That pup is huge for 12 wks. Looks great!
How big do you think she will get?
she will probaly get to be about 24 inches high she might not even get that big . stayy x bullmastiff dogs seem to always be big when there pups but they dont grow very tall they just fill out they . the taller they get the more bulk the have so yea but i dont think she will get much bigger.
