The estrus cycle of a Cavalier King Charles Spaniel typically lasts about 2 to 3 weeks. This cycle occurs approximately every six months, although it can vary among individual dogs. The cycle consists of four stages: proestrus, estrus, diestrus, and anestrus, with the most fertile period occurring during the estrus stage. It's important for owners to monitor their dog's behavior during this time for any signs of heat and potential breeding.
The length of estrous for cattle is approximately 21 days. The estrus period last about 18 hours.
Estrus Records was created in 1990.

The estrus cycle consists of four main stages: proestrus, estrus, metestrus, and diestrus. Proestrus is the period before ovulation, characterized by the growth of follicles. Estrus is the mating period when the female is receptive to males. Metestrus is a transition stage after ovulation, and diestrus is a period of sexual inactivity if fertilization did not occur.
