The estrous cycle is the cycle of a non-pregnant female mammal that goes through a luteal phase and a follicular phase. Estrus is the period in which an animal will stand to be bred, and is part of the follicular phase of the estrous cycle. An easy way to remember it is that estrous is an adjective and estrus is a noun. Thus, estrous refers to the entire cycle, whereas estrus just refers to the phase in which the animal can get pregnant. Usage: The female chimpanzee can get pregnant because she is in estrus. The female chimpanzee can get pregnant in this phase of her estrous cycle.

A female dog's heat cycle or estrus typically lasts around 2-4 weeks. This cycle is divided into four stages: proestrus, estrus, diestrus, and anestrus. During the estrus stage, which is when she is fertile, the female dog may actively seek out males for breeding.
Same amount for a beef cow: estrus is around 24 hours. Estrous is 21 days long.
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.
Rabbits do not have a typical estrus cycle as other mammals. Rabbits are stimulated to ovulate by the mating act, and as such, can be ready to mate and conceive again as soon as they drop each litter -- approximately every 30 days.
Anestrus or Diestrus. Proestrus is when the female is about to go into estrus, and Metestrus is the period before Diestrus and after Estrus which the female goes out of heat and ovulation ends.
The duration of a pony's season, or estrus cycle, typically lasts about 5 to 7 days. However, the entire reproductive cycle can take approximately 21 days, during which the mare will have multiple phases including estrus and diestrus. After the season ends, the mare will generally return to estrus in three weeks if not bred. Factors such as health, age, and environmental conditions can influence these cycles.
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 in a cow or heifer only lasts for ~24 hours.
