Make no mistake—George is giant. He is 7’3" from the tip of his nose to the end of his tail. And, at 245 pounds, he’s about 100 pounds heavier than the average Great Dane.
"If George steps on you with his paw, his front paws especially, because that’s where most of his weight is, it can hurt," says David, his owner.
David says he first realized George, his first Great Dane, was special during a visit to a state fair. "There were three lions there in a pen that you could get really close to, and I remember thinking to myself, ‘My dog is bigger than these lions,’" he says.

Back home in Arizona (Tucson), the world’s tallest dog gets royal treatment. He even sleeps in his own queen-size bed. "We originally started him in a dog crate. Then, he outgrew that, and he went to a twin-size bed," David says. "Within about a year, he outgrew that."

Every month, David says George chows down on $250 to $300 worth of dog food and treats. "He’s so tall, he can actually reach down into the sink and get a treat," David says. 

George gets stares everywhere he goes—especially at the local dog park. "When I take him to the dog park, I hear comments all the time: ‘Is this a pony? You need a saddle for that thing. Is that a horse?’" David says. "I mean, if I had a nickel for every time somebody said that, I’d be rich."
When he’s not frolicking with his canine pals, you might find George riding in style on a golf cart.
"He loves it," David says. "He hops right in, and we’re ready to go. It’s one of his most favorite things to do."
