Heat in female dogs is a natural process that forms part of their reproductive cycle and is essential for fertility. Understanding how long a female dog’s heat lasts and the different stages it involves will not only help you manage and understand her behavior but also ensure her well-being during this period. That’s why today at Only Fresh, we’re sharing everything you need to know about it.
At what age does a female dog’s first heat occur?
The first heat in female dogs usually appears between 6 and 12 months of age, although in small breeds it may begin a little earlier, while in large breeds it may be delayed up to 18 months. This marks the beginning of their sexual maturity, and it’s important to watch for the first signs so you can meet their needs properly.
During their first heat, females may show more restless behavior, with changes in appetite and increased desire to interact with other dogs. This is completely normal, as their body is adjusting to new hormones. It’s recommended to monitor them carefully during this period to detect any irregularities or discomfort.
How long does heat last in female dogs?
Heat in female dogs generally lasts between 2 and 3 weeks, although it can vary depending on the breed and individual characteristics. During this time, they go through different phases in which hormone levels fluctuate, affecting their behavior and receptivity to mating.
Keep in mind that although bleeding usually lasts between 7 and 10 days, this does not necessarily indicate the end of the heat cycle. If you wonder how to know if your dog has finished her heat, pay attention to behavioral changes, such as reduced interaction with other dogs or the disappearance of signs of receptivity.
How often do female dogs go into heat?
On average, female dogs go into heat every 6 months, although some small breeds may have more frequent cycles. It is normal for a small female dog to come into heat every 3 months, while larger breeds may have cycles every 8 to 12 months. The regularity of the cycle is an important indicator of reproductive health.
If you notice that your dog has irregular or overly frequent heat cycles, consult your veterinarian to rule out hormonal or health issues. Proper tracking of her cycles will help you anticipate her needs and ensure her well-being.
Phases of the estrous cycle and behavioral changes in female dogs
1. Proestrus
The proestrus is the initial phase of heat and usually lasts 7 to 10 days. During this period, you’ll notice increased vaginal bleeding and swelling of the vulva, clear signs that the cycle has started. Although the female is not yet ready for mating, she will likely attract males due to hormonal changes.
Behavior before heat may include restlessness, increased need for attention, and slight changes in appetite. It’s important to provide a calm environment and avoid stressful situations during this stage.
2. Estrus
Estrus is the receptive phase when the female is willing to mate. This stage lasts between 5 and 10 days, and bleeding decreases or changes color to a lighter shade. You’ll notice that your dog may adopt mating postures and actively seek male attention.
This is the most fertile stage of the cycle, and if you are not planning on breeding, it’s crucial to take measures to prevent contact with males. Your dog’s behavior will become more intense and focused on her reproductive drive.
3. Diestrus
Diestrus follows estrus and can last up to 60 days. If the dog is not pregnant, hormone levels begin to stabilize and behavior returns to normal. During this stage, she may show calmness and reduced social activity.
In some cases, dogs may develop a false pregnancy during diestrus, showing signs such as milk production or mothering behavior toward objects. It’s important to consult your vet if this occurs to manage it appropriately.
4. Anestrus
Anestrus is the resting phase of the reproductive cycle, which can last between 4 and 6 months depending on the dog. During this stage, there are no signs of heat and the female’s body remains in a hormonal resting state. This period is ideal for veterinary check-ups to ensure her health.
Is it normal for my dog to bleed a lot during heat?
Moderate bleeding is normal during heat, especially in the early stages. However, if you notice excessive or prolonged bleeding, consult your vet immediately, as it could be a sign of an underlying problem, such as uterine infections or hormonal imbalances.
Remember that every dog is different, and the amount of bleeding may vary. The key is to watch for other signs, such as lethargy, fever, or evident discomfort, which could indicate a more serious health issue.
Tips for caring for your dog during heat
- Maintain proper hygiene: Keep your dog clean and comfortable during heat. Use special towels or dog diapers to prevent stains at home, and clean the area with safe products. This not only improves her comfort but also reduces the risk of infections.
- Avoid contact with other dogs: If you don’t want an unexpected litter, keep your dog away from males during heat. Walk her at quieter times and always use a leash to avoid unwanted encounters. Constant supervision is key to preventing accidental mating.
- Provide a calm environment: Heat can be stressful for your dog, so offer her a relaxed setting. Make sure she has a space to rest and avoid sudden changes in her routine.
- Consult your veterinarian: If you have questions about your dog’s heat cycle or notice unusual behaviors, don’t hesitate to see a vet. A professional can guide you and ensure your pet stays healthy during this stage.
