I just weighed Mauser, and at 5 months, 1 week, he weighs 75.5 pounds. He'll top 80 before 6 months.
We also finished our puppy training class tonight. The instructor wants him to skip the beginner class and go straight to advanced beginner to earn his CGC (canine good citizen) certificate. He was by far the biggest and best in his puppy class (3-6 month old dogs). The whole time he was either setting or laying next to me while all the other dogs were yapping and trying to break their owners arms off tugging on the leashes. This is one dog that I'm really proud and glad I got him. He's unlike any other dog I've run across. Most are hyper and stupid, hyper and smart or laid back and stupid. He's so laid back but at the same time will come to attention and is smart as hell.
