A study conducted by http://dognation.com revealed that the appearance of a dog has nothing to do with their aggressiveness.
Over 4000 dog owners were surveyed and the final conclusion was shocking. Although the appearance of a Pitbull gives the impression they are more aggressive, they actually were among the calmest breeds.
The most aggressive breed award was given to the Chihuahuas!!! Although they are smaller in size, they are the most aggressive among all the breeds, especially when they find themselves around bigger dogs.
