I would say only time will tell. I don't think there is an answer that fits your question. It was not a good thing but it is not the end of the world, or in time you may see shyness/being timid and then attribute it to this one event. The biggest reason I do not think there is an answer to your question because you are the only one who witnessed it, you saw the extent, you know your dogs and you will be raising the puppies. If she lives in a perfect world from here and does not work out, this may be the cause, but it is no way to pinpoint it the same.
Best of luck with your pups. I have seen it with mine, separated them and can't definitively say it had a negative ending because of that gang-up beat down. Hope this helps. EWO
ok thanks
