My sister just gave me one of these. He's 15 months, 175#, do you really think he's gonna be 300#?

Do you have an English Mastiff?

A friend of mine has mastiffs and the boy is around 315. The female looks quite a bit smaller but I haven’t asked in ages. Biggest dog I ever had was a St. Bernard, 175.

Best way to find out is ask the parents’ weights. It’s a great dog, no matter what.
