Use plain descriptions
If there is visible fluid, describe what you can actually see rather than naming an infection or allergy. VCA discusses excessive, thick or discolored mucus as reasons to call a veterinarian. PDSA's checklist also advises calling about discharge and congestion.
A description can help the veterinary team ask the next question. It does not tell you which disease, injury or irritation is present, and this site does not list diagnoses for you to choose from. The same observation can require context and examination.
PDSA advises contacting a veterinarian for frequent or distressing sneezing and for other signs such as a runny or bleeding nose, pain or facial swelling. Report what you noticed without deciding which detail matters most yourself. Contact the vet immediately for trouble breathing.
This page does not tell you to insert anything into the nose, flush it, give medicine or apply a product. Ask the veterinary team what they need from you. Do not let making a detailed note delay contact.
