Typically, the cycle lasts around two to three weeks, but variations can occur based on breed and individual health. During this time, you may notice changes in behaviour, including increased affection or restlessness. It’s important to monitor these shifts closely.
Generally, the initial phase, known as proestrus, can last between 7 to 10 days. This is when certain physical signs become apparent, such as swelling of the vulva and a bloody discharge. Observing these signs can help you prepare for the upcoming stages.
The next phase, estrus, is when your pet is fertile and may actively seek a mate. This phase lasts about 5 to 9 days. During this time, the discharge typically lightens in colour and may even become less noticeable. Keeping your pet indoors or on a leash can prevent unwanted breeding.
After estrus, the cycle progresses to metestrus or dioestrus, lasting around 60 to 90 days if no mating occurs. During this phase, hormonal changes can lead to mood swings or changes in appetite. Regular veterinary check-ups can ensure your pet’s health remains optimal throughout this process.
Duration of Canine Heat Cycle
The heat cycle in female canines typically spans from 2 to 4 weeks. This timeframe consists of distinct stages: proestrus, estrus, diestrus, and anestrus. Understanding each phase helps in managing your pet’s health and behaviour effectively.
Phases of the Cycle
- Proestrus: Lasts about 7-10 days, characterised by swelling of the vulva and bloody discharge. During this time, your pet may attract male dogs but won’t be receptive.
- Estrus: Lasts approximately 5-14 days, the female becomes fertile and receptive to mating. Discharge may change to a lighter colour.
- Diestrus: This phase can last 60-90 days, regardless of whether the female is pregnant. Hormonal changes occur, and behaviour may return to normal.
- Anestrus: This is the resting phase, which can continue for several months until the next cycle begins.
Management Tips
- Keep your pet indoors during the initial stages to prevent unwanted mating.
- Monitor for signs of discomfort or unusual behaviour.
- Consider spaying if you do not plan to breed, as this can aid in behaviour management and health.

Understanding the Canine Estrus Cycle
The canine estrus cycle comprises four distinct stages: proestrus, estrus, diestrus, and anestrus. Each phase plays a significant role in a female dog’s reproductive health. Proestrus typically lasts around 7-10 days, characterised by swelling of the vulva and a bloody discharge. During this time, females attract males but are not yet receptive.
Estrus, the mating phase, follows proestrus and can last from 5 to 14 days, with the average being about 9 days. This is the period when the female becomes fertile and receptive to mating. Signs include a softer vulva and a change in discharge colour, often becoming lighter.
Diestrus and Anestrus Phases
After estrus, diestrus occurs, lasting around 60-90 days, regardless of whether mating took place. During this phase, the body prepares for a potential pregnancy. If conception does not occur, the female enters anestrus, which can last from several months to a year, depending on factors like breed and individual health. This is a resting phase where the reproductive system resets.
Monitoring and Care
It’s essential to observe your pet for any unusual symptoms throughout these stages. Keeping track of behavioural changes and physical signs can help in managing her health effectively. Regular vet check-ups during this cycle can ensure that any complications are addressed promptly, promoting overall well-being.
Typical Duration of a Dog’s Heat Cycle
The heat cycle in female canines generally spans 2 to 4 weeks. This timeframe can vary based on breed, age, and individual health. The cycle consists of four distinct phases: proestrus, estrus, diestrus, and anestrus.
During proestrus, which lasts about 7 to 10 days, the female may exhibit swelling of the vulva and increased urination. In this phase, she may attract males but is not yet receptive to mating.
The estrus phase follows, typically lasting 5 to 14 days, during which she becomes receptive. This is the time when mating can occur, and she may show behaviours indicating she is open to male attention.
Next is diestrus, lasting approximately 60 to 90 days. Even if mating does not occur, hormonal changes can still take place. This phase is crucial for those who are considering breeding, as it indicates whether the female is pregnant.
The final phase, anestrus, can last several months, during which the reproductive system rests. This cycle can repeat every six months, but variations can occur based on the individual. Keeping a close eye on your pet during this time will help you understand her specific patterns and needs.
Signs Indicating a Dog is in Heat
Watch for increased urination. During this phase, a female may urinate more frequently, marking her territory and signalling her availability to male dogs.
Observe behavioural changes. A normally calm dog may exhibit restlessness, increased affection, or even anxiety. Some dogs become more vocal, communicating their state to others.
Check for swelling in the vulva. This physical sign is a clear indication of heat, often accompanied by a change in colour, becoming more prominent and swollen.
Monitor discharge. A female in heat typically experiences a bloody discharge that may change in colour and consistency as she progresses through her cycle. This can vary from light pink to a more intense red.
Note interest from male dogs. If your female is attracting male attention, it’s a strong sign she is in heat. Males may show increased interest, attempting to get close to her.
Be aware of nesting behaviour. Some females may start seeking out quiet, comfortable spots to rest, showing instinctive behaviour as they prepare for potential mating.
Pay attention to changes in appetite. Fluctuations in eating habits are common. Some may lose interest in food, while others might eat more than usual.
Recognise the need for supervision. If your female is in heat, keeping a close eye on her is crucial to prevent unwanted mating. Consider securing her in a safe environment.
What to Expect During Your Dog’s Heat Cycle
Be prepared for a range of changes in your pet’s behaviour and physical state during her heat cycle. Typically, this phase can be divided into several stages, each with its own characteristics.
Behavioural Changes
In this time frame, you may notice your furry friend becoming more affectionate or, conversely, a bit moody. She might seek out more attention from you or other dogs, and you might even catch her marking her territory more frequently. This behaviour is completely normal and is driven by hormonal shifts.
Physical Signs
Watch for noticeable changes in her body. Swelling of the vulva and a bloody discharge are common indicators. The discharge may vary in colour and consistency, transitioning from bright red to a more straw-like hue as the cycle progresses. Keep an eye on her hygiene; regular cleaning can help prevent any irritation or infections.
During this time, restricting her access to male dogs is advisable to prevent unwanted mating. If you’re not planning to breed her, consider speaking to your vet about spaying. This can help her avoid the risks associated with future heat cycles.
Understanding these changes will help you support your pet during this natural process, ensuring she’s comfortable and well-cared for throughout her cycle.
