Wow, that's a big boy! My Crook is 98lbs himself. He sired a litter of pups that are all full grown now at 80-95lbs. I thought I had big boxers.I have searched and searched and I cannot find a boxer bigger than mine. His name is Tyson and he has weighed as much as 125lbs. He is about 118 currently! He is a AKC registered pure bred boxer.
