I highly recommend a book The Good, The Bad & The Furry for a very realistic look at all the major breeds. It is a gas to read too. I’ve shared my copy with many people and they ended up buying a copy for themselves.
Here is what the author says about Mastiffs:
Weight: begins at 120 and can exceed 200
Height: 26-36 inches
Build: Massive
Coast: short hair
Brains: Average intelligence, though some can be buttheads about training. Obediance classes are mandatory.
Bladder matters: No particular house training issues.
Trademark Traits: Well Bred examples of this lumbering beast are ( thank god) even-tempered, trainable and loving towards their families ( particularly towards children). However , they retain enough of their old traits and frightening looks, to make them extremely effective guardians.
Headaches and Hassles: This isn’t a cheap dog to keep. A full grown mastiff canhammer down 40-70 poubds of dry food each month. They require extra big clippers for their massive nails, a sleeping crate the size of a minivan , and monstrously huge toys to fit their monsterously huge mouths. Mastiffs also dig, snor, and drool by the gallon. Owners often keep drool rags nearby to wipe off the slobber. These hulking canines can be problematic with cats and other small animals if not carefully trained at an early age. Also, be advised that the might mastiff, like all giant breeds, produce movements that would make Mozart proud. If you don’t poop-scoop regularly though backyard will turn into a Superfund site in short order. These dogs are also very sloppy eaters and drinkers. After a visit to the water bowl they will leave a trail of liquid through the house. They can knock over toddlers and old folks ( w/o even trying.)
Special Perks: A stern voice is all a competent owner needs to control a well trained socialized mastiff. These dogs require regular walks and fun frolics. Nothing excessive. The typical mastiff prefers stretching out across your bed or crashing on the couch, so you may have to coax it out the door.
Bugs in the system: Mastiffs can face a raft of genetic difficulties, including hip and elbow dypslasia, heart disease, immune disorders and eye problems.

If someone broke into my house, this dog would: ** stand still and stare. This alone should ward off most intruders. If not, the mastiff will release a powerful, savage-sounding bark. And if that doesn’t work, they’ll kick butt. The whole process takes about five seconds. Mastiffs act and look lethargic,but when necessary they can move like lightening.
If you like the mastiff, check out: The more streanined ( and less drool-intensive) Great Dane. Or the slight smaller bull mastiff.
Who should get this dog: An individual or family with the cash necessary to support it in style and the inclination to give it the love and attention it craves. This is an enormous dog that will take up alot of time and alot of space.
My dog is a lab-mastiff mix and she has no drool issues at all. The fur, OTOH, is an epic twice a year when she blows her coat. If I could clone this dog, I would, as we’ve had no health issues at all with her really in the near 11 years since she came to us. Her personality is sweet, loving, clingy-during-storms, she poops where we want her and she cleans up after dinner. Very trainable ( not like the German Shepard) but she understands alot of verbal and hand commands. She snores and shares our bed in the winter. Completely happy and adaptable. More people should be like my Murphy.
