The estrus cycle lasts on average 12-21 days, but maybe be as short as a few days to four weeks. The estrus period length varies widely between breeds and individual dogs. The length of a cycle varies widely, even for dogs of the same breed. If in doubt, assume the longer end of the range for the cycle length.
Female dogs do not have periods per se, but they do go through a regular heat cycle if they have not been spayed, or desexed. The average heat cycle for a dog is anywhere from 1 week to 4 weeks in length.The time between heat periods is usually around seven months but can vary from every 4 months to once a year.  Average times between heat periods is seven months but some dogs  can cycle as early as every 4 months, some once a year.    Lengths of heat cycles and intervals between cycles are different  for each dog but most dogs hit somewhere close to the averages.
