I get what you're saying, my male dog does seem more masculine to me, in the sounds he makes, the way he acts, the way he's built. My girl dog isn't even the same breed but her voice seems girlier to me.
I prefer males because all the ones I've ever had or met were more affectionate than the females I've known except my current female. I also don't like dealing with them going into heat, I had Xena spayed at 6 months because of it.
