#4 Cane Corso
Originally from Italy, the Cane Corso is better known as the Italian Mastiff, and it is a type of dog breed that can easily get to 130 pounds. Well-muscled and extremely athletic, the Cane Corso is not the type of dog you can raise in a small apartment. He needs lots of space and exercise every single day. The breed is one of the smartest in the world, so you need to train him from a very early age to get him accustomed to kids and other domestic animals.
