Typical treatment for sinus problems in dogs includes avoiding allergens and administering anti-inflammatory medications, according to VetInfo.com. Some medicines may need to be given indefinitely if the allergen can't be identified and avoided. A blood test and allergen comparison panel can determine the cause of an allergic reaction.
The Merk Manual for Pet Health advises that using anti-inflammatory medicines for long periods of time may lead to digestive complications, such as stomach ulcers. Holistic treatments are an ideal way to boost the immune system and reduce unhealthy sinus symptoms. Biochemic tissue salts aid in relieving congestion, and the herbs Pulsatilla and licorice help reduce inflammation naturally.
