She had her first heat in august. It finished on the 29th of august. Spoke to vet and she advised 8 weeks until speying so she is due to go the week beginning 25th of October. Just this evening she was lying on the sofa beside me and I could smell that same smell she had when she was in heat. Then shortly after she started licking at her vulva. I’ve had a look and it doesn’t seem swollen and no bleeding. Could she be in heat again 7 weeks after finishing the last one?
