Hercules

Hercules is a Neapolitan Mastiff and is said to be the largest dog in the world!

In April 2007, a photo was e-mailed and soon became a viral photo on the internet! It depicted a woman on the left, walking a horse, and a man on the right, walking the dog called Hercules, a supposed English Mastiff (despite the fact it is clearly a Neapolitan Mastiff) that is almost the size of the horse! He is said to be the world's largest dog according to the Guinness World Records. Hercules has a 38 inch neck, paws the size of softballs, and weighs 282 lbs!

There are many skeptics about this photo, and they say it was mere photo-shop. But the image is very clear, and appears to be real. Still, many people regard Hercules as a hoax.
