The running definitely the dobie. Water? Not sure. If you've watched dobies run they are amazing runners. Shepherds though don't run like a deer they are more low to ground without the bounding like deer and dobies have. Both dogs can run and jump amazing amount. You can see vids on youtube of shepherds trained to jump through a vans window to go after the dude pointing a gun at you. Got to have lot of $$$$$$$$$$$$$$$ to buy one trained that well but they are out there.
