Hi
I first & foremost want to wish you good luck with Lacie's pregnancy & whelping.
I myself would never want to breed one so small; not because it's right or wrong, but because it would just be to scary for me. I've read of some small dogs being bred and they do fine. The choice is YOURS. I do highly recommend an xray being done in the last week of pregnancy for any breeding female, but even more so for your small girl, to see how many pups to expect and to see their size so as to be prepared if a C-section is needed.
Please keep us posted on her progress...you may be having a litter of little Valentines!
