The work of the Sidmouth-based Donkey Sanctuary is to be shown on BBC Animals 24/7 on Thursday 28th February at 9.15 am.
The filming took place last year when the Sanctuary rescued a donkey and a mule near Heathrow.
Amanda Gordon spokeswoman for the charity says: "We are really looking forward to seeing our work in action on primetime television.
"Shrek the mule had long misshapen feet when we found him, and his friend Jacko, had a skin complaint which caused hair loss and bald patches. Thankfully they are both doing really well at one of our outlying farms.
"The production company were lovely to work with and did not intrude in any part of the rescue."
