How often do dogs menstruate?

Answer 1

No, dogs do not menstruate, instead they go through "estrus" or "heat cycles" - meaning they are also fertile during these periods - approximately twice a year and last around 21 days. The dog may experience bloody discharge and increased urination. Some breeds bleed and a diaper may be necessary.

If you choose to have your dog spayed, she will not go through estrus.
