Extraordinary Giant Dog Breeds Worth Investigating
1. Neapolitan Mastiff
Does this dog look scary at first glance? With endless skin folds, heavy jowls, and a massive frame, it’s easy to feel intimidated. But behind that powerful appearance lives one of the most misunderstood gentle giants.
The Neapolitan Mastiff is a rare breed originally bred in Italy, with mastiff-type ancestors dating back thousands of years.
Its loose skin was deliberately developed to protect it during attacks, making it a fearless estate and family protector.
Over time, this breed traveled across Europe with guards and warriors, influencing other mastiff lines. Today, its ancient history still shows in both appearance and personality.
As a giant dog breed, the Neapolitan Mastiff was originally bred to guard homes and assist with heavy farm work. Its protective instincts are deeply rooted, yet it remains calm and even-tempered with family.
This strong-willed dog suits experienced owners who understand training and leadership. With steady walks and gentle exercise, it becomes a loyal, affectionate companion.
2. Scottish Deerhound
Why is such a beautiful and gentle dog still so rare? The Scottish Deerhound is one of those breeds that quietly steals hearts once you truly understand it.
Sweet, calm, and well-mannered, this dog is often overlooked because of its giant size or confusion with similar-looking breeds.
Known as the “Royal Dog of Scotland,” this is an ancient breed with a history older than the Scots themselves.
Once reserved only for nobility, Deerhounds were prized for hunting large red deer and admired for both grace and strength.
Today, they are far more likely to be found relaxing in family homes. Despite their regal past, they are affectionate, sensitive, and deeply devoted to their people.
