Rabbit Rhinitis & Sinusitis: Vet Guide for 2025 🐇👃

Rabbit Rhinitis & Sinusitis: Vet Guide for 2025 🐇👃

By Dr Duncan Houston BVSc

📚 What Are Rhinitis & Sinusitis?

Rhinitis is inflammation of the nasal mucosa; sinusitis affects the air-filled cavities around the nose. Both can lead to nasal discharge, sneezing, and breathing issues in rabbits.

⚠️ Why It’s Important

• Rabbits are obligate nose-breathers—any blockage can cause distress.
• Can progress to otitis, pneumonia, or even systemic infection.
• Chronic cases cause poor quality of life and may reflect deeper issues.

🧠 Common Causes

• Snuffles (Pasteurella multocida): most common bacterial cause.
• Other bacteria: Bordetella, Pseudomonas, Staphylococcus.
• Dental disease: overgrown roots can deform nasal passages or block tear ducts.
• Foreign objects, trauma, allergies (rare), fungal infections, or neoplasia.

👀 Signs to Watch For

• Sneezing, nasal discharge (clear to purulent), crusting at nares or forepaws.
• Loud breathing, wheezing or open-mouth breathing—signs of severe distress.
• Conjunctivitis, tearing, runny eyes.
• Poor appetite, weight loss, lethargy—due to nasal discomfort or associated dental issues.
• Head tilt or ear signs may indicate middle ear spread.
• Nosebleeds can indicate deeper bacterial infection or dental involvement.

🔍 Diagnostic Workflow

• Complete history—onset, duration, home conditions, dental signs.
• Physical exam—assess nasal airflow, discharge, eye involvement.
• Dental exam to identify root overgrowth or abscess.
• Swabs for bacterial culture & sensitivity; cytology to determine inflammation.
• Radiographs initially, then CT or endoscopy to visualize sinuses and nasal passages.
• Blood tests may help rule out systemic infection.

💊 Treatment & Management

1. Medical Therapy

• Long-course, culture-driven antibiotics: enrofloxacin, trimethoprim-sulfa, penicillin used.
• Anti-inflammatories: NSAIDs, judicious use of steroids if inflammation is severe.
• Topical treatments: nasal saline flush, nebulization with gentamicin or saline.

2. Dental Management

• Correct molar or incisor malocclusion under anesthesia.
• Tear duct flush if tear flow is blocked due to dental root compression.

3. Surgical Options

• Sinus trephination to drain abscesses or pus collections.
• Endoscopic debridement in specialty settings.

4. Supportive Care

• Steam or pediatric nebulizer sessions can soothe nasal passages.
• Humidified air, clean environment, quality hay, and balanced diet.
• Eye and nasal hygiene carried out daily by owner.

📊 Prognosis & Follow‑Up

• Acute cases often respond well with appropriate therapy.
• Chronic or recurrent “snuffles” require aggressive treatment and long-term follow-up.
• Dental causes should always be addressed to prevent relapse.
• Regular monitoring—recheck imaging, cultures, and dental exams—reduces recurrence.

🏠 Home Care & Owner Support

• Daily cleaning of nasal crusts and eyes using warm saline wipes.
• Maintain clean, low-dust environment and ventilated enclosure.
• Encourage hydration and easy feeding—include hay, fresh greens.
• Owner-led nebulization if prescribed; ensure compliance.
• Weight, breathing, and nasal discharge logs help monitor recovery.

🧠 Vet Tips for 2025

• Think CT early—detect root causes hidden on plain x-rays.
• Culture before antibiotics—target therapy for best outcomes.
• Work as a team: integrate medicine, dental care, environment, and owner education.
• Train owners on inhalation and hygiene protocols to reduce stress and improve compliance.

🔚 Final Takeaway

Rhinitis and sinusitis (“snuffles”) are common and potentially serious in rabbits. In 2025, advanced diagnostics like CT and endoscopy, combined with targeted antibiotics, dental corrections, and owner-delivered care (e.g. nebulization and cleaning), offer the best path to resolution. Long-term management and prevention ensure healthy breathing and quality of life for your bunny. 🐇❤️
