12 Most Loyal Dog Breeds

St. Bernard

St. Bernard

This is a massive breed that was used to rescue people in the snow in the Swiss Alps. Sometimes hikers were lost or caught in an avalanche and this breed would risk their life to save a human. They are intelligent and will bark at a stranger but not attack. They weigh 120 to 180 pounds and excel in obedience trials. They are messy though with long hair and lots of drool. They need daily exercise but can live in a smaller house. It’s nice if they have a yard though as they are so big.
