estrous
Ready to mate
Estrous describes the recurring reproductive cycle in most female mammals, or relates to estrus—the period of fertility and sexual receptivity within that cycle.
The estrous cycle in dogs occurs roughly twice a year.
The term appears mainly in veterinary and biological contexts.
Also spelled oestrous in British English.
