When is Labrador in estrus? The first estrus of a Labrador female dog is about 6-8 months after birth; the adult Labrador will be in estrus every spring from March to May and in autumn from September to September. -Estrus occurs once in November. The period of estrus lasts for 6-14 days, with an average of 9 days. During this period, the owner should do a good job in cleaning the female dog’s vagina.

Generally speaking, the first estrus of a Labrador 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 dogs may go into estrus. It is relatively early, and some dogs will come into heat a little later. It is normal for the first heat to come into heat before one and a half years old.

When Labradors 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 lasts about 6-14 days, and the length of time is also determined by the dog's own constitution. Generally, the average estrus period is 9 days.

During estrus, it is best to wear menstrual pants for Labrador bitches to maintain the dog’s vaginal hygiene. I also want to remind everyone that you need to always pay attention to the safety of your Labrador dog during its estrus, because the Labrador dog is restless at this time and likes to run out secretly. It is easy for problems such as getting lost and car accidents. If you want to take your dog out, be sure to wear a leash on your dog and do not let go of the leash at will.
