Dogs reach puberty between 6 and 24 months old, at which age female dogs will start having an estrous cycle. There are four stages of estrous: proestrus, estrus, diestrus, and anestrus. A dog in estrus, also known as being "in heat", can become pregnant during this 3- to 21-day period. [3]

The proestrus is relatively long at 5 to 9 days, while the estrus may last 4 to 13 days, with a diestrus of 60 days followed by about 90 to 150 days of anestrus.
This is the time at which female dogs will have their first estrous cycle, characterized by their vulvas swelling and producing discharges, usually lasting between 4 and 20 days. [80] [81] They will experience subsequent estrous cycles semiannually, during which the body prepares for pregnancy.
Dogs reach sexual maturity and can reproduce during their first year, in contrast to wolves at two years-of-age. Female dogs have their first estrus ("heat") at 6 to 12 months-of-age; smaller dogs tend to come into heat earlier whereas larger dogs take longer to mature.
