When does a min pin have her first period?

A Miniature Pinscher (min pin) typically experiences her first heat cycle, or period, between 6 to 12 months of age. However, this can vary based on individual development and genetics. It's important for owners to monitor their dog for signs of heat, such as swelling of the vulva and behavioral changes. If you have concerns about your min pin's reproductive health, consulting a veterinarian is advisable.
