It is lined with a mucous membrane that is traversed by a network of blood vessels and nerves. This mucous membrane is susceptible to inflammatory conditions, which are referred to as rhinitis. If the inflammatory conditions spread to the sinuses, it is called sinusitis.   \n\nRhinitis and sinusitis can be triggered by a variety of factors. Infections by viruses, bacteria, or fungi are common causes. Viral pathogens include canine parainfluenza virus and canine adenovirus. Bacterial infections can occur primarily or secondarily to viral infections. Fungal infections, such as those caused by Aspergillus, are rarer but particularly significant in certain dog breeds.    \n\nAllergy is another common cause of rhinitis in dogs. Inhalant allergens such as pollen, house dust mites, or molds can trigger allergic rhinitis. Environmental factors such as smoke, dust, or chemical irritants can also irritate and inflame the nasal mucosa.  \n\nAdditionally, anatomical anomalies, such as narrowing of the nasal passages or polyps, as well as traumatic injuries to the nose, can lead to rhinitis and sinusitis. Tumors in the nasal cavity or sinuses can also play a role.

The discharge may come from one or both nostrils. Chronic cases can lead to crusting around the nostrils.  \n\nSneezing is another common symptom and can be accompanied by nosebleeds in severe cases. Some dogs also show swelling in the area of the nasal cavities or around the eyes, indicating a spread of the inflammatory conditions to the sinuses. \n\nAffected dogs may show respiratory sounds such as Snoring or rattling, especially if the nasal passages are narrowed. In severe cases, respiratory distress may also occur. \n\nIn chronic or severe infections, systemic symptoms such as Fever, loss of appetite, or lethargy may occur, indicating a general impairment of the dog's well-being.","zusammenfassung":"Rhinitis and sinusitis in dogs are inflammatory conditions of the nasal mucosa and sinuses. These diseases can be triggered by infections with viruses, bacteria, or, less commonly, fungi like Aspergillus. Allergies to pollen, dust mites, or molds, as well as environmental factors like smoke and dust, can also be causes. Anatomical anomalies or tumors in the nasal cavity are also possible triggers.   \n\nTypical symptoms include sneezing, nasal discharge, congested nasal passages, and respiratory distress. Diagnosis is made through a veterinary examination, possibly supported by X-rays or CT scans, and rhinoscopy for sample collection. Laboratory tests can help determine the exact cause.  \n\nTreatment depends on the cause. Bacterial infections require antibiotics, while viral infections are usually treated supportively. Allergic rhinitis can be treated with antihistamines or corticosteroids. For fungal infections, specific antifungals are required, and surgical interventions may be necessary to remove tumors or polyps.   \n\nThe prognosis varies depending on the cause and severity, with acute infections often being well treatable. Chronic or allergic forms may require long-term treatment. Preventive measures include minimizing exposure to irritants and allergens, regular veterinary check-ups, and a healthy lifestyle. Vaccinations against certain viruses can also be helpful.   ","diagnose":"The diagnosis of rhinitis and sinusitis begins with a thorough clinical examination by the veterinarian. A thorough medical history, including questions about the duration and type of symptoms, can provide important clues to the underlying cause. \n\nFor further clarification, imaging techniques such as X-rays or computed tomography (CT) of the nasal cavities and sinuses can be used. These can help identify anatomical anomalies, foreign bodies, or tumors. \n\nAn endoscopic examination of the nasal cavity, rhinoscopy, allows direct visualization of the nasal mucosa and the collection of samples for histopathological examination. This can help identify infectious agents or tumor cells. \n\nAdditional laboratory tests, such as blood tests or cultures of nasal discharge, can be performed to determine the type of infection and plan appropriate therapy.","behandlung":"The treatment of rhinitis and sinusitis in dogs depends on the underlying cause. For bacterial infections, antibiotics are usually used. The choice of antibiotic is based on the results of culture and sensitivity tests.  \n\nFor viral infections, treatment is usually supportive, as antibiotics are ineffective against viruses. Support may include providing a warm, humid environment and administering mucolytic medications to facilitate nasal discharge. \n\nFor allergic rhinitis, antihistamines or corticosteroids may be used to control the inflammatory conditions. In some cases, hyposensitization therapy may be considered. \n\nFor fungal infections, specific antifungals are required, which often need to be administered over a longer period. Surgical interventions may be necessary to remove foreign bodies, polyps, or tumors. ","prognose":"The prognosis for dogs with rhinitis and sinusitis depends on the cause and severity of the condition. Acute viral or bacterial infections usually respond well to therapy, and symptoms often resolve within a few weeks. \n\nChronic or allergic rhinitis can be more difficult to control and may require a long-term management strategy. For fungal infections or tumors, the prognosis may be more guarded depending on treatment efficacy and disease progression. \n\nIn general, the prognosis is better if the condition is diagnosed and treated early. Regular veterinary follow-up is important to prevent relapses and maintain the dog's quality of life.

