When considering the "biggest dog in the world," the English Mastiff generally takes the crown due to its impressive combination of both height and substantial weight. While other breeds may surpass it in sheer height, none typically match the English Mastiff's overall mass and imposing stature.
Defining "Biggest": Height vs. Overall Mass
The term "biggest" can be interpreted in various ways, leading to different contenders:
- Tallest Dog: This refers to the breed that stands highest at the shoulder.
- Heaviest Dog: This considers the breed with the most significant body weight.
- Overall Largest Dog: This combines both height and weight to define a truly massive dog.
