However, here are some common signs of a female puppy in heat (estrus):
Physical Changes:
* Vulvar swelling: The area around the vulva becomes swollen and reddened.
* Bloody discharge: A bloody, often sticky discharge will appear from the vulva. This can range in color from bright red to brown or even clear.
* Restlessness: The puppy might be more energetic or agitated.
* Increased urination: This is due to hormonal changes affecting the urinary system.
* Changes in appetite: Some puppies might experience a decreased appetite during heat.
* Vocalization: Some puppies might whine or bark more than usual.
Behavioral Changes:
* Increased attention-seeking: The puppy might try to get closer to humans or other dogs.
* Mounting: The puppy might try to mount other dogs or objects.
* Aggression: Some puppies might become more aggressive towards other dogs, especially males.
* Increased marking: The puppy might urinate more frequently to mark her territory.
The duration of a heat cycle can vary, but it typically lasts around 2-3 weeks.
It's important to keep your female puppy on a leash when walking and prevent her from interacting with intact male dogs during this time to avoid unwanted pregnancy.
Again, these are just general signs. If you're concerned about your puppy, please contact your veterinarian for further advice and guidance.
