Which is better: Wheaten Terrier or Yorkie?

I may be getting a Wheaten Terrier ; or a Yorkie. I have no idea! I hear Yorkies pee EVERYWHERE since they have really small bladders. But then I hear that Wheaten Terriers are aggressive and hard to train. I'm really hoping Wheaten Terriers are not bad dogs, because they are the perfect size for my family ;... show more I may be getting a Wheaten Terrier ; or a Yorkie. I have no idea! I hear Yorkies pee EVERYWHERE since they have really small bladders. But then I hear that Wheaten Terriers are aggressive and hard to train. I'm really hoping Wheaten Terriers are not bad dogs, because they are the perfect size for my family ; and if I'm correct, a reasonable energy level, which isn't TOO bad.

Please tell me any concerns and what I need to know about these dogs!
