Though the Great Dane is typically considered the largest of all dog breeds, we're going to look at a few other breeds that give this one a run for its money, including one breed that is actually even taller.
#14 English Mastiff
The English mastiff is enormous. Growing to a height of 30 inches, these dogs can weigh as much as 250 pounds. As a Great Dane holds the record for tallest dog, an English mastiff holds the record for heaviest. The biggest weight for a dog ever recorded was an English mastiff named Aicama Zorba, who weighed in at 343 pounds.
Their size is a significant part of the breed's past purpose, which included blood sports such as baiting bears, bulls and lions. Today, however, they are simply gentle giants, letting those courageous and fearless aspects of the breed's temperament sit on the back burner while the mellow, even-tempered and loyal sides come forward. They can make excellent family dogs as they are so easy-going. So if your kids are asking for either a dog or a pony, well... it's not like size should factor into your decision
