Here's what's typical:
* Average Heat Cycle: Most dogs experience a heat cycle that lasts around 2-3 weeks (14-21 days), with bleeding typically lasting around 7-10 days.
* Variation is Normal: The length of a heat cycle and bleeding can vary significantly between breeds, individual dogs, and even from cycle to cycle in the same dog.
* Beyond 14 Days: While a longer period of bleeding is not the norm, it's important to consider factors like breed, age, and overall health.
* Potential Causes: Bleeding beyond 14 days could be a sign of:
* Uterine infection: This can cause prolonged bleeding and other symptoms like lethargy, loss of appetite, and fever.
* Tumors: Uterine tumors can also lead to abnormal bleeding.
* Other health issues: Other medical conditions could be the culprit.
If your dog's bleeding lasts longer than 14 days, it's crucial to consult with your veterinarian immediately. They can determine the underlying cause and recommend appropriate treatment.