The most important research advance is that these diseases are no longer classified solely by symptoms such as nasal congestion, secretion, or pressure, but by biological inflammatory patterns. Particularly important are the mucosal barrier, the microbiome, local biofilms, and different immune responses, such as type 2 inflammation.

What are rhinitis and sinusitis?","antwort":"Rhinitis is an inflammatory condition of the nasal mucosa, while sinusitis affects the paranasal sinuses. Since both mucous membranes are anatomically connected, the conditions often occur together (rhinosinusitis). They can be acute or chronic.  "},{"frage":"2. What are the causes?","antwort":"Common causes include viral (parainfluenza, canine distemper), bacterial, and fungal infections (especially Aspergillus), foreign bodies like grass awns, dental root diseases with oronasal fistula, tumors of the nasal cavity, allergies, and traumas. Idiopathic, chronic lymphoplasmacytic rhinitis also occurs. "},{"frage":"3. What symptoms do affected dogs show?","antwort":"Typical symptoms include nasal discharge (clear, mucous, purulent, or bloody), sneezing, snoring sounds, nosebleeds, and respiratory distress. In unilateral rhinitis, foreign bodies, fungal diseases, or tumor diseases are particularly likely. Chronic courses are often accompanied by weight loss and a reduction in general condition.  "},{"frage":"4. How is the diagnosis made?","antwort":"A thorough examination includes nasal X-rays or, preferably, CT, rhinoscopy with flushes and biopsies, as well as cytological, histological, and microbiological examination of the material. Dental control and, if necessary, endoscopy of the nasopharynx are important additions. "},{"frage":"5. How is rhinitis treated?","antwort":"Therapy depends on the cause. Bacterial infections are treated with antibiotics, fungal infections with topical clotrimazole infusion under anesthesia. Foreign bodies are removed rhinoscopically with fine forceps. Chronic idiopathic forms are treated with corticosteroids, inhalation therapy, and mucolytics.   "},{"frage":"6. What is nasal aspergillosis?","antwort":"Nasal aspergillosis is a fungal infection with Aspergillus fumigatus, which primarily occurs in middle-aged, mesocephalic dogs. Characteristic symptoms include unilateral, bloody nasal discharge, pain on the nasal bridge, and depigmentation of the nose. Therapy involves a one-hour topical clotrimazole infusion.  "},{"frage":"7. What signs indicate a nasal tumor?","antwort":"Nasal tumors primarily occur in older, dolichocephalic dogs. Typical symptoms include unilateral nasal discharge, progressive facial deformation, nosebleeds, and epiphora. Adenocarcinomas and carcinomas of other mucosal cells are the most common tumors. Diagnosis and therapy require CT and a targeted biopsy.   "},{"frage":"8. How are foreign bodies removed?","antwort":"Grass seeds, awns, or hay particles are removed rhinoscopically with fine forceps under anesthesia. Additional flushing is often necessary to dislodge deeply embedded particles. If a foreign body remains undetected, it can migrate for weeks and cause chronic inflammatory conditions and abscesses.  "},{"frage":"9. What role do teeth play in chronic rhinitis?","antwort":"Periodontitis of the maxillary canine teeth, in particular, can lead to oronasal fistulas and chronic rhinitis. A thorough dental examination with dental X-rays should be performed for any chronic unilateral rhinitis. Treatment of the dental disease is then crucial.  "},{"frage":"10. What is the prognosis?","antwort":"Acute rhinitis of infectious origin usually heals well. Aspergillosis heals after topical therapy in about 80 percent of cases if bone lysis is not too extensive. Chronic idiopathic rhinitis often requires lifelong treatment. Tumor-related forms have a more guarded prognosis, which varies depending on the tumor type.
