good way to guess weight at maturity is to double the weight they are at 4 months , although this will only be an estimate its the best idea. with the weight you say right now I would guess around the 70lbs mark which looks like its about the size of the parents. they usually grow upwards for the 1st year and fill out for another 1 -2 years after. a dog isnt fully matured until age 2 -3 depending on the dog.
