If you have a female dog, understanding her reproductive cycle can help you provide better care and prevent unwanted pregnancy. Common signs of heat include swelling of the vulva, vaginal discharge, frequent urination, and changes in behavior. Some dogs may become more affectionate or restless, while others show only subtle symptoms.

The dog heat cycle typically lasts around two to three weeks, although the duration and frequency vary from one dog to another. During this period, keep your dog on a leash, avoid off-leash parks, and prevent contact with unneutered males. Remember that visible symptoms and calendar estimates cannot reliably identify the exact fertile days.

If you notice unusual discharge, excessive bleeding, or signs of illness, consult a veterinarian. Spaying is also worth discussing if you want to prevent future heat cycles and unwanted pregnancies.
