Zeus, the world’s tallest dog, has sadly passed away due to bone cancer. This Great Dane achieved the prestigious Guinness World Record title in 2022, standing at an astounding height of 1.046 meters (3 feet 5.18 inches). Following a cancer diagnosis, Zeus underwent the amputation of his front right leg. Tragically, the three-year-old record holder developed pneumonia after the surgery and passed away in the early hours of Tuesday, marking a heartbreaking end to his remarkable journey.
