I would imagine her being around 40 lbs on the chain. She was on swim keeps, so that's the reason why she looked so muscular. I had a dog who loved to swim and he was so muscular it's ridiculous. Sometimes we go fishing and he would stay in the water for 6 hours. He was so strong he would put his opponents down right away.
I think to be great, a dog has to have that rock solid build to it. That way it's harder for them to get hurt.
I had one who didn't like to work but he naturally had tough skin. He was white and had a good bite. By the :15-:20 mark he would be covered in blood. Then at the end of the show I'd wash him up and he had nothing but scratches on him.
Tornado winning 10 and consider to be an Ace, she had to have a solid build to her.
