Here's why it's not about age:
* Natural Cycles: Female dogs naturally have heat cycles every 6-12 months, beginning around 6-12 months old.
* Spaying: Spaying is a surgical procedure that removes the ovaries and uterus, effectively ending heat cycles and preventing pregnancy.
* No Natural Menopause: Dogs don't experience menopause like humans do.
So, a Labrador will stop having heat cycles when she's spayed.
If you have a Labrador Retriever and are considering spaying, it's best to consult your veterinarian. They can help you decide when the right time is for your dog based on her individual health and lifestyle.
