We raise and nurture our pets and they basically become part of our family. Some come into our homes young and tiny just like human babies. We watch their fast growth into adulthood. However, certain pets grow past what is considered their average adult size and take it to another level. In fact some pets grow so big, they break world records!

Check out some of the world’s biggest pets below. You’ll be surprised just how tall and/or heavy they are. You may also be surprised what kind of pets have actually gained these titles.
