Dogs begin to mature sexually when they are about 6-12 months old, which is the dog’s first estrus. Generally, the estrus lasts for about 6-14 days. If you don’t want your dog to get pregnant unexpectedly, you need to reduce contact with male dogs during this period. During this period, the female dog's estrus performance will be more obvious, such as becoming extremely excited, moving frequently, and the vagina will be swollen. After a female dog is in estrus, if she does not get mating for a long time, she will go into estrus again every 6 months. If you do not want to breed during this period, it is best to have her neutered as soon as possible.

Precautions for dogs in estrus:

1. During the estrus period, the reproductive parts of dogs will be red, swollen and congested. At this time, you must pay more attention to hygiene to avoid infection, so you cannot bath. If your dog smells bad, you can wipe it with a wet towel or clean it with dry cleaning powder.

2. Dogs may bark randomly when they are in estrus. At this time, the dog owner should play with them as much as possible to consume their energy and distract their attention.

3. During the estrus period, the mood is not very stable. Try to go out as little as possible to avoid causing trouble. When going out, be sure to keep your dog on a leash to prevent emergencies.
