The lower part of the incision that was just slightly puffy before, is now really, really puffy and red. It looks like there's a lot of fluid in there, and seems on the brink of oozing. I called the vet ASAP to put her on the antibiotics she recommended if this were to happen. In the meanwhile, I'll keep smearing Vitamin E oil on it.
I did ask if they thought Maeby's sudden lameness and this sudden inflammation were related. They seemed to think they weren't, since her walking has gone back to normal. Then I asked if they thought I should bring her in to get a bacteria culture so she could be put on the appropriate antibiotics. They said she's getting the AB. they usually prescribe for internal suture reactions. If it doesn't start clearing up though, I'll be concerned!
