I just noticed when sammi was laying on her back playing with a toy that her vulva is swollen. She has been spayed since she was 9 months old- 3 months after her first heat. She is now 3yrs. old. I have never noticed this before, she seems perfectly fine- peeing, eating, playing, no discharge, no redness, she isn't licking, anymore then usual that is - it looks like she did just days before her first heat but not quite as enlarged, what could this be?? Should I take her to the vet. Thanks for any help- Di
