Imagine a dog the size of a small donkey sitting on your sofa. Honestly, it’s hard to wrap your head around that kind of mass until you look at the stats for Zorba old english mastiff.
Most people think of Great Danes when they imagine "giant" dogs. They’re tall, sure. Leggy. But when we talk about pure, unadulterated bulk? The English Mastiff is the undisputed heavyweight champion, and Zorba was the king of them all.
He wasn't just a big dog. He was a biological outlier.
The Absolute Unit: Breaking Down Zorba’s Measurements
Let’s get the numbers out of the way because they’re kinda ridiculous. Formally known as Aicama Zorba of La-Susa, this guy was born in September 1981. He lived in London with his owner, Chris Eraclides.
By the time 1987 rolled around, Zorba was already a celebrity. He clocked in at 314 pounds. Most male Mastiffs top out at maybe 230 pounds on a very heavy day. Zorba was already nearly 100 pounds over the "large" end of the spectrum.
But he wasn't done growing.
In November 1989, Guinness World Records did another official weigh-in. The scale hit 343 pounds (that’s 155.6 kg). To put that in perspective:

- He weighed as much as two average adult men.
- He stood 37 inches at the shoulder.
- From nose to tail, he measured 8 feet 3 inches.
Basically, if he stood on his hind legs, he could have looked a professional basketball player in the eye and still had height to spare.
Life With a 343-Pound Roommate
What was it actually like to own a dog that size? Chris Eraclides often talked about Zorba’s temperament. Despite the "beast" status, he was a gentle soul. Typical Mastiff. They’re known as "gentle giants" for a reason. They don't bark much. They don't bite. They mostly just... exist in your space.
You’ve gotta wonder about the logistics. Think about the kibble. A standard Mastiff eats about 6 to 10 cups of food a day. Zorba likely put away significantly more.
Then there’s the drool. Mastiffs have those massive, pendulous jowls. When a 340-pound dog shakes its head, you aren't just cleaning a spot on the floor; you're repainting the walls.
Why Guinness Stopped Tracking the Record
You won't find a "New Heaviest Dog" in the recent Guinness books. Why? Because people are competitive and, frankly, sometimes a bit reckless.
After Zorba, Guinness World Records got worried. They realized that by having a "Heaviest Pet" category, they were inadvertently encouraging owners to overfeed their animals just to get into a book. It became a health hazard. They didn't want people turning their dogs into morbidly obese spectacles.

So, while there might be a heavier dog out there somewhere today, Zorba remains the "official" all-time record holder because the category is effectively closed.
The Genetics of a Giant
Zorba came from a strong lineage. His sire was Stablemate's Bruno of Kisumu and his dam was Gildasan Valentine Daisy of Aicama. These weren't just random backyard dogs; they were high-quality English Mastiffs.
Interestingly, Zorba wasn't just fat. A lot of people see the 343-pound stat and assume he was a walking beanbag. While he did put on extra weight later in life—reportedly ballooning to 338 pounds at one point while staying with a relative—his frame was naturally massive.
His bone structure was immense. His chest girth was 57 inches. That’s a bigger chest than most bodybuilders.
Health Challenges of the Breed
Living to age 11 is actually quite an achievement for a dog of this size. Giant breeds usually have a tragically short window.
- Joint Issues: Carrying 300+ pounds puts extreme stress on the hips and elbows.
- Heart Strain: The heart has to work double-time to pump blood through that much mass.
- Bloat (GDV): This is the silent killer for Mastiffs. Their deep chests allow the stomach to twist, which is a life-threatening emergency.
Impact on the Mastiff Community
Zorba changed how people viewed the breed. He became the face of the English Mastiff in the 80s, appearing on shows like Late Night with David Letterman.

He proved that these dogs could be massive without being aggressive. Even today, breeders look back at his measurements as the "gold standard" of what the breed’s genetics are capable of, even if we don't necessarily want every dog to be that heavy for health reasons.
If you’re thinking about getting an English Mastiff because of Zorba, you’ve gotta be realistic.
Most won't reach 300 pounds. And honestly? You probably don't want them to. A 180-pound dog is already a massive commitment in terms of vet bills, food, and space. You need a big car. You need a big house. You need a very, very big bed.
Caring for a Modern Giant
If you want your Mastiff to live a long life like Zorba, the strategy has changed since the 80s.
- Keep them lean. Every extra pound is a month off their life.
- Slow growth. Don't rush puppy growth with high-protein "performance" foods. You want those bones to harden slowly.
- Gastropexy. Many owners now opt for "stomach tacking" surgery during a spay or neuter to prevent the fatal twisting of the stomach.
Zorba was a once-in-a-century dog. He was a freak of nature in the best way possible—a massive, slobbering, loving testament to what the Old English Mastiff breed can be.
To keep your own giant breed healthy, start by chatting with a vet who specializes in "giant" or "molosser" breeds. They have different nutritional needs than a Golden Retriever or a Lab. Focus on high-quality large-breed formulas that include glucosamine for joint support right from the start.
