First of all, don't blame yourself, abbysmom!
You based your decision on the information available to you and you made the decision with love--you did nothing wrong and second-guessing yourself will change absolutely nothing! Your girl needs you to be strong and focussed till she's better.
I don't have any direct experience with seromas, but a few of the other members have. If you do a search of the board using 'seroma' as the keyword, you will find quite a few threads.
Here are a couple of them:
Jaida's seroma
Belle's seroma
What has the e-vet said about your girl's prognosis? Is she home or did they keep her overnight at the clinic?
Sending
for your girl's complete recovery! She's in good hands! And remember--you did
NOT let your baby down. She's very lucky to have you as her Mom!
