So my dog has been given Nova D.O.C shots for three days, no improvement. The clear nasal discharge is still there, he will open his mouth from time,maybe to breathe, lethargic, nose swollen. The blood test shows slightly increase in leukocyte and neutrophil. His nose colour has changed from its original brown to a lighter colour. Will it possibly be aspergillosis if his nasal discharge is clear and from both nostrils?
