Ok, much better information. As long as she is getting spayed anyway then I think it is ok to do the biopsy. Thanks! Also, you may want to ask Ellie May this....b/c I remember reading that she wrote she too had to biopsy done at her spay, but the Vet only took one sample and it didn't show MVD ~ however, if they took a few samples (from other areas

) it may have showed MVD, but they will never know now....So my point is, tell your Vet to take a few samples (I think...)
Keep us posted
