Hi Brian and Joan! Welcome to YT!
I just adore those pics, what a cutie pie! Can't wait to see your 'son' when he arrives.
Personally, older=better! May be coming to you for advice! (although I'm catching up fast!)
I have 4, 3 Yorkies and 1 Biewer. My oldest Yorkie is 14.5 years old. The 3 girls are between 3-4 years old. But, they all still act like puppies!
Glad to have you both here! Enjoy!
