I believe that anyone who raises dogs will be involved in the issue of estrus and mating. When a dog reaches sexual maturity at a certain age, it will begin to go into estrus and seek mating. Nowadays, more and more people are raising dogs as pets. Most families keep one dog. Therefore, when a dog is in heat, pet lovers should go out of their way to find a mate for the dog, and also prevent the dog from getting into trouble at home. Dogs are messing around outside, so we dog owners must know about dog heat and mating.

Under normal circumstances. Female dogs will go into heat once before they are 1 year old. From then on, they will go into estrus twice a year, usually once in spring from March to May and once in autumn from September to November. Generally, the best first mating age for female dogs is 1 or 5 years old (it is appropriate to mate during the second estrus). When a dog is in heat, special physical and behavioral signs will occur.

There are 4 stages of dog estrus:

1. Pre-estrus: It is the preparation stage for estrus, which lasts about 7-10 days. The reproductive system begins to prepare for ovulation. Externally, the vagina becomes gradually congested and swollen, with mucus mixed with blood flowing out. The frequency of urination increases but the amount is small. However, male dogs are not allowed to lie on their backs at this time.

2. Estrus: It is the period when the signs of estrus are most obvious and mating is accepted. The vagina begins to bleed, which lasts about 15 days. The early stage of vaginal enlargement gradually subsided, and the dripping of bloody mucus decreased, and the color changed from bright red to light red. 2-3 days after the estrus period, the female dog begins to ovulate, which is the best time for mating.

3. Late estrus. The swelling of the vulva subsided and gradually returned to normal.

4. Anestrus period. The reproductive organs enter a state of inactivity. It usually lasts about 3 months, and then enters the next proestrus. To put it bluntly, it is a period of time when nothing happens.

Don't take a shower when you're in heat. But be careful to clean your dog’s vagina to avoid infection. Dogs may develop anorexia due to irritability. To enhance its resistance. It's better to get more delicious food to feed it. Because the female dog will lose weight quickly during estrus, and her temper will become a little strange. You will become less courageous. Tempers can get bad. He will also make trouble with you and use your arm as a stick. HOHO. If you don't plan to mate your baby. Then avoid contact with male dogs when they are in heat. Do good home hygiene. You can wear menstrual pants.

Male dogs are in estrus: Dogs begin to have the ability to reproduce around 11 months after birth. The best age for a male dog to be bred for the first time is 2 years old. Male dogs do not have an obvious estrus period. During the breeding season when the female dog is in estrus, the male dog's testicles enter a functionally active state. When he approaches the female dog in estrus, he smells the special odor of the female dog in estrus, which can cause excitement to complete mating. To put it bluntly: a male dog is always ready
