Is it possible that she has an infection? When they spay a bitch they remove her ovaries which would prompt her to go into heat when the egg drops (just like us, only we don't go into heat...well, not really anyway, lol)
If she is swollen I think there is a possibility that maybe some urine dried up around her area and she got an infection. I would consider giving the vet a call and see what they recommend. |
