— -- This dog just may be the world's largest Pit Bull. Only 18-months-old, Hulk weighs a hefty 175 pounds.
Despite his intimidating size, his owners Marlon Grannan and his wife Lisa Grannan say Hulk is a sweet family dog and a best friend to their 3-year-old son Jordan.
Online videos and photos of Hulk with their son in their New Hampshire home shatter misconceptions about Pit Bulls as ruthless monsters.
Grannan's toddler can be seen riding Hulk, singing with him and napping with him.
"He's a wonderful, excellently trained dog," Grannan said. "He plays with my kid, he's great with the family and he's so, so sweet."
"Because Pit Bulls are only in the media when bad things happen, this myth of them as monsters gets perpetuated," Grannan 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."
Grannan and his wife are the owners of Dark Dynasty K9s, family-owned kennel that breeds and trains American Pit Bull Terriers as protection dogs for clients worldwide. Dark Dynasty K9s is also a member of the American Dog Breeders Association and the United Kennel Club.
"I want to emphasize that we breed and train dogs who come in stable," Grannan said. "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."
He owns 12 Pit Bulls in training and one Chihuahua. All of them live and work with him at their 150-acre home and kennel, Grannan said.
And yet, Hulk, the biggest of them all, has garnered the most attention. A video of him being weighed last month had over 7 million views as of Tuesday morning.
"My hope is that we can stop ignorance and change people's minds about Pit Bulls in a positive way with all this attention," Grannan said.
