My suspicions are true; Gabby has not been spayed and she is in heat. Is there anything special that I should do for her (besides keep her inside)? She is having a dark brown discharge, but otherwise seems to be fine. Do I have to wait a certain time after her heat cycle before I have her spayed? Thankfully Bailey is fixed, and the shelter has given me a voucher to have her spayed for free. Sorry for the questions, but I've never been through this before!
