A bullmastiff, as far as I know, is a bulldog/mastiff combination. They are smaller in stature than an Old English Mastiff (or American Mastiff) and I do not believe the poster that said it was 4 feet tall on the back. The dog may be obese, weigh 200 pounds.
My mastiff is 36-37 inches tall at the shoulder. Weighs 200+.
I suspect someone is exaggerating here.
I agree. I have friends that have the English Mastiff and her two males hit about 225lbs. The females being of course a lot smaller. At first, I thought they were talking about the Napolian Mastiff(may not have the name right)and they aren’t as big as the English Mastiff either. I have never seen a really big bulldog mastiff; atleast not the size of an English.
