Well we don't have ultra sounds here. But I am patiently waiting for the birth. She didn't show till like the very last week. So I'm hoping. If yes this will be her last If no it will still be her LAST!
As for my Yorkies I am hoping that my male was just too young. @ 10 months I've heard it was a bit young. But I have seen 7 month old male Chihuahua's mate successfully. We will see.
