If her gums and tongue turned blue (cyanosis aka cyanotic), this is a sign of not getting enough oxygen. This can come from a heart problem, a tracheal issue like tracheal collapse, a severe allergic reaction, poor pulmonary perfusion (pneumonia, cancer, fluid around the lungs, etc) and much more. I would strongly recommend to take her to the vet for an exam to see if they can figure out what caused her to be cyanotic and hopefully prevent it from happening again. Lack of oxygen can be fatal if not immediately treated. I hope this helps!
