Hi Instere0, First, welcome to the world of molosser dogs! This will be a great adventure and learning curve for both all you. Regarding your question of size, as you know, it is a real guessing game; especially with parents who are not of the same breed, or mix as it were. From what I understand in genetics, size comes from the female side of things (members can correct me here). But for the fun of it I am going to guess about the same size as my male bandog which will have more bully blood in him, and that is 115ish. Cheers,
