I think you should dock the Rottie looking pups because, sadly, people will be people after all. Yes, they will be more likely to be adopted and I have heard of two young adult rotties recently that have fallen victim to rubberband docking attempts.
Now I'm sure you will carefully screen the homes these pups will hopefully find, but there's always that chance that they could find themselves in the posession of an idiot somewhere down the line...
Have this done asap if you are going to. And get those rear dews off too, but please think about leaving the fronts...I think they are important for use as "thumbs".;)
