From the wiki page about the condition - "Because the food stays lodged in the throat, it can often be inhaled into the lungs causing aspiration pneumonia. One way to avoid this is to make sure that every time the dog eats or drinks anything, that the dog sits for at least 10 minutes afterwards or is held in a sitting up or begging position. This requires that all food and liquid intake be closely monitored and specifically administered to the dog in regular intervals (sometimes as often as 2-3 hours) in smaller quantities." It goes on to stress the difficulties of getting enough calories, etc.

That's a hell of a lot of work, especially with a big rottweiler. As much as it would have made better sense to put painlessly to sleep at 7 weeks, I really hope there's a bleeding heart big enough out there to want to take on this insane task.
