Im not a dog trainer, but the sex doesn't seem to matter in my experience. What really seems to matter is the temperament of the dog. I suggest you ask a pug breeder if one is easier then the other or just find out about pugs temperaments.
Male pug is easier to train I think. They are loving and caring. Gets trained by the situations.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
