Thanks S_B. Went back and added a little more. Very hard to explain all those things without seeing it done with your own eyes. Ca.

There are many ways to work a dog and not many so called great secrets. Only what will work for you with a lot of time and hard work included.

You do need a proper amount of anaerobic work under controlled stress. Doing nothing but Aerobic work will leave your dog short when the pushing and shoving of body weight starts. Why long distant runners are always running somewhere. LOL When something bad catches up with them, might be trouble in paradise. LOL
