Mercure Walton Hall Hotel and Spa, Warwickshire
For an extra £15 a night, your dog (or other pet, they’ve had an iguana here, apparently) can stay with you at this four-star spa resort. The enormous picturesque grounds, which ooze quintessential British countryside, offer great walkies for humans and mutts alike. A pet bed will be provided in the room, so let them know the size of your dog in advance. Plus, until the end of October your pooch can enjoy the ‘Happy Tails’ package, including doggy popcorn on arrival and a canine menu specially designed by a pet nutritionist, featuring salmon sashimi and beef tartare.
