Zeus is the new tallest dog alive according to the 2013 Guinness Record Book. This 3-year-old Great Dane from Michigan is 44 inches (2.13 meters) high when standing, only one inch taller than Giant George, the former record-breaking dog. He needs 12 cups of food a day to maintain his 155-pound (70-kilogram) body weight. Because he is the size of a regular donkey, his family had to buy a van, since they can't all fit comfortably in a regular car.

On the other end of the dog size records is Boo Boo from Kentucky, who is 4 inches (10,16 cm) tall, only ten percent of Zeus' height. She has holds the title of the smallest dog living for several years. Hopefully, there will soon be a picture of Zeus and Boo Boo.
