Good luck with either decision sometimes you just have to take a look at the puppies and go for the one that seems to suit your families lifestyle. I originally only wanted a boy but when I went to go see the puppies the girl puppy came right too us was laid back and just seemed to fit the criteria we wanted for a new puppy for our family. There was a couple of factors that leaned me towards a boy was due to when the girls go in heat..I have no intentions of breeding so to me I wanted to not go through this situation but like I said when we saw our puppies I ended up bringing the girl home. We love her and we're happy with our decision. I have other family members that have boy dogs and one is having trouble the other is'nt so it really does'nt have anything to do with if they are a boy or a girl on house training its more their personalities. Good luck with your decision, your gonna love your puppy no matter which one you bring home!
