The preparation period for pre-estrus lasts about 7-10 days. The reproductive system begins to prepare for ovulation and the body's eggs have gradually matured. The epithelium of the reproductive tract begins to proliferate, gland activity begins to increase, secretions increase, the vulva is congested, the vulva is swollen, flushed and lubricated, and mucus mixed with blood flows. Male dogs often smell it, but female dogs are not allowed to mate.

2. Estrus period:

The most direct thing is that the female dog can accept the male dog for mating, which lasts for 6-14 days. The outside begins to swell and soften, the color of the mucus flowing out becomes lighter, and the bleeding decreases or stop. The bitch takes the initiative or stops. The female dog takes the initiative to approach the male dog. When the male dog climbs up, she takes the initiative to step down on her waist, face the male dog with her buttocks, tilt her tail to one side, and open and close her vulva to allow mating.

3. Later period:

After the estrus period, the swelling of the Chihuahua female's vulva begins to subside and gradually returns to normal. Her temperament becomes quiet and male dogs are not allowed to approach. This usually lasts for two months and then enters anestrus. Expect.
