38 Dog Breeds That Require Extra Caution and Understanding

20. Dogo Argentino

The Dogo Argentino is an excellent family protector but should be handled carefully with strangers. They can weigh up to 100 pounds and stand 26–27 inches tall. These large, strong, and smart dogs come from Argentina. They tend to show their strength when excited or feeling threatened, which can lead to outbursts or territorial behavior.
