Dog owners often find it difficult to recognize their dogs' heat period and are not really aware of how to deal with them during that time. Dogs being in heat is a very normal phenomenon, just as menstruation in humans. This phenomenon is also known as the canine estrous cycle. Male dogs do not go into heat but are surely affected by the female dogs around them during this period. Female dogs go through a lot of behavioral changes during this time and need to be handled appropriately.
Canine Estrous Cycle Stages
Like the menstrual cycle in humans, the canine estrous cycle has different stages that vary in duration, and dogs go through different changes during this time. The beginning of the estrous cycle indicates that the female dog has reached a stage of sexual maturity, also known as puberty. This cycle has four stages - proestrus, estrus, diestrus, and anestrus. The duration and frequency of the cycle depend upon the breed and age of the dog in heat.
Proestrus
This is the first stage, which generally lasts from the first to the ninth or tenth day of the cycle. During this stage, the female dog bleeds through her vaginal area and the male dogs are attracted to her due to the discharge. However, during this stage, female dogs are non-receptive. They usually tuck their tail between their legs when a male dog approaches.
Estrus
This is a crucial stage wherein the female starts ovulating, becomes receptive to the pursuing male dogs, and allow breeding or mating. This stage can be recognized by the swelling of the vulva and bleeding. This stage lasts for approximately five to nine days. The female can be seen flagging her tail to attract male dogs.
Diestrus
This stage follows the mating period. If the female dog mates successfully, she will be pregnant. If she does not mate, some hormonal changes would occur with decreased vaginal discharge and receptiveness towards male dogs. The swelling of the vulva reduces and so does the bleeding.
Anestrus
In this stage of the cycle, the female dog undergoes no hormonal change and shows no interest towards mating. It is the time when her body prepares itself for the next estrous cycle. This stage lasts for about five to six months.

Dog owners who have female dogs should watch out for the following symptoms to recognize if their dog is in heat.

Apart from the above symptoms, you would also notice behavioral modifications like increased lethargy and laziness, aggressiveness towards other female dogs, increased need for attention and pampering, etc. Male dogs display a lot of aggression and excitement caused due to the odor of a female dog in heat. They may wander off in pursuit of the female or display restlessness and the urge to be around her.
Spaying
Spaying dogs can be useful for the prevention of various health risks like the development of mammary tumors, uterine infections, uterine cancer, and to avoid having too many litters.
