Understanding Your Dog’s Heat Cycle
As a caregiver, you play an integral role in the well-being of your pet. One way you can support your female dog is by understanding her heat cycle. This biological process is akin to human menstruation, although it occurs less frequently—typically twice a year. The heat cycle is divided into four stages, each with its unique characteristics and duration.
The Four Stages of the Canine Heat Cycle
-
Proestrus: This initial stage lasts between 7 to 10 days. During this phase, your dog’s vulva may become swollen, and she may exhibit bloody discharge. However, she will not be receptive to male dogs.
-
Estrus: This is the period when your dog is fertile and willing to mate. It lasts between 5 to 9 days. The discharge changes to a lighter color, and your dog may show ‘flagging’ behavior—lifting her tail up and to the side.
-
Diestrus: This stage can last between 60 to 90 days. If your dog has mated, this is the phase where pregnancy occurs. If not, it’s a period of rest.
-
Anestrus: This is the longest phase of the heat cycle, lasting between 100 to 150 days. During this period, your dog’s reproductive system is inactive.
Below is a table summarizing the stages:
| Stage | Duration | Characteristics |
|---|---|---|
| Proestrus | 7-10 days | Swollen vulva, bloody discharge |
| Estrus | 5-9 days | Lighter discharge, ‘flagging’ |
| Diestrus | 60-90 days | Pregnancy or rest |
| Anestrus | 100-150 days | Reproductive system is inactive |
Spotting Signs of Your Dog’s Heat Cycle
As a vigilant caregiver, you should be able to identify when your dog is in heat. Here are some signs:
- Swelling of the vulva
- Bloody or straw-colored discharge
- Increased urination
- Unusual behavior such as restlessness or clinginess
- Tail ‘flagging’
Managing Your Dog’s Heat Cycle
Managing your dog’s heat cycle can be a bit tricky, but here are some tips:
- Monitor her behavior closely for any changes

- Use doggie diapers to manage the discharge
- Consult your vet if you notice any abnormalities
