Thanks to all of you for responding and for those of you who just read and pondered.
This helps put a lot in perspective in regards to size and gender. I'm not sure when we'll actually get a YT but I'm pretty certain our next dog will be a YT. I'll probably opt for a female.
For now I'll continue monitoring these forums and will post again when I have my next question or when I finally have a YT.
In the meanwhile, if any of you are or know of a reputable breeder in Utah, please let me know.
Thanks, Steve
