Re: Does gender matter?
I think it's more important to evaluate each pup individually regardless of gender, be open to either.
Your mileage may vary, but my experience is that boys are easier to train, needier, and more attached/less independent. But V's are V's, they all are highly intelligent and eager to please, so either way, you can't go wrong if the breed itself works for you.
Evaluate the pups independent of gender.
......everything else is just a dog.
