thanks for the advice.....I guess were just gonna stick to car rides instead of walks for a while....The treadmill will definitely come in handy now, this way she can still get some sort of exercise....we dont have a fenced in yard, so I guess this means no more boxer burns around the yard for a while.....we live on a pretty secluded country road with less then 10 houses on it, but the nearest neighbour is less than 1/4mile away. They do have a GSD but I have no idea if it has been fixed.
