St. Bernard
Source: Wikipedia
If we learned anything from Beethoven (and the following movies Beethoven 2 to 5), is that St. Bernards are loving, loyal, family dogs that really really care about their owners. These big fellows are among the best guardian dogs as well, due to their sturdy composition. This is literally the breed that rescues you in the snow from an avalanche and carries whiskey around its neck. YES PLEASE.
