Really? Never been around a full grown mastiff I take it....
Matter of fact, I do know a few mastiffs up close. And I’ve never seen one...nor any other breed of dog...that’s 48” high at the back.
And I do not believe anyone else has either.

Ok folks. I know it’s blarney day. But the article says bull mastiff, not mastiff, and it says four feet on his back.
At the link provided you can see the “world’s tallest dog” (tall standing up). He is shown standing on four legs near two people, and his back does NOT come up to their belts.
48” is about armpit level on most people. Think about it.
And if you know any dog that high, Guinness wants to hear from you.
