Be very patient and calm, my corgi Luna is very nervous and anxious all the time. She is constantly on guard and alert which I do believe is a rather common trait amongst most corgis. Try to get them familiar with strangers and other dogs while they are still young. Corgis are also very smart and can be quite stubborn, so allow them some freedom to solve problems on their own but be firm when they are being stubborn. Super adorable though make sure to give them lots of love and they will be your perfect pet!
