When does a giant dog go into estrus? A giant dog usually goes into heat for the first time 8-10 months after birth; an adult giant dog goes into estrus twice a year, usually in spring and autumn, that is, from March to May and from September to September. In November, each period lasts for about 21 days; during estrus, you must pay attention to hygiene and care, and it is best to put on physiological pants for your giant dog.

The first estrus of a giant dog is about 8-10 months after birth, when the dog’s reproductive organs are basically fully developed. However, due to factors such as climate, environment, and growth conditions, some dogs come into heat earlier and some dogs come into heat later. It is normal for dogs to come into heat for the first time before one and a half years old.

Usually adult giant dogs will go into estrus twice a year, mostly once in spring from March to May and once in autumn from September to November. When a female dog is in estrus, red mucus will flow out of her vagina, which is commonly known as "menstruation." The estrus lasts for about 21 days. At this time, the dog will have symptoms such as frequent urination, decreased appetite, like to run outside, and like to be close to male dogs.

When the giant dog is in heat, the owner should pay attention to supplementing the dog's nutrition. You can add supplementary food to the dog, such as chicken breast, fish, cabbage, carrots and other foods, cook them and chop them, and add them to the dog food. If you don’t have time to make complementary food, you can also buy high-quality nutritional paste to feed your dog. 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.

And during estrus, you should choose a soft kennel for your giant dog. It is best to have two kennels that can be replaced with each other for easy cleaning. We must pay attention to the cleanliness of the kennel. After washing, it is best to expose it to the sun for sterilization and disinfection. Try not to bathe your dog during estrus, as the dog’s reproductive organs are susceptible to infection at this time.
