They introduced the Incredible Hulk to the world, and since then, he has been receiving widespread media attention. Following Hulk’s recent fame, there’s been public debates over the safety of pit bulls. Does Hulk shatter the misconceptions about this breed? Let’s find out!

Say Hello to Hulk

Hulk is an American pit bull terrier. At only 18 months old, Hulk weighs a hefty 175 pounds which is three times larger than average for his breed. He is supposedly the world’s largest dog and also a stud dog of Marlon and Lisa Grennan, a couple residing in the US state of New Hampshire with their three-year-old son, Jordan.

Hulk the Giant

Hulk was bred by Dark Dynasty K9s, a notorious backyard breeding operation. The pride and joy of Dark Dynasty, Hulk is a crossbred between the American pit bull and the English pit bull, both of which are large breeds.

While pit bulls are known for their big bones, Hulk is four times the weight of his regular counterparts. His sheer size is attributed to the combination of his genes and his protein-rich diet.

How Are Crossbreeds Made?

Like Hulk, crossbred dogs are also referred to as mixed breeds. What distinguishes them from other types of dogs is that they are usually born from parents of two different breeds. In other cases, they might be born from many generations of dogs that have diverse heritage.

Typically, the magic of crossbreeding results in a unique mix of traits and characters that the puppy gets from its parents. However, it is always vital to consider how a combination of traits can affect the puppy.

How Intimidating Does Hulk Look?

Hulk was born September 7,  2013, in Florida. The average size of a regular pit bull is 30-60 pounds. But this pooch gives the standard pit bull a run for its money.

Hulk’s gigantic head measures about 27 inches, about the size of a small horse. When he stands on his hind legs, his height can be compared to that of a tall human being.

A Cause for Concern

The American Pit Bull Terrier’s size makes most people worry, particularly because its 30-60 pound average isn’t healthy for any breed. According to veterinarians, their huge size can shorten their lifespan, interfere with their agility, and stress their joints.

Surprisingly, these risk factors have not prevented Hulk from fathering his first litter of puppies. In fact, thanks to their daddy’s big-boned nature, the puppies are expected to grow as big as he.

Where Did Pit Bulls Come From?

Originally, pit bulls originated in the United Kingdom by breeding terriers and bulldogs. They were supposed to be strong enough to participate in extreme animal sports. However, by the early 20th century, people had found other uses for pit bulls aside from fighting.

Thankfully, the practice of these extreme sports has been outlawed even though some practice it in secret. Pit bulls are now used as hunters, drivers of livestock, guardians, and pet companions. Hulk is a protector and a great family companion.

The Pit Bull Myth, Debunked

Because of the intimidating size and fearlessness of pit bulls, they’ve garnered the reputation of being dangerous. Hulk’s awe-inspiring size seems to reinforce this idea of danger.

However, Marlon disagrees with this statement. He believes that, “Because pit bulls are only in the media when bad things happen, this myth of them as monsters get perpetuated,” and added, “But it’s not true. They might not be for everyone, but under a good leader and with proper training, they make amazing family and work or protection dogs.”

More Misconceptions About Pit Bulls

More often than not, people always think that most dog-related incidents involve pit bulls. This is, in fact, wrong.

Although there are incidents regarding pit bulls, dog bite statistics from the Humane Society show that most dog bites happen with dogs that are not neutered or spayed. In addition, more statistics show that 25 percent of fatal dog bites were inflicted by dogs that are chained and are of varying breeds.

Pit Bulls Keep Danger Out

Hulk has been trained to be a protection dog. Protection dogs are breeds of dogs like German shepherds, rottweilers, and bullmastiffs, trained to guard and defend humans, homes, and livestock.

“I want to emphasize that we breed and train dogs who come in stable,” Marlon says. “Our goal is to make these dogs fearless for the intimidation factor that protection dogs need to have, not for them to be uncontrolled and maul or bite anyone. That is improper training.”

For his litter, the cost depends on if the buyer wants the puppy straight out or if they want it trained—one of his puppies cost about $30,000 straight up, but the selling price increases to around $55,000 per pup if they are to be trained as guard dogs.

These practices are likened to how underground dog fighting rings are operated. The animals make good examples of the target of underground rings. This makes the story of Hulk tragic, in addition to the considerable damage he may have.
