Andy Murray and Kim Sears have one very talented pet. The couple's Border Terrier Maggie is set to "write" her own book, with a little "help" from her owner Kim.
The book, entitled How to Look After Your Human: A Dog's Guide, explores how pets can bond with their human friends.
It will be published next June by Frances Lincoln and will feature artwork by Helen Hancocks, the illustrator behind children's book Penguin in Peril. All proceeds for the £14.99 book will be donated to an animal welfare charity.

Kim, who is pregnant with her and Andy's first baby, has another Border Terrier Rusty, but Maggie is the more famous of the two and even has her own Twitter account. The canine, whose full name is Maggie Mayhem, has more than 28,000 followers online.
"Maggie Mayhem has been dispensing valuable life advice to her thousands of adoring fans on Twitter and we simply couldn't resist her wit and charm," said publisher Rachel Williams.
"Maggie Mayhem has trained some of the world's most stubborn humans (namely her housemate Kim Sears) and so there is no better canine to explain the complexities of human behaviour and guide us through the ownership journey."

Kim has travelled the world to cheer on her husband Andy, who she married in April of this year. The 27-year-old artist and the Wimbledon champion have been dating since they were teenagers and tied the knot after nine years together.
On her official website, Kim has admitted that she would like to write a novel one day, but that blogging is as far as she's got. The pregnant star, who holds a degree in English Literature from the University of Sussex, instead focuses her energy on painting, in particular animal portraits.

"I can't remember a time when I didn't turn to either paints or pencils as a means of release," wrote Kim. "I love animals, and have come to relish portraying family pets as, well…family.
"My canine partners in crime are Border Terriers Maggie (Mayhem) and Rusty (Rascal). Mags has a tendency to pick fights and chase deer (she started, Fenton copied), whilst Rusty likes to finish my tea and eat soft furnishings."
The mum-to-be added: "I adore the countryside, and think we're so lucky in Britain to have so much beautiful outdoor space in such close proximity to our big cities. Dog ownership is great for getting you out and about, even on a rainy day."
