Neapolitan Mastiffs may grow anywhere from 120 to 200 pounds, and will grow from 2 feet to 2 feet and 7 inches.

The most noticeable quality about the English Mastiff is his sheer size. It is the largest dog breed available today.

The long haired variety requires frequent brushing in order for their hair not to tangle. Caucasian Shepherds have dark and large heavy paws.
