Dog enthusiasts, take note! You probably consider yourself something of a big dog connoisseur, but I guarantee the world’s largest dog will still surprise you. I’ve certainly encountered my fair share of giant dogs in my years as a dog aficionado, but the current titleholder deserves special recognition. So let’s explore the wonderful world of large breeds and find out if the Great Dane truly is the largest dog in the world.
The Biggest Dog in the World: Current Record Holder
The current world record holder for the largest dog is a Great Dane named Zeus. I’ve encountered plenty of large dogs that dont shed in my lifetime, but none compare to Zeus. This gentle giant measures an astounding 44 inches (111.8 cm) tall from paw to shoulder. That’s taller than most kitchen counters!
Zeus also tips the scales at 165 pounds (75 kg), which is roughly the equivalent of the average adult human. In terms of length, he measures 7 feet 4 inches (2.24 m) from nose to tail. That’s longer than many couches!
In terms of Great Danes, Zeus is a true marvel. Most Great Danes measure 28-32 inches and weigh 110-175 pounds. Zeus easily exceeds these measurements.
Today, Zeus resides in Bedford, Texas with his owners, the Davis family. When they first brought him home as a puppy, they had no idea he would grow so large. While his size has certainly made him famous, to the Davis family, he’s just an affectionate gentle giant who still believes he’s a lap dog.
Height: 44 inches (111.8 cm)
Weight: 165 pounds (75 kg)
Length: 7 feet 4 inches (2.24 m)
How Much Taller Than Average: 12-16 inches
How Much Heavier Than Average: Within the average range, but on the high end
How Much Longer Than Average: About 2 feet
Great Danes: The Gentle Giants
Great Danes earn the title of the “Apollo of dogs” with their regal allure. I’ve worked with many Great Danes, and I can always count on them to impress me with their docile personality. Despite their intimidating size, most people describe them as the “gentle giants.”
They generally stop growing taller at 18 months, but they continue filling out until they’re about three years old. Males typically measure 30-32 inches tall, while females are slightly shorter at 28-30 inches. Males weigh between 110-175 pounds, and females weigh between 100-140 pounds.
Their size is influenced by several factors, such as genetics, diet, and overall health. Their breed standard calls for an impressively large dog, so they inevitably rank among the largest breeds.
Great Danes boast an impressive resume throughout the centuries. For example, during World War II, a Great Dane named Juliana received two Blue Cross medals for her outstanding service during German air raids.
- Breed specific traits
- Kind and gentle
- Loyalty and affection
- Tolerant of children
- Short, smooth coat
- Various colors (fawn, brindle, blue, black, harlequin, and mantle)
Irish Wolfhounds rival Great Danes in height, and they are often right next to one another in this regard. Neapolitan Mastiffs claim the record for the largest head circumference of any dog breed. Their saggy faces are a unique sight to see.
Saint Bernards were originally bred as working dogs in the Swiss Alps and have also been in the conversation for the biggest dog. They have a lot of hair and a very stocky build, which makes them look even bigger. Some of these big fluffy dog breeds can make excellent family companions despite their size.
| Breed | Average Height | Average Weight |
|---|---|---|
| Great Dane | 28-32 inches | 110-175 pounds |
| English Mastiff | 27-30 inches | 120-230 pounds |
| Irish Wolfhound | 30-35 inches | 105-120 pounds |
| Neapolitan Mastiff | 24-31 inches | 110-150 pounds |
| Saint Bernard | 26-30 inches | 120-180 pounds |
Measuring and Verifying World’s Biggest Dog
Guinness World Records has very specific guidelines for determining the world’s largest dog. The main factor they consider is height (measured at the shoulders) and they have a specific measuring stick and a certified veterinarian that measures the dogs during the record verification process.
Accurate measurement is very important. The dog must be standing naturally and must be measured by a certified veterinarian using the specific measuring stick. The dog must also be measured on a flat surface and standing with his or her feet directly underneath their body rather than splayed.
Deciding what defines the “largest” dog can be difficult. Are they looking for the tallest? Heaviest? Longest? Currently, Guinness has established separate categories for the tallest and heaviest dogs.
