What is the largest dog breed on the entire planet? Have you ever wondered what is the biggest dog in the world?
Before making a list, you have to define the biggest meaning. While some breeds are exceptionally tall, if you designate the world's largest dog breed as the heaviest, that's where your final stats will end up. Only breeds recognized by the American Kennel Club were considered in compiling this list.
We then developed a list based on the minimum acceptable weight for males of the breed. Here is the biggest dog in the world.
In the event of a tie, the greater the acceptable minimum weight, the higher the ranking of the world's largest dog.
#15 Largest Dog Breed: Dogue de Bordeaux – 99 to 110 lbs
