At what age do dogs reach menopause?

Menopause varies by individual: some dogs at 7–8 years, others never and still cycle when old. The ‘period’ is the heat phase, lasting about 1–2 weeks with bleeding each time.

Keep the area clean and wipe discharges. If you have no breeding plan, spay at the right time — it stops the bleeding and lowers reproductive-disease risk, extending life somewhat.
