How BIG do yo think my pup will get?

Previously when I first purchased the pup I did not think he would get so big. I know he has some American Bully in his bloodline but his Dam was 55lbs (she's got the bully bloodline oddly enough) and his Sire was 75lbs tops (he's a purebred APBT). He usually weighs in at about 70lbs at the vets office. So i thought he might be normal weight like them even though his Sire is a tad above desired APBT weight. Now I have an 8 month old pup who is already about 60lbs and probably pushing towards 65lbs. I have not weighed him in months but it's very clear that's probably where he is at. Can anyone give a good estimate on how big he might end up?? I'm guessing 85 tops and averaging around 80lbs. Also, today is litterally his 8 month birthday.

 

Also, the crazy thing about all of this .... HE DOESN'T RESEMBLE A BULLY AT ALL!! He's tall and FIT but still so BIG. He's not overly big in the chest or too long. Just very very SOLID.

There's no way to tell.

 

i would have to agree with boogiemanblood, theres no way to tell
