My 4.5 yo had her first heat at 15 months. First indiction I notice is bleeding. Yes, the vulva swells - it will be bigger than it normally is. Heat cycle lasts three weeks. The intact male did show interest & she would also mount him. She can also be more affectionate (dopy a bit).
Is the female mounting the male common during heat?