There have been some controversies in the past. I can recall a specific case where the record holder was dethroned because there was a disagreement about the measuring process used. It’s a good example of why standard practices are essential in any records verification process.
- Measurement guidelines:
- Height (measured at the shoulders)
- Dog must be standing naturally
- Measured by a certified veterinarian
- Requires photographic and video evidence
- Sometimes requires witness statements)
Genetics Behind Giant Dog Breeds
The size of giant dog breeds, such as Great Danes, is primarily determined by genetics. In my years of studying canine genetics, I’ve been intrigued by the intricate web of genes that come together to create such large dogs.
Research has revealed that approximately 50% of the size differences we see in dogs can be traced back to just six genetic regions. The most important of these regions is the IGF1 (insulin-like growth factor 1) gene, which is instrumental in controlling growth and development.
Over time, selective breeding has magnified these genetic characteristics. Essentially, breeders always selected the largest dogs as the parents, and the result is that the breeds are now significantly larger than their ancestors.
Ongoing research in canine genetics is revealing even more insights. Scientists are studying how these genes interact with one another and what other variables may play a role in size. This research is not only advancing our understanding of dogs, but it also has applications to human genetics and growth disorders.
Care Requirements for the Biggest Dog in World
Caring for the largest dog breed in the world is a big responsibility. I’ve consulted with many owners of the largest dog breeds, and it’s a significant commitment. These dogs eat massive quantities of food. For example, a dog like Zeus eats about 4-8 cups of high-quality dog food each day.
They require moderate exercise. They’re not as energetic, so they don’t need high amounts of exercise. A few daily walks and some playtime is usually all they need. However, they do need plenty of indoor space to stretch their legs comfortably.
Grooming the largest dog breeds is a big task. Regular brushing is a must to manage shedding, and their size significantly increases the amount of surface area to wash during baths. Also, don’t forget about trimming their nails and caring for their teeth!
The largest dog breeds come with significant financial considerations. Just the cost of food will be a large expense, and you’ll also need to upgrade everything from veterinary care to beds and toys.
- Care requirements:
- Food consumption: 4-8 cups per day
- Growth maturity timeframe: 18-24 months
- Regular exercise: 2 walks and playtime
- Plenty of indoor space
- Regular grooming and hygiene
Health Concerns for Giant Dog Breeds
Giant breeds, like Great Danes, experience various health problems associated with their size. During my time working with these dogs, I’ve learned the importance of preventative care.
Unfortunately, giant breeds have relatively short lifespans. On average, they live about 7 to 10 years. Regular visits to the vet are important so you can identify and address health problems early.
Hip dysplasia is one of the most common health issues in larger dogs, which occurs when the hip joint doesn’t form correctly, ultimately resulting in arthritis and pain. Another major concern is bloat, also known as Gastric Dilatation-Volvulus. This is a life-threatening condition in which the stomach fills with gas and twists over on itself.
They’re also prone to joint problems because their bodies simply can’t support their size. Additionally, larger dogs are more prone to heart issues, specifically dilated cardiomyopathy.
- Health issues:
- Shorter lifespan: 7 to 10 years
- Higher risk of hip dysplasia
- More susceptible to bloat (Gastric Dilatation-Volvulus)
- Joint problems
- Heart problems
- Regular visits to the veterinarian are a must
While giant breeds like Great Danes are impressive, it’s worth noting that there are also large poodle breeds that can make excellent companions for those looking for a sizeable but potentially more manageable dog.
Let’s Close This Out
Caring for giant dog breeds is no easy task. I’ve experienced the ups and downs of raising giant breeds, and Zeus the Great Dane is proof that these dogs can grow to record sizes. Yet it’s important to recognize the specific challenges of caring for giant breeds.
From their special diets to health issues they’re prone to, caring for a giant breed is a labor of love and knowledge. After all, you’re not just adopting a larger dog. You’re bringing home a loyal friend who will undoubtedly make a lasting impact on your heart (and likely your home as well)!
