Who Is The Fattest Dog In The World?

The fattest dog in the world is a morbidly obese English Mastiff named Hank. Hank weighs in at a whopping 343 pounds and is believed to be the heaviest living dog in the world. His owner, Mark Grannan, has been feeding Hank an extra-large portion of food every day since he was a puppy and says that he has never been on a diet.

Hank’s massive size puts him at risk for many health problems, including heart disease, diabetes, and joint pain. He is also more likely to suffer from heat stroke due to his inability to cool down properly. Despite all of these risks, Grannan says he loves Hank just the way he is and has no plans to put him on a diet or exercise regimen.
