Hey, Amy--
I'm Sheryl, the sad, currently dogless, dog--friendly LA apartment hunting one around here. I have to hang out and cyber love everyone else's babies, because I can't have my own right now.
Why can't you have them both?? You have more than enough cute little girls to help train them--just one would get awful spoiled with all those little girls loving on him. And even as big as Newfie's are, there's just no WAY all of them can pet him together, and it will cause wailing and gnashing of teeth.
You definitely need them both. For you children's sake.
