49. Saint Bernard
Almost everyone alive in the 90s can recall the movie “Beethoven,” which starred the massive Saint Bernard. They’re a large dog breed and have a lot of drool and long fur. However, people originally bred Saint Bernards to be working dogs to rescue people from avalanches. They have a great sense of smell and are very social dogs who care about people, making them great family dogs and great protectors. However, because the breed comes from the Swiss Alps, they are very sensitive to heat and shouldn’t be left outside in the summer heat.
