Panting and wheezing in dogs can be alarming. While panting is a normal way for dogs to regulate temperature, wheezing often signals difficulty in breathing and may indicate a health issue.
We outline the common causes of panting and wheezing in dogs, what you can do at home, and when to seek veterinary help.
Dog Panting and Wheezing — Why It Happens
When a dog is panting and wheezing, it often indicates a respiratory problem that makes it difficult for them to breathe normally. Wheezing occurs when airways are narrowed or obstructed due to issues like allergies, asthma, bronchitis, collapsing trachea, or heart disease.
The panting is the dog’s way of trying to get more oxygen to compensate for reduced airflow. In some cases, infections or inhaled irritants like smoke or dust can also trigger both symptoms.
Because breathing difficulties can quickly become life-threatening, any combination of panting and wheezing warrants prompt veterinary evaluation.
Dog Panting and Wheezing: Common Causes
Respiratory Infections
Respiratory infections are a frequent cause of panting and wheezing in dogs. Conditions such as kennel cough, pneumonia, or upper respiratory tract infections can inflame the airways, making breathing labored and noisy.
Signs to watch for include coughing, nasal discharge, lethargy, and a decrease in appetite.
Early veterinary care can help prevent complications, especially in young, elderly, or immunocompromised dogs.

Allergies
Allergic reactions can trigger both panting and wheezing. Dogs may react to environmental allergens such as pollen, dust mites, mold, or certain foods.
The immune response can cause airway inflammation, leading to wheezing, while panting may occur as the dog struggles to maintain oxygen levels.
You may notice scratching, watery eyes, sneezing, or skin irritation. Identifying and minimizing exposure to allergens, along with veterinary guidance, can greatly improve your dog’s comfort.
Heart Disease
Heart conditions, such as congestive heart failure, can result in panting and wheezing. When the heart cannot efficiently pump blood, fluid may accumulate in the lungs, leading to labored breathing.
Symptoms may also include coughing, exercise intolerance, pale or bluish gums, and restlessness at night. Prompt veterinary evaluation is essential for diagnosis and treatment to prevent serious complications.
Obstruction in the Airways
Physical obstructions, such as a foreign object lodged in the throat or nasal passages, can cause panting and wheezing. Dogs may inhale or swallow small objects that partially block airflow, resulting in noisy breathing and rapid panting.
You may observe gagging, coughing, pawing at the mouth, or sudden distress. Immediate veterinary intervention is critical to remove the obstruction and restore safe breathing.
Collapsed Trachea
Tracheal collapse is a common problem in small breed dogs, leading to panting and wheezing. The weakening of the tracheal rings causes partial airway collapse, especially during exertion or excitement.
Signs include a honking cough, labored breathing, and sometimes cyanosis (bluish gums). Veterinary management may include medications, weight control, and lifestyle adjustments to reduce strain on the airway.
Heatstroke or Overheating
Excessive panting and wheezing can result from overheating or heatstroke. Dogs exposed to high temperatures, especially brachycephalic breeds, may struggle to cool themselves efficiently.
Other indicators include drooling, lethargy, vomiting, or collapse. Immediate action, such as moving your dog to a cool area and offering water, is vital while seeking veterinary care if symptoms are severe.
What to Do If Your Dog Is Panting and Wheezing
Ensure your dog has access to a cool, well-ventilated area and fresh water to reduce overheating.
Observe your dog’s breathing pattern and overall behavior to distinguish between mild stress, excitement, or potential medical issues.
Minimize exposure to allergens and environmental triggers that may worsen respiratory symptoms.
Provide gentle reassurance and avoid overexertion or stressful situations while monitoring for changes.
Contact your veterinarian if panting and wheezing persist, worsen, or are accompanied by other concerning signs like lethargy, coughing, or pale gums.
When to Call or Visit Your Vet
Seek immediate veterinary care if your dog shows:
Severe, continuous panting with wheezing or labored breathing
Blue or pale gums indicating oxygen deprivation
Collapse, extreme weakness, or fainting
Persistent coughing or gagging
Vomiting or signs of distress along with breathing difficulty
Prompt evaluation is crucial for identifying serious conditions and starting timely treatment.

Key Takeaway
Panting and wheezing in dogs can range from mild issues, like excitement or allergies, to serious health problems such as heart disease or airway obstruction.
Observing your dog’s behavior, maintaining a safe environment, and seeking veterinary care when necessary can help differentiate normal panting from potentially dangerous conditions.
Timely attention and supportive care ensure your dog stays comfortable, safe, and healthy.
