Anyway the dog was wagging it's tail and having a great time so I went up and talked to the guy and he said his dog was pushing 300lbs and was starting to have hip problems (and at only 4 years old). Maybe his weight was a little off but I don't think that it is that uncommon for Mastiffs to get 250+.
my friend and coworker has an english mastiff. his dog was as heavy as 225lb. the dogs father was 215lbs. at 250lbs they are at a very unhealthy weight and they have serious joint and limb problems. typically at anything above 230lbs they dogs live a life of pain. i do believe that english mastiffs are the biggest breed of mastiff (probably also dogs in general).
hard to believe when he first got his dog as a puppy it was no more than 7inches long. how when he is on his hind legs he is easily 7feet tall.
