I wanted some opionions on the size of my boy! He is not a possesion, but a friend. He is 140lbs, and in great health at 8 years old. I held off on nuetering him for the chance of breeding him. I had his father for 6 years before I bred him. Thats 16 years of bloodline history. I knew most of the dogs in his pedigree. Any comments?
