Please note that in some cases of risky heat, it is necessary to consult a veterinarian:
Heat that lasts more than 21 days
Heat that is too frequent (less than 4 months apart)
Heat that is too far apart (more than 8 months apart)
Heat that does not exist
To know if your dog is in heat, you must check that she has thicker vulvar discharge that is yellowish-white in color. The estrous cycle only occurs twice a year, and lasts on average about twenty days.
