Loud breathing That SoundS Like "Flu"

Loud breathing in rabbits — especially when it sounds like a “flu” — is often a sign of respiratory distress and should be taken seriously. Rabbits are prone to respiratory infections and other conditions that can quickly become dangerous if untreated.

Common Causes of Loud Breathing in Rabbits

• Respiratory infections (“snuffles”): Often caused by bacteria such as Pasteurella multocida. Symptoms include nasal discharge, sneezing, and noisy breathing.

• Allergies or irritants: Dusty hay, smoke, or strong scents can irritate the airways.

• Dental problems: Overgrown teeth or abscesses can press on nasal passages, leading to noisy breathing.

• Pneumonia or serious lung issues: More severe infections can cause labored breathing, lethargy, and loss of appetite.

• Obstructions: Foreign material or swelling in the nasal passages may block airflow.

Warning Signs That Require Immediate Vet Attention

• Persistent loud breathing or wheezing

• Nasal discharge (clear, white, or yellow)

• Sneezing or coughing

• Loss of appetite or reduced drinking

• Lethargy or unusual posture (sitting hunched, difficulty moving)

What You Can Do Right Away

• Check the environment: Remove dust, smoke, or strong odors.

• Monitor closely: Note changes in appetite, activity, or discharge.

• Do not delay veterinary care: Rabbits hide illness well, and respiratory problems can worsen quickly.

Bottom line

Loud, flu‑like breathing in rabbits is not normal and often signals infection or another health issue. Because rabbits can deteriorate rapidly, the safest step is to have your rabbit examined by a veterinarian as soon as possible.
