my pup is now 11 weeks old, (gsp) i have started taking her 2 puppy socilaisation and she is very much the dominant dog, even though she is the youngest by 6 weeks. she knows how 2 read the submissive signs but i am worried she is going 2 get into trouble if she meets another dominant dog and both wont back down
am i just being paranoid or could this happen?

What other breeds is she socialising with?  If the rest of the class are made up of shelties, papillons, pugs etc then her behaviour, attitude and reactions are going to be vastly different than if she were mixing with other GSPs, labs, and other boisterous breeds.

Not sure what you mean by "dominant" however and so cannot really give you a satisfactory answer I am afraid.
