What Is the Biggest Dog Breed in the World?
The English Mastiff holds the title for the biggest dog breed in the world when it comes to overall size — that means height + weight combined. These gentle giants can weigh over 250 pounds and still be loving, loyal companions.
But the “biggest” can also mean tallest, and for that, the Great Dane takes the crown.
