Hi Rory!
that is the best reason I have ever heard for wanting a new Yorkie. I'd use that reason myself, but my skinkids are all grown up and they think my Yorkie Kids are spoiled brats (they are, but that's beside the point). I am SO glad that Howard is so much loved that the kids are fighting over him
My two males get along great---- the two females FIGHT and must be kept separated 24/7. Girls ARE so much fun to dress up -- if this is a vote, I'd vote for one of each
Good luck in your search for the perfect playmate for Howard.
