Guinness World Records 2013 World's Tallest Dog
- Denise and Kevin Doorlag weren't looking for a purse pooch or some scrappy little Dachshund. No, they wanted a big dog.So almost four years ago, they brought home a Great Dane named Zeus, then just a little ball of black fur.As Zeus grew, the Doorlags's hopes did, too, one inch at a time. Now 3 feet, 8 inches tall â€“ and 150 lbs. â€“ the aptly named canine is officially the world's tallest dog, according to the Guinness World Records 2013 edition (which launches Sept. 13).
