A dog can get a sinus infection just like a person. Sinuses are cavities located in a dog's skull, which can be prone to infection. When an infection occurs, these cavities will fill with fluid, and passages within the nasal cavity become irritated and inflamed. As a result, dogs with a sinus infection may have symptoms of coughing, sneezing, nasal discharge or a runny nose to expel this fluid (mucus). It is possible for sinus infections to be caused by a number of factors, including fungus, virus or bacteria.
Determine potential irritants within your home that may be causing a sinus infection. It's possible to introduce new substances in your home or yard that create allergic sinusitis. For example, air fresheners, perfumes, cigarette smoke, mould or excessive amounts of dust may trigger infection. Treating houseplants with insect sprays, or using pesticides outdoors could bring on a sinus infection in dogs. Increased pollen production during the spring or fall months may be a contributing factor to a sinus infection. Change any one of these conditions, and your dog may make a speedy recovery.
Take appropriate steps when possible to relieve sinus congestion, and make your dog more comfortable. Be sure pets have sufficient water to drink. Warm chicken broth, or mix bouillon in warm water, and pour it over your dog's dry food to provide additional water in its diet. If your pet sleeps in one particular location all the time, run a humidifier or vaporiser while it sleeps. This will moisten a dry nose and help relieve congestion. Depending on the cause of the sinus infection, it may clear up in just a few days without requiring medical attention. Don't ever try to treat your pet with medicine meant for humans.
Notify a vet if you still have cause for concern, the situation worsens, or your dog has a bloody nose. A bloody nose could be an indication of a more serious condition. A sinus infection can cause lack of appetite and a lower energy levels, in addition to congestion. It's possible for a dog to have a virus infection, which generally lasts only a short time, and can't be treated with antibiotics.
Follow all instructions and give your dog any medications provided by your vet. If the situation warrants it, a vet may perform a thorough examination, including sinus cavity X-rays. Your vet may prescribe anti-fungal medication or antibiotics, depending on the cause of the infection.
