Don't let this large breed's massive size fool you. This gentle giant has the most laid-back disposition.
"The most important single characteristic of the Newfoundland is sweetness of temperament. The Newfoundland is calm, patient, easygoing, gentle and amiable — a friend to all," according to Animal Planet. But if someone threatens the Newfie's family, they're in big trouble. This sweet dog will have no problem acting protectively to step in and take care of his loved ones.
Newfoundlands have a heavy, dense water-resistant coat, reports the AKC. When full grown, they can weigh a whopping 130 to 150 pounds.
