Understanding the Canine Heat Cycle
Just like humans, your beloved female dog will undergo a reproductive cycle. This is often referred to as the dog going ‘in heat’. This is a crucial stage in your pet’s life, which you, as her caregiver, need to understand and embrace.
- Proestrus: This is the first stage, lasting approximately nine days. You might notice some physical changes, like a swollen vulva and bloody discharge.
- Estrus: The second stage, also lasting about nine days, is when your dog is most fertile. Her discharge may lighten in color and she may display mating behaviors.
- Diestrus: After ovulation, your dog enters the diestrus stage. This can last up to two months. If she has mated, this is when pregnancy will occur.
- Anestrus: The final stage is a resting phase, before the cycle starts again.
Table 1. The Canine Heat Cycle
| Stage | Duration | Signs |

| Proestrus | 9 days | Swollen vulva, bloody discharge |
| Estrus | 9 days | Lighter discharge, mating behaviors |
| Diestrus | 2 months | – |
| Anestrus | – | Resting period |
Frequency of Heat Cycles
On average, most female dogs will go into heat twice a year, approximately every six months. However, this can vary greatly depending on breed and individual health.
- Small breeds may go into heat three or four times a year.
- Large breeds may only go into heat once a year.
- Some breeds, like the Basenji, are known to only go into heat once a year, typically in the fall.
Recognizing the Signs
As her caregiver, it’s essential that you learn to recognize the signs that your dog is going into heat.
- Swelling of the vulva
- Changes in behavior such as increased urination or increased affection
- Bloody or straw-colored discharge from the vulva
- Increased interest from male dogs
The Importance of Spaying
Unless you plan to breed your dog, spaying is highly recommended. Not only does it prevent unwanted pregnancies, but it also protects against certain health issues, such as mammary cancer and uterine infections.
Managing Your Dog’s Heat Cycle
When your dog is in heat, you’ll need to take some extra precautions.
- Limit her interaction with male dogs: This is crucial in preventing unwanted pregnancies.
- Keep her indoors as much as possible: This will also help to prevent pregnancies and protect her from male dogs who may become aggressive.
- Keep her comfortable: She may be feeling uncomfortable or anxious, so be sure to provide lots of love and comfort during this time.
