Here's why it's unusual and what you should do:
* Normal Cycles Stop Around 6-8 Years: Most female dogs go through their final heat cycle between 6 and 8 years old. They then enter a stage called "menopause" and no longer cycle.
* Potential Causes of Late Cycles: While it's not the norm, there are a few reasons why a 15-year-old might still have cycles:
* Hormonal Imbalance: Changes in hormone levels, especially estrogen, could be contributing to these late cycles.
* Underlying Health Condition: Medical conditions like uterine infections, tumors, or other problems can sometimes affect hormone production and cause continued cycling.
* Importance of Vet Visit: It's very important to take your dog to the veterinarian as soon as possible. The vet can:
* Examine Your Dog: They'll check for any signs of infection, tumors, or other abnormalities.
* Run Tests: Blood work and ultrasounds can help identify hormonal imbalances or underlying medical conditions.
* Recommend Treatment: Depending on the cause, treatment might include hormone therapy, medication, or surgery.
Key Takeaway: Don't ignore these late cycles. They could be a sign of something serious that needs attention. Your dog's health is important, and a vet visit can help determine the cause and provide the best treatment options.
