Duchess Meghan’s rescue beagle has his own book

Talk about a lucky dog. First a rescue from the pound by Meghan Markle, next a royal ride with the queen, and now his very own picture book.

Yes, the Duchess of Sussex’s pet beagle had a ruff start in life. But the pup gets the royal treatment in the cheekily told “His Royal Dogness, Guy the Beagle” written by “Guy the Beagle” with Camille March and Michael Brumm (Simon & Schuster, eeeE for all ages).

Prince Harry and Duchess Meghan’s new baby may be getting a much-heralded roll-out next spring.

But for now, Guy’s the guy, living it up in Kensington Palace and hanging with her highness, canine fan Elizabeth II. (The authors ignore Meghan’s other rescue dog, Bogart, who was left behind with friends.)

Guy’s story, amusingly illustrated by EG Keller, whose work was featured in the best-selling parody “A Day in the Life of Marlon Bundo,” begins in “the woods of Kentucky,” where he’s found, taken to an animal shelter and then adopted by a nice young lady in Canada. Soon the pair are curled up on the couch binge-watching “Suits,” until a certain royal suitor shows up with a ring.

Then it’s off to Merry Olde England to confusing encounters with royal guards wearing “black poodles” on their heads and face-offs with the queen’s snooty Corgis, Sir Vulcan the Great and Madame Candy the Equally Great. (A “hello” from regular guy Guy prompts this baffling reply from the crown-sporting Vulcan: “Pip-pip cheerio collywobbles Bob’s your uncle.”)

Can a Kentucky mutt with questionable manners win favor where it counts, with Her Majesty the Queen?

Let’s just say the ending of “His Royal Dogness” is a tail-wagger.

SIMON & SCHUSTER Guy the Beagle is running in some posh circles these days.
