Your dog isn't an American bull mastiff. He's a mix. The bull mastiff head is broad and flat like a pit bull, but the nose is much shorter.
Re: first answer
Here is the website where I thought he would possibly be an American bullmastiff
http://www.dogbreedinfo.com/a/americanbullmastiff.htm
simply because he is not the purebred bullmastiff, they said he at healthy weight of 75 pounds at a year and a half.
The previous owners said he Australian Bullmastiff, but mainly has mastiff and boxer in him
Look at his photos I also included a short video of him
He has a gigantic head and it is square, previous owners told me there is no pit in him at all
first photo he's on the left with his sister

Maybe somone out there can tell what breed he really is "yeah, I know he a heinz 57"
He is a great looking dog! I can definitely see why you think he might have some pit bull in him. Chek out the American staffordshire terrier. Your dog looks pretty close to it. My brother has an Am. staff and their great dogs. It was one of the breeds used to create the pit bull. Keep in mind, some times people aren't totally honest about the breed because their afraid you won't take the dog. Pit bulls get a lot of bad press, but a dog is only as good or bad as it's trained to be. I always compare it to a piggy bank: You're only going to get back what you put in.
In general I would say a mastiff.
I am not absolutely sure which breed was the FIRST war dog. I have a large beautiful Poster showing the dog breeds used during World War II. They are the Doberman, Bullmastiff and German Shepherd.
An English Mastiff weights around 220 lb and a Tibetan is around 190. The greatest weight ever recorded for a dog is 343 lb and it was an English Mastiff.
a bull mastiff would win in a fight especially if you take good care of it and give it the right food it needs to grow and let it have enough space to run but if the dog was sick and weak a German Shepeard would win in a fight
To name a few there is the Affenpinscher, the Afgan Hound, the Airdale Terrier, the Akita, the Alaskan Malamute, the American Cocker Spaniel, the American Eskimo Dog, the American Foxhound, the American Staffordshire Terrier, the American Water Spaniel, the Anatolian Shepherd, the Australian Shepherd, the Australian Cattle Dog, and the Australian terrier.
It is a noun. Is that what you are asking?

Eight years is considered the average lifespan for a bullmastiff. In general, larger breeds have shorter lifespans than smaller breeds.
No, according to the American Kennel Club (AKC), the Australian Shepherd is not one of the top 5 most popular breeds in Washington DC in 2009.
They are both amazing dogs but probably an Australian shepherd
i would personally say an Australian shepherd but i also like the boxer
Its not a Australian shepherd its a border collie. Does it have black fur?
