You should go to your veterinarian to do a general scan of your dog.
In senior dogs it is very common to have affections of some of the systems. Panting could be due to heart or respiratory failure.
In any case, your veterinarian will be able to better assess your dog's condition through a review and, if needed, through the necessary diagnostic tests.
All the best for you and Rico.
