If dog is a man's best friend than these should be greatest friends in the whole world! Not just because these dogs have good personality, which we don't have any doubts about, but because they really are large and by that we mean XXL! :) Here is a collection of some of the biggest dogs out there picked just for you! These people should be awarded for taking care for these giants! I just know that I wouldn't want to be a burglar in their houses! :) Please enjoy and pick your favourite!
