Dogs enter the senior stage when they are over 7 years old, and at this stage the dog’s heart and lung function declines, so panting can occur. Therefore the owner should not take the dog for strenuous exercise, otherwise it will lead to breathing difficulties and stamina, and generally take the dog out for a walk every day. If it is caused by lung disease, it is recommended that the owner take the dog to the hospital for examination to determine whether there are lung nodules, lesions, etc. Especially after the dog has entered old age, dogs are more likely to suffer from heart disease.
