Meet Cashel, an autism assistance dog who supports actor and musician Leo Long.

Leo stands confidently looking ahead outside the Crucible Theatre in Sheffield, wearing a short sleeved shirt, with autism assistance dog Cashel on a lead.

Cashel, a cavapoo, was originally trained during the pandemic, to support Leo as a student attending sixth form college.

Three years on, Cashel’s working life has transformed. With lockdown a distant memory, Leo’s acting career has taken off. He landed a starring role as a gifted young autistic drummer in the feel good Netflix hit, “I used to be Famous” as well as in an ITV4 series.

Cashel shared Leo’s trailer while visiting his last film set and was a comforting presence in the stage wings in the autumn, when Leo was performing in Much Ado About Nothing on the London stage.

In this interview, recorded just before Christmas, presenter Kate Fairweather hears about how Cashel came into Leo’s life, their developing partnership and how he supports Leo day to day.

We’ve featured an autism assistance dog previously on Dogs with Jobs, through an interview with its trainer and mother of its autistic partner. So it’s great to hear first hand from Leo about his lived experience with Cashel, and the difference an autism assistance dog makes to his life.

Cashel was trained and placed with Leo by the charity Dogs for Autism.

The second player above is an update, recorded in January 2023, a month after the first. It features a development planning conversation between Leo, his parents and the charity Dogs for Autism, who have kindly shared it as an insight into the level of care and thought that support a successful autism assistance dog relationship.
