hank (my brothers part pit part am. bulldog) is gonna be a mid sized dog, and hes prolly gonna weigh close to 100 lbs. hes already strong as hell and hes only about 3 months old, already around 60-70 lbs. part rotty part lab, that must be a strong as dog. that sounds like ex g/fs rotty, it was big as one and a few years old and it played like a lab. it was funny but REALLY strong
