathic pain "so no one bumps into me and causes chronic pain."

But the duo's favorite place? Walt Disney World.

And it's not just for the obvious fun the parks bring. According to Mareno, it's a "great training experience."

"We love using the environment to help with desensitizing Riley to to the different smells, people and characters."

The annual pass holder told "Good Morning America" she and Riley visit every week.

"Being at Disney makes you forget all the bad and brings out the joy of possibility and imagination. She loves her job and she loves Disney World," she said.

The Walt Disney Company is the parent company of ABC News.
