When are the menstrual cycles for a corgi?

Corgis, like most dogs, typically have their first heat cycle around six months to a year of age. They usually go into heat twice a year, with cycles lasting about 2 to 3 weeks. During this time, they may exhibit behavioral changes, such as increased urination and a desire to roam. It's important for pet owners to monitor their corgi during this period to prevent unplanned breeding.
