A dog’s heat cycle typically lasts 2 to 4 weeks, though it can vary a bit depending on the dog breed. During that time, you might notice: Swelling of the vulva, bloody or straw-colored discharge, more frequent urination, behavioral changes like being more affectionate or restless. The discharge tends to be heavier in the first week or so and then tapers off. If it’s your dog’s first heat, it can be a bit unpredictable, but it gets more regular with time. If you’re not planning to breed her, it’s worth talking to your vet about spaying, it can prevent unwanted litters and reduce health risks like certain cancers and infections. Dogs don’t have periods in the same way humans do, but they do go into heat, which is part of dog heat cycle. This usually happens about twice a year. for more queries consult vet at petyaari pet clinic.
Most dogs go into heat about twice a year, although this can vary by breed, age, and individual dog. Smaller breeds might go into heat three times a year, while larger breeds may only cycle once a year.
The heat cycle itself typically lasts 2 to 4 weeks, though around 21 days is the average. It’s broken down into four phases, but the parts you’re most likely to notice are:
- Proestrus (about 7–10 days):
This is the beginning stage. The vulva starts to swell, and you’ll likely see bloody discharge. She may urinate more often and attract male dogs, though she’s not ready to mate yet. - Estrus (about 5–10 days):
This is when your dog is fertile. The discharge may become lighter—more pink or straw-colored—and she may now be receptive to mating. This is the period where accidental pregnancies can happen if you’re not careful.
After estrus, she enters diestrus, which is essentially the “cool down” period, and then anestrus, the resting phase until the next cycle.
During her heat, it’s important to keep a close eye on her. Some dogs become clingy or anxious; others might seem more aloof. Keeping her indoors or securely leashed when outside is key male dogs can be very determined, and females can be just as sneaky.
So to sum up: dog “periods” (heats) usually last around 2–3 weeks, and you’ll see a mix of physical and behavioral signs. If you ever feel unsure, consult at petyaari pet clinic.
