What causes cat or dog nasal discharge?
Clear discharge can be normal and be based on exercise and environment but if your animal experiences increased discharge, especially if coloured then an infection is the most likely cause. This can be bacterial, fungal or viral depending on the situation. Foreign objects (grass, slivers, other) stuck in the nose can create irritation and infection and allergic disease is also possible. Bloody discharge is usually a traumatic situation but a mass in the nose is also seen on occasion. Getting a diagnosis may be very simple such as in some infections situations, or very complex in some foreign object situations or masses. Treatment varies depending on the cause of the problem. Any discharge that is different from normal should be assessed.
