Monty dedicated his new book to his late dog Nigel.
The beloved pooch died earlier this year in May, the day after the gardening enthusiast finished writing the book.
On the day it was published, he took to Instagram to pay tribute to the much-loved golden retriever, who often appeared on his television show, posting a picture of Nigel with his other dog Nellie.
“Today is publication day of ‘My Garden World’ – available online and at every good bookshop,” the post began.
“These two were with me every day I wrote, walked and worked,” he went on to say, talking about the adorable duo.
“Nigel died the day after I wrote the last word – so the book is dedicated to his memory,” Monty continued.
