What Is a Dog's Heat Cycle?
The heat cycle, also called estrus, is a recurring period in a female dog’s life when she becomes fertile and can mate. It is a natural biological process that usually starts when a dog reaches puberty, which can vary depending on the breed and individual dog. Typically, smaller breeds enter heat earlier (around 6 months of age), while larger breeds may take up to 18 months to experience their first heat cycle.
During estrus, your dog will undergo hormonal changes that prepare her body for reproduction. These changes manifest in various ways, including behavioral shifts, physical signs like swelling of the vulva, and bleeding. Understanding the nuances of this cycle can help you support your pet during this time while also preparing for potential responsibilities like pregnancy or preventing unwanted litters.
Key Features of the Heat Cycle
- Occurs approximately every 6-12 months, depending on the breed.
- Divided into four distinct phases: proestrus, estrus, diestrus, and anestrus.
- Lasts for an average of 2-4 weeks.
- Characterized by hormonal and behavioral changes.
When Does a Dog First Go Into Heat?
A female dog’s first heat typically occurs between 6 to 24 months of age. Smaller breeds like Chihuahuas and Dachshunds may experience their first cycle at around 6 months, while larger breeds like Great Danes may not go into heat until they are closer to 18 or 24 months old. It’s essential to monitor your dog’s behavior and physical signs during this developmental phase to understand her unique cycle.
How Long Does a Dog Bleed While in Heat?
The duration of bleeding during a dog’s heat cycle typically lasts around 7 to 10 days, though this can vary based on individual factors like breed, age, and overall health. Bleeding occurs during the first phase of the cycle, known as proestrus, and is one of the most noticeable signs that your dog is in heat. The intensity of bleeding may also differ, ranging from light spotting to heavier flows, depending on the dog.
Factors That Influence Bleeding Duration
- Breed: Larger breeds may experience longer or heavier bleeding compared to smaller breeds.
- Age: Younger dogs in their first heat cycle might bleed for a longer duration than older dogs.
- Health: Underlying medical conditions can impact the length and intensity of bleeding.
- Environment: Stress and lifestyle factors may also play a role.
Signs to Watch For
While bleeding is normal, it’s essential to monitor your dog for any unusual symptoms. If the bleeding lasts longer than 14 days, is excessively heavy, or is accompanied by signs of illness like lethargy or loss of appetite, consult your veterinarian immediately. Timely intervention can prevent potential complications.

1. Proestrus
This is the initial phase of the heat cycle, lasting roughly 7-10 days. During this time, the dog’s body begins to prepare for mating. Key signs include:
- Swelling of the vulva.
- Bloody discharge.
- Behavioral changes like increased clinginess or restlessness.
2. Estrus
Estrus is the fertile phase of the cycle, lasting about 5-7 days. This is when ovulation occurs, and the dog is most receptive to mating. Signs include:
- Reduced bleeding or discharge changes to a lighter color.
- Increased interest in male dogs.
- Flagging behavior (raising the tail).
3. Diestrus
The diestrus phase lasts 10-14 days and marks the end of the fertile period. During this time, hormonal levels stabilize, and the dog’s body either prepares for pregnancy or returns to normal if no mating occurred.
4. Anestrus
Anestrus is the resting phase, lasting several months. During this time, the dog’s reproductive system resets in preparation for the next cycle.
