Tolly, those are very powerful dogs.
My wife's daughter has a Rottie/Shepard cross, and at Christmas time, I was
playing with him when he decided that he wanted to go somewhere else.
He gently just pushed me aside like I was nothing <img src="/ubbthreads/images/graemlins/ooo.gif" alt="" /> and went on his merry way.
I'm short, squat, have a very low center of balance, studied Jiujitsu for 5 years,
and weigh 185 lbs. No one just pushes me aside if I don't want to be pushed,
yet this dog did exactly that. <img src="/ubbthreads/images/graemlins/eek.gif" alt="" />
I was very impressed with his strength AND his gentleness.
Cheers
