When does a Golden Retriever dog go into estrus? The first estrus of a Golden Retriever female dog is about 6-8 months after birth; an adult Golden Retriever dog goes into estrus twice a year, mostly from March to May in spring and September in autumn. -Once in November, the estrus period will last for 6-14 days. During this period, the owner must take good care of the dog to avoid getting lost.

Generally speaking, the first estrus of a golden retriever female dog is about 6-9 months after birth. However, due to the influence of various factors such as climate, environment and growth conditions, some golden retriever dogs come into estrus earlier. It is normal for some golden retriever dogs to not go into heat until 10-12 months after birth. It is normal for some golden retriever dogs to go into heat for the first time before one and a half years old.

After golden retrievers reach adulthood, they usually go into estrus twice a year, usually once in spring from March to May, and again from September to November in autumn. The estrus period of a golden retriever dog lasts about 6-14 days, and the length of time is also determined by the dog's own constitution.

I would like to remind everyone that you need to always pay attention to the safety of the golden retriever dog during the period of heat, because the golden retriever dog will sneak out to look for a mate at this time, and it is easy to get lost and have car accidents. Therefore, I hope all owners will always pay attention to wearing a leash on their golden retriever dogs when going out, and do not loosen the leash at will.
