Treatments For Sinusitis In Dogs

If your veterinarian suspects your dog may be suffering from sinusitis, they’ll carry out a full physical examination. Due to the variety of potential causes, the vet may suggest a number of other tests, including blood work and even a tissue biopsy.

If the vet suspects that a foreign body in the nose is the root cause, then your dog will need to have an X-ray.

Once the vet confirms the diagnosis, the course of treatment will depend entirely on the cause of the condition. If a bacterial infection is the cause, then the vet will likely prescribe a course of antibiotics. In a case that involves a foreign body lodged in the dog’s nose, the vet may need to perform a surgical procedure.

While your dog recovers at home, vets will often recommend the use of a humidifier to help keep the dog’s nasal passages free of mucus.
