Our expert says:
Ooh, they are so many possibilities, I can only guess. If the gums are very pale, she may have severe anaemia, and that makes dogs tired and causes panting. Boxers also have heart problems which can cause similar symptoms. Any disease that causes excessive lethargy and tiredness may also contribute. As you can see, I can only guess. The symptoms are not specific to any particular disease.
