estrus
Reproductive receptivity period
Estrus is the period when a female mammal is fertile and receptive to mating—commonly called being in heat.
The term appears mainly in scientific and veterinary contexts: The dog's estrus cycle lasts about three weeks.
The adjective is estrous, as in estrous cycle.
Also spelled oestrus, especially in British English.
