                                                          A colored discharge from the nasal area is typically due to infection. This may be due to a viral infection, a nasal infection from debris being lodged in the nose, a dental infection draining into the nose, bacterial infection or injury to the nasal area.
 For this symptom its a good idea to plan to see your vet.
