We’ve rounded up 11 of the most massive mutts for you to marvel over!
1. Newfoundland
Originally bred as working dogs to help fishermen, Newfoundlands are absolute units weighing 100-150 pounds. Their flat coats and webbed feet make them excellent swimmers. These “nanny dogs” are patient, devoted, and amazing with children.
2. Leonberger
This fluffy breed gets its name from the German town of Lemberg. Leonbergers can weigh between 120-170 pounds and have a striking lion-like mane. Though large, they are known for being obedient, eager to please, and great with families.

Tosa Inus hail from Japan and were historically bred for dogfighting, though today they make loyal companions. These muscular mastiffs can reach 200 pounds and over 2 feet tall. They have a naturally protective nature.
4. St. Bernard
You’ve probably seen pictures of this iconic breed rescuing people in the snowy mountains. St. Bernards can reach up to 180 pounds and over 30 inches tall at the shoulder. Their thick fur coats keep them warm in cold climates. They make great family pets but need plenty of space to move around.
