Heat Cycles In Female Dogs

Female dogs go through heat cycles, also called estrus. These cycles happen twice a year on average. Understanding these cycles helps explain male dog behavior during this time.

During heat, female dogs show signs that they are ready to mate. These signs affect how male dogs act around them.

Timing And Duration

A female dog's heat cycle usually lasts about three weeks. The cycle has different stages, each with its own timing and changes.

1. Proestrus: This stage lasts 7 to 10 days. The female may have a swollen vulva and bleeding.
2. Estrus: Lasts 5 to 9 days. The female accepts males and can get pregnant.
3. Diestrus: Lasts about 60 days. The female stops accepting males.
4. Anestrus: This is the resting period before the next cycle begins.

Physical Changes

Physical changes in female dogs during heat signal males to show interest. These changes can include visible and behavioral signs.

Discharge	Blood-tinged fluid is released, especially during proestrus.
