1. Pre-estrus of female golden hair

The time is about 7-10 days. Generally speaking, this is the preparatory stage for estrus, when the reproductive system begins to prepare for ovulation. The eggs are close to maturity, the epithelium of the reproductive tract begins to proliferate, and the female Golden Retriever is also more irritable, with increased secretions, congested vulva, swollen vulva, flushing and moist lubrication, and mucus mixed with blood. At this time, male Golden Retrievers will often smell the scent, but female Golden Retrievers are not allowed to mate at this time.

2. Female golden hair estrus

Approximately 6-14 days is the period when the signs of estrus are most obvious and mating is accepted. The vulva continues to swell and soften, the mucus flowing out becomes lighter in color, and the bleeding decreases or stops. At this time, the female Golden Retriever will take the initiative to approach the male Golden Retriever. When the male dog climbs over, she will take the initiative to step down on her waist, face her buttocks towards the male dog, and tilt her tail to one side to allow mating. 2-3 days after estrus, the female dog begins to ovulate, which is the best time for mating.

3. Female Golden Hair Late Stage of Estrus

The temperament of the female golden retriever becomes quieter, the swelling of the vulva subsides, and gradually returns to normal, and the male dog is not allowed to approach. It usually lasts for two months and then enters the anestrus period. If you are pregnant, the period after estrus is the pregnancy period.

IV. Anestrus period

The reproductive organs become inactive. It usually lasts about 3 months, and then enters the next proestrus.

Compared with female Golden Retrievers, male Golden Retrievers have irregular estrus and are relatively simple: during the breeding season when female dogs are in concentrated estrus, the testicles enter an active state. When approaching a female dog in estrus, they smell the special smell of the female dog in estrus. Can cause excitement to complete mating.
