The canine's agents have signed an agreement with Orion Books - who were behind a recently-published 'autobiography' of footballer Roy Keane's labrador Triggs - to write Pudsey's life story, The Sun claims.
"Pudsey's story will be a fascinating read," an insider said. "You might laugh, but this book will sell.
"We're getting a ghost writer as obviously Pudsey can't write a book himself - let alone speak English. The plan is to get it out for Christmas and make it a must-have coffee table book."
Brewer revealed that she plans to spend half of her £500,000 winnings from the show on Pudsey.
Fellow Britain's Got Talent finalists Jonathan & Charlotte and Loveable Rogues are believed to have secured record deals off the back of the ITV1 talent search.
Simon Cowell has also been rumoured to be planning to fly Ashleigh & Pudsey to Los Angeles in order to strike up a film deal once 17-year-old Brewer has completed her school exams.
