Leo and Cashel – A powerful parnership on and off screen

When Leo Long was partnered with a tiny 12 week old Cavapoo puppy named Cashel, a remarkable story of partnership and purpose began. Since then, Leo has emerged as a powerful and authentic voice in film, theatre, and music—always with Cashel quietly supporting him behind the scenes.

From Debut to Breakthrough: I Used to Be Famous
Leo made his on-screen debut in the 2022 Netflix film I Used to Be Famous, playing Stevie, an autistic drummer whose life is transformed through an unlikely friendship. The film reached number two in the UK and trended in over 60 countries. Leo’s nuanced performance was widely praised and led to a nomination for Breakthrough Performance at the British Independent Film Awards.

A Talent Beyond the Screen
Leo’s creativity and talent extend well beyond the world of film. His accomplishments include:

• Performing in Much Ado About Nothing with Ramps on the Moon, an inclusive theatre company championing disabled talent.

• Appearing in ITV’s Professor T.

• Contributing as a musician with both the National Open Youth Orchestra and the London Youth Folk Ensemble.

Latest Role: Teardrops from a Clown
Leo’s most recent role in Teardrops from a Clown continues to build on this momentum. The award-winning short film explores themes of connection and understanding through the story of a retiring clown and a neurodivergent teenager. Leo’s performance brings honesty and heart to a film that is already being recognised internationally for its impact.

Cashel: A Constant Support
Cashel plays an essential role in Leo’s life and has been by Leo’s side both on and off camera, offering calm, focus, and a reassuring presence, supporting Leo through the demands of acting and public life.

Leo and Cashel are living proof of what’s possible when the right support is in place. Their partnership shows how an assistance dog can open the door to greater independence, confidence, and opportunity—both in everyday life and in pursuing extraordinary goals. We’re proud to call them part of the Dogs for Autism family.

In Leo’s Words
“Cashel helps me stay calm when things get busy. He’s my best friend and my partner. I’m proud of what we’ve achieved together.”
