How Big Do Pit Bulls Get on Average?

Pit bulls typically weigh between 30 and 60 lbs (13-27 kgs), making Hulk the pit bull a true exception. His massive size, nearly four times that of the average pit bull, comes with potential health risks. Such a size can affect agility and put stress on joints, potentially shortening a dog’s lifespan.

Hulk’s colossal size is all thanks to his genetic luck as a lovable mutt. His massive appetite included devouring 4-5 pounds (about 2 kgs) of ground beef daily to satisfy his hunger!

Hulk, born on September 7, 2013, in Florida, USA, boasts a striking brown and white coat. From day one, Hulk was cherished by his breeders, Marlon and Lisa Grennan. He made his debut in a video clip on December 20, 2013, weighing 62 pounds.

Following his debut, Hulk became a regular on the DarkDynastyK9s YouTube channel, showcasing his growth journey. In February 2015, a viral video showcased Hulk’s immense size at just 17 months old, amassing over 13 million views and captivating the world.

This fame led to features on various blogs and channels and even a television appearance in April 2015. Hulk’s story became a sensation!
