How often do female Chihuahuas go in heat?

Answer 1

Just the same as any other dog,
Rule of thumb, twice a year.
And for roughly a fortnight.
They are more prone to being fertile in the second week.

Answer 2

It is the same for all dogs regardless of breed. Here you go.
Sexually mature female dogs will go through a heat cycle once, or more commonly, twice a year. Each cycle consists of four stages:

1. Proestrus: Characterized by swelling of the vulva and release of a bloody vaginal discharge. Sometimes the discharge is milky and other times dark red (or somewhere in between in colour). Between bitches, there is a large variation in the length of proestrus, with an average length of 9 days, and a range of 1 to 17 days. This is the "pre-heat" during which the male is progressively more attracted to the female, but the female still rejects the male. This is a high female hormone (estrogen) stage.

2. Estrus: This phase is often termed standing heat because it is during this stage that the female will receive the male dog. Average length for estrus is 9 days, but again, between dogs there is large variation (range 3 to 21 days). At this point, the discharge may be absent, or perhaps straw coloured. This stage is characterized by an increase in progesterone hormone and an LH (luteinizing hormone) surge that leads to ovulation.

3. Diestrus: At this point, the female usually no longer stands for the male, especially further into the diestrus stage. Vaginal discharge tapers off and the diestrus phase lasts an average of about 60 days. Diestrus begins 6 days after ovulation. Progesterone hormones remain high throughout this phase.

4. Anestrus: This is the resting phase between the active portions of the cycles. It normally lasts about 5 months.

Hopefully that answers all of your questions. If not surely one of the sources that I listed below can help you out.
