Grizzly was actually a large shepherd as well. He was a bit over 100 pounds. It took both of my parents to get him off the cat the first time. It only took a few times before he learned what he was supposed to do. Then all it took was for my mom to grab the scruff of his neck. Even I could do it.

We were eventually able to get him to the point that he would see a cat and almost start to chase it, but we could call him, tell him to leave it, and he was fine.

He died young though, at age 6. We have no clue why, he just layed down and died, literally.
