You didn`t say whether you meant heaviest or tallest. Some of the heaviest breeds include Saint Bernards, Mastiffs, Neopolitan Mastiffs, Alaskan Malamutes, Samoyeds, Newfoundlands, and Kuvasz. Some of the taller breeds include Great Danes, Scottish Deerhounds, Irish Wolfhounds, and the Greyhounds. It is best to investigate any breed before deciding to get one to make sure if you will like it.
