There are several dogs known as the worlds largest dog. According to the Guinness Book of World Records, one of the largest dogs is Hercules, a massive English Mastiff. He was entered in the Guinness Book of World Records in 2001.  The dog weighed 280 pounds with paws the size of softballs and a 38 inch neck.  He’s owned by J. Flynn of Peabody,  Massachusetts. His owner says that he is extremely gentle and wouldn’t hurt anyone.

A born guard dog, English Mastiff’s rarely bark.  They love to please and need a lot of human leadership.  They need to be socialized well when they’re young so they don’t become aloof with strangers. The Mastiff tends to drool, wheeze and snore loudly.  They can also be somewhat difficult to train. The objective in training this dog is to try to achieve a pack leader status.

Mastiffs tend to be lazy that’s why it’s important that they get regular exercise.  Make sure that you get a very strong dog leash as these dogs are extremely heavy. Life expectancy is between 10 and 12 years.
