Glad to hear that your little girl is OK. Congrats on the puppies.
Breeding ANY SIZE female can be risky. What happened to your little one can happen to a 5-7 pound female yorkie also. Big puppies, one large puppy or a stuck puppy can cause problems (c-section). Every birth is different.
This was the first year that all my puppies in every litter survived. Up until now one out of just about every litter died.... (stuck... too small... etc)....and my girls are 5 pounds and above. I have never had to have a c-section on my girls..... but that time may come eventually....
Best of luck with you new little ones!
