How many pounds can an English mastiff weigh?

Answer 1

I have a female who is 15 weeks old and weighs 51 pounds.I can not tell you a full grown weight by my dog but I have known a few people with females and looked into it a bit before I purchased Princess-my female.I can tell you that an average is hard to say with English mastiffs because they seem to vary alot/some as small as the 130 pound range but many females over 200 pounds.I think that if you took 100 dogs that most of the females would weigh between 170to180 pounds full grown-3 to four years of age,but as I said there doesent seem to be an exact science to them.I would look at the parents to see what they will grow to.The parents of Princess were mom-185 pounds/dad-210 last time he was weighed but the breaders seem to think he is probobly heavier now but dont have a big enough scale to stand him on.If you are getting a mastiff you might think about how you will even know what she weighs at full size unless you go to the vet. all the time.Maybe go to the highway truck stop weigh-in?
