I was wondering how old females are when they go into heat and what to be ready for? My Lola the last week has been backing up her butt anytime I go near her back side and will push it right up against whatever is touching her. She also is licking there a lot and she never has done that and now its all the time. She is only 5 months so Im not sure what to think because she is a little young to be in heat. I am getting her fixed in January but her Vet wants to wait tell she is around 8 months. I want to catch it before she goes into heat! thanks!
