Just in case anyone was wondering about the size of these dog's...in my profile picture is my Boz (RIP) Oz. In that picture, he was 10 months old and weighed 160 lbs. I'm guessing had my buddy not opened the gate to the yard and got hit by a car, he would have been close to 200 lbs. by the time he had finished. I can say from experience, that the negative things being spouted by some very bad people out there are not true. You need to check for yourselves. It's to easy and lazy to simply believe something that is posted on the internet. These dogs are incredible.
