Make a big impression with the Mastiffs 2026 Square Flap Wall Calendar. The Mastiff, also known as the Old English Mastiff, is a gentle, loyal companion. This laid-back, dignified pup bonds immediately with people and enjoys attention. One of the heaviest breeds, a male Mastiff can weigh more than 200 pounds. To keep their giant bodies healthy, they require lots of exercise. Mastiff lovers will enjoy this beautifully photographed calendar. Now 100% plastic-free and completely recyclable, this newly redesigned square wall calendar is an even better way to bring stunning photos and graphic art into your home, or as a gift for your favorite person. Plus, this 12” x 12” calendar is bound in a distinctive wrap-around cover made of a heavy-duty stock paper. This protective packaging surpasses plastic wrap while being far friendlier to the planet. All of this opens to a tall, twenty-four-inch calendar showcasing the majestic breed in all its glory.
