Although i am owner of a lone male, I have heard about heat in females and am very curious. What are the physical signs, what does it mean, what can be expected from the chin, and at what age does it start? How many times a year is it? When? Also, in another post someone mentioned a swaying dance. What is this? Also, the person mentioned that the chin doing this was a neutered male wooing a female in heat. I'm so confused...
