Symptoms of an upper respiratory infection typically include nasal discharge, sneezing, and coughing. If Hank is not feeling well, I recommend having him seen by a vet as soon as possible. Puppies are prone to viral and bacterial infections, intestinal parasites, and can decline rapidly if not treated appropriately. I hope all is well and am happy to answer any other questions you may have!
