PROESTRUS HEAT PHASE:
This is when male bulldogs are interested in a female bulldog, but she is not ready to mate.
- The vulva swells and there may be bloody vaginal discharge
- Lasting for about 1-2 weeks
ESTRUS HEAT PHASE:
This is the time when a female bulldog is ready and willing to mate, and this is what most owners call “heat.”.
- The bleeding usually stops or lightens
- Lasting for about 5-10 days but can be anywhere from a few days to 3 weeks
The estrus phase is the only stage she can get pregnant.
DIESTRUS HEAT PHASE:
This comes after mating; at this point, your Frenchie is either pregnant or not, and her hormone levels return to normal.
- Lasting 2-4 months
ANESTRUS HEAT PHASE:
This is a period when there is no attraction between male and female bulldogs. This is the resting stage, lasting until the next cycle begins
- lasting for about 4-5 months, but could last longer
“IN HEAT”: Bulldogs and French bulldogs in heat usually mean that they are in Proestrus or Estrus.
