Frequently featured on lists of the largest dog breeds, Newfoundlands (also lovingly called “Newfs” or “Newfies”) are strong, big-boned, and muscular, their enormous heads resting near an adult’s hip or higher for easy petting. Standing 26–28 inches tall at the shoulders, much of their height comes from their deep chests and broad backs, supported by strong, sturdy legs. They weigh 100–150 pounds.

Few dogs are as sweet, loyal, and laid-back as a mature Newfoundland. They take a lot of things in stride—being straddled by children, a hubbub of activity in the family room, persistent cats, and other dogs trying to be friends. Most of the time, the dog is content to nap while life buzzes all around her. Friendly and affectionate, but not overly rambunctious, she often likes to be “on” her people, leaning against them or lying across their feet. Yes, that includes babies.
