If you stick strictly to records, the English Mastiff named Zorba held the official record at over 343 pounds. That’s heavier than most adult male gorillas. Let that sink in for a second.
But today, it’s a toss-up. Great Danes win on vertical impressiveness, while Mastiffs win on sheer bulk. And the Irish Wolfhound wins on height-plus-elegance. So, the answer is: it depends on how you measure “biggest.”
No matter which one you pick, you’re getting a dog that makes everything else look tiny. And honestly? That’s just awesome.
