i was just wondering if anyone has an educated guess on how big my boys might possibly get? I have a general idea, just wondering what some of u think? Duke will be 9 months in a couple of weeks and he is right at 70 lbs. now. And Chance will b 16 weeks friday, and he is almost 30 lbs. But chance is growing fast and his paws are already almost the size of Dukes. The pic of Duke is when he was only around 6 months or so. As u can see the christmas stuff in the background, and he was born on the fourth of july.
