When does a Chihuahua go into estrus? The first estrus of a female Chihuahua is about 6-8 months after birth. Some dogs also develop late. Usually it is normal to complete the first estrus before one and a half years old; Chihuahuas go into estrus twice a year, mostly from March to May in spring and September to November in autumn.

The first estrus of a female Chihuahua is approximately 6-9 months after birth, when the dog’s reproductive organs are basically mature. However, due to the influence of factors such as climate, environment and growth conditions, some dogs go into estrus relatively early, and it is normal for some dogs to go into estrus only 10-12 months after birth. The first time into estrus before 1 and a half years old is normal. Phenomenon.

When Chihuahuas become adults, they will go into estrus twice a year, usually once in spring from March to May, and again in autumn from September to November. Estrus lasts approximately 6-14 days.

During the period when the Chihuahua is in estrus, you should pay attention to supplementing the dog with sufficient nutrition. You can choose to add complementary food to the dog, or you can feed the dog some nutritional paste, calcium powder, vitamins, etc. During estrus, if you do not plan to breed your dog, it is best to wear menstrual pants for it to prevent pregnancy and bacterial invasion.

I would also like to remind everyone that you need to always pay attention to the safety of the dog during the Chihuahua period of heat, because at this time the Chihuahua will secretly run out to look for a mate, and problems such as getting lost and car accidents may easily occur. Therefore, I hope that all owners will always pay attention to wearing a leash on their dogs when going out, and do not loosen the leash at will.
