42. Cane Corso
The Cane Corso is a pretty large dog originally bred in Italy to hunt large animals and provide security to property. They’re incredibly athletic and require much exercise to tire them out by the end of the day. Lots of walks, playing frisbee, and providing them with puzzling toys are all ways to keep them engaged, or else they might resort to destructive behavior. Despite being a pure breed, you might be surprised to see how many of these dogs end up in shelters and have been confused with Pitbulls.
