Trust me weight definitely isn't everything and 200lbs is a lot of dog to be dealing with...Our boy at 2 years and 3 months weighed in at a lean 185 lbs and is still growing and maturing...our thoughts are we are very happy with what we have and he could stop growing at any time as he has outgrown the car, his crate, and is quite the challenge to walk when he gets excited so enjoy what you have no matter what size they end up being...all in all he is the most loveable, huggable, loyal dog we have ever owned and that is what is important to us as a family...
