I have a 6 month old male Old English Mastiff. He is currently about 90 pounds. I was wondering if anybody could give me a rough idea about what kind of growth rate (weight) I can expect from him? 120 lbs by 1 year? 150 lbs by 1.5 years? etc.

Thanks.

I dont have any recent pictures of the big moose online, but most people melt when I show him as a pup (His name is "Tank" by the way):
