At what age do female dogs stop their heat cycle? - briefly
Female dogs typically experience their first heat cycle between the ages of six and twelve months. The frequency and duration of these cycles can vary, but most dogs will continue to have regular heat cycles until they reach old age or are spayed.
At what age do female dogs stop their heat cycle? - in detail
Female dogs typically stop going into heat around the age of six or seven years old. However, this can vary significantly depending on several factors such as breed, size, and overall health. Smaller breeds often go into heat more frequently than larger breeds, which may result in a later cessation of the cycle. Additionally, spaying (surgical removal of the ovaries and uterus) can immediately stop the heat cycles regardless of age, as it eliminates the source of hormonal changes that trigger estrus. It's important to note that even after natural menopause, some female dogs may continue to exhibit behavioral changes or discharges associated with their previous heat cycles, although these are typically less intense and do not indicate a return to fertility. Regular veterinary check-ups can help monitor the reproductive health of your dog and provide guidance on when spaying might be appropriate.
