If your Maltese is breathing heavily at night, you might notice rapid panting, loud snoring, or a fluttering sound. This is often a sign of an underlying issue that needs attention. Common causes in this breed include reverse sneezing, anxiety, brachycephalic airway syndrome (even though Maltese are not extreme brachycephalics), collapsing trachea, or heart disease. Start by observing if your dog is awake or asleep when heavy breathing occurs, and check for other symptoms like coughing or restlessness. Always consult a licensed veterinarian for a proper diagnosis.
Reverse Sneezing and Nasal Irritation
Maltese dogs are prone to reverse sneezing, which sounds like a honking or snorting, often at night. This happens when the soft palate irritates the throat, causing a spasm. Triggers include excitement, dust, or lying on their back. To help, gently massage your dog’s throat or cover its nostrils briefly to encourage swallowing. If episodes become frequent, a vet can check for allergies or elongated soft palate.
Anxiety and Stress
Maltese are sensitive and may experience separation anxiety or fear of darkness, leading to heavy breathing. Signs include pacing, whining, and seeking comfort. Create a calm bedtime routine: a cozy bed, quiet environment, and maybe a white noise machine. For severe anxiety, vet-recommended calming aids or behavior training can help. Do not give any medication without veterinary advice.
Brachycephalic Airway Syndrome and Sleep Apnea
While Maltese are not as flat-faced as Pugs, many have slightly shortened airways due to their small size. This can cause sleep apnea, where breathing stops briefly during sleep, then resumes with a loud gasp. Overweight dogs are at higher risk. Keep your Maltese at a healthy weight and avoid tight collars. If you suspect sleep apnea, a vet may recommend a sleep study or surgery for narrowed nostrils.
Collapsing Trachea and Heart Issues
Maltese are predisposed to collapsing trachea, a condition where the windpipe flattens, especially when excited or lying down. Symptoms include a goose-honk cough and heavy breathing. Heart disease, like mitral valve disease, can also cause nighttime breathing difficulty due to fluid buildup. If your dog has a cough, bluish gums, or tires easily, see a vet immediately. Treatment may include medication or lifestyle changes.
When to See a Vet
Consult your veterinarian if your Maltese has labored breathing (belly moving with each breath), bluish tongue, fainting, or coughing up foam. Also seek help if heavy breathing is sudden or paired with lethargy. Keep a record of when the breathing occurs and any triggers. At the vet visit, be ready to describe the sound (panting, honking, or rattling) and whether it happens during sleep or wakefulness.
Key Takeaway
Observe your Maltese’s breathing pattern and associated symptoms, then consult a veterinarian to identify the specific cause and get a tailored treatment plan.
