Your cockapoo is in heat how long does it last?

A cockapoo in heat typically goes through a cycle that lasts about 2 to 3 weeks. The heat cycle consists of four stages: proestrus, estrus, diestrus, and anestrus. The most fertile phase, estrus, usually lasts around 5 to 10 days when she is most receptive to mating. It's important to monitor her behavior and keep her away from male dogs during this time to prevent unwanted mating.
