What is the name of heat in dogs? - in detail
Heat in dogs, commonly referred to as "heat cycle" or "estrus," is a critical phase in a female dog's reproductive life. This period is characterized by hormonal changes that prepare the body for potential mating and pregnancy. The heat cycle typically occurs twice a year, although this can vary depending on the breed and individual dog.
During the heat cycle, which lasts about 21 days, dogs experience several distinct stages:
-
Proestrus: This is the initial phase of the heat cycle, lasting approximately 9 days. During proestrus, the female dog's body prepares for ovulation and potential mating. The vulva may swell, and there might be a slight bloody discharge. However, the dog will not accept a male during this stage.
-
Estrus: Also known as standing heat, estrus is the phase when the female dog is most receptive to mating. This stage usually lasts 9 days but can vary. The vulva remains swollen, and the discharge may become more watery. It's during this time that ovulation occurs, typically around day 10-14 of the cycle.
-
Diestrus: Following estrus, the diestrus stage begins, lasting about 60-90 days. If mating has occurred and fertilization is successful, pregnancy will develop during this phase. Hormonal changes prepare the uterus for implantation of the embryos.
-
Anestrus: The final stage of the heat cycle is anestrus, a period of sexual inactivity that can last 100-150 days. During this time, the female dog's reproductive system is at rest, preparing for the next heat cycle.
Understanding the heat cycle in dogs is crucial for responsible pet ownership, particularly if you do not wish to breed your dog. Spaying (ovariohysterectomy) can prevent unwanted pregnancies and reduce the risk of certain reproductive health issues. Consulting with a veterinarian is essential for managing a female dog's heat cycle effectively.
