I have only had a girl Yorkie. I can honestly say she is the spunkiest dog I have ever had and I have had some spitfires. I think that terrier personality wacky terrier personality is just as strong in males and females.
So do you get to choose male for female? It's always nice when you have a few to choose from. It can be difficult to make a decision through.
If I had it to do over again I would have gotten two!
