                        thank u

Is your 12 week old puppy living in the SAME kennel as your mature bull-mastiff?   Are they left alone?  What interaction with your family does he (the puppy) have, and what interaction does your mature bull-mastiff have?

Once we know these things, we might be able to offer advice rather than opinions.

I have had Bullmastiffs for approx 30 years and in my experience NO they will not get on together as the pup gets older, especially if neither are neutured.I feel that you are taking a big risk as Bullmastiffs males or females do not get on together with the same sex.If it were my pup I would take him out of the other ones kennel as soon as poss otherwise you may find yourself with an injured or dead pup one morning.
