i never really had a pref growing up. though as a kid i thought it was cool that females could have puppies. now after meeting many dogs, i am defently more sided towards males. i don't know how to explain it, but the females are just like human females...so annoying in their own way. (i am female too, so don't try to get me for being a male pig.) and you don't have to worry about males getting all weird when they go into heat.
