It’s normal to see your dog panting, especially after a playful session in the park or on a warm day. Panting is a natural cooling mechanism for dogs, but when does panting become excessive and a cause for concern? Understanding your dog’s normal breathing patterns and recognizing the signs of abnormal panting is crucial for their health and well-being.
On average, a healthy dog at rest takes between 15 to 35 breaths per minute. Anything consistently above 40 breaths per minute when your dog is resting is considered abnormal and warrants attention. While panting is often harmless, it can also signal underlying health issues that require veterinary care. Let’s delve into why dogs pant and when excessive panting should raise a red flag.
Normal Panting: How Dogs Cool Down
Dogs pant because they don’t sweat like humans do. Their primary way to regulate body temperature is through panting. This process allows them to dissipate heat and evaporate water from their tongue, mouth, and upper respiratory tract.
The Science Behind Panting: Evaporative Cooling
Panting is a clever biological trick that utilizes the principle of evaporative cooling. Here’s how it works:
- Heat Absorption: Heat from your dog’s body warms the saliva on their tongue and the moist tissues in their mouth and respiratory system.
- Evaporation: As your dog pants, air moves rapidly over these moist surfaces. This airflow causes the water (saliva) to evaporate.
- Heat Release: The process of evaporation requires energy, which it draws from the dog’s body heat. As the saliva evaporates, it takes heat away, effectively cooling your dog.
- Cool Air Intake: With each pant, your dog inhales cooler air, further aiding in lowering their internal temperature.

Just like sweating in humans, panting is a normal and essential physiological response to heat, exercise, and even excitement. However, it’s important to differentiate between normal and excessive panting.
When Panting Becomes Excessive: Recognizing Abnormal Panting
Knowing what’s normal for your dog is the first step in identifying abnormal panting. To determine if your dog is panting excessively, observe them when they are resting or sleeping.
How to Check Your Dog’s Breathing Rate
- Quiet Observation: When your dog is calm and relaxed, gently observe their chest rising and falling.
- Count Breaths: Count the number of breaths they take in a minute. One breath includes both an inhale and an exhale.
- Establish a Baseline: It’s a good idea to determine your dog’s normal resting respiratory rate when they are healthy, so you have a baseline for comparison.
If your dog’s breathing rate exceeds 35-40 breaths per minute at rest, or if their panting seems unusually heavy or labored, it could be a sign of a problem.
Causes of Excessive Panting in Dogs: What Could Be Wrong?
While heat and exercise are common triggers for panting, excessive panting, especially when your dog is at rest, can indicate various underlying issues.
Common and Serious Causes of Excessive Panting
- Heat and Exercise: This is the most common and normal reason for panting. After physical activity or in warm environments, dogs pant to cool down.
- Breed Predisposition: Brachycephalic breeds, like Pugs, Bulldogs, and Boxers, are more prone to breathing difficulties due to their short snouts and compressed airways. They may pant more easily and are at higher risk of overheating.
- Underlying Medical Conditions: Excessive panting can be a symptom of various health problems, including:
- Respiratory Issues: Asthma, kennel cough, pneumonia, lung diseases (including cancer), fungal or bacterial infections, collapsing trachea, and laryngeal paralysis can all cause increased panting.
- Cardiovascular Problems: Heart disease can lead to fluid buildup in the lungs, causing shortness of breath and panting.
- Pain and Discomfort: Pain from injuries, arthritis, or other conditions can trigger panting.
- Anxiety and Stress: Stressful situations, anxiety, or phobias can lead to rapid panting.
- Medications: Some medications can have panting as a side effect.
- Heatstroke: This is a severe and life-threatening condition where the dog’s body overheats dangerously. Excessive panting is a key symptom.
- Anemia: A low red blood cell count can lead to panting as the body tries to get more oxygen.
- Bloat (Gastric Dilatation-Volvulus): A life-threatening condition, especially in large breed dogs, where the stomach fills with gas and can twist. Panting is a symptom.

This is not an exhaustive list, and it’s essential to consult with your veterinarian to determine the exact cause of your dog’s excessive panting.
When to Be Seriously Concerned: Emergency Signs
It’s crucial to recognize when your dog’s panting is not normal and requires immediate veterinary attention. Seek emergency veterinary care if you observe any of the following signs along with excessive panting:
Red Flags of Abnormal Panting:
- Sudden Onset Panting: Panting that starts abruptly and for no apparent reason.
- Panting at Rest: Open-mouthed breathing and heavy panting when your dog is resting or inactive.
- Labored Breathing: Noticeable effort when breathing, including exaggerated chest or abdominal movements.
- Noisy Breathing: Panting that sounds louder or different from their usual panting.
- Changes in Gum Color: Pale, blue-tinged, or brick-red gums, which can indicate oxygen deprivation or other serious issues.
- Lethargy and Weakness: Reluctance to move, eat, or drink, along with panting.
- Excessive Drooling: Drooling more than usual, especially if it’s thick or stringy.
If your dog exhibits any of these signs alongside excessive panting, don’t delay – contact your veterinarian immediately or go to the nearest emergency animal hospital.
Diagnosing the Cause of Excessive Panting
To determine why your dog is panting excessively, your veterinarian will conduct a thorough physical examination. They will assess your dog’s:
Veterinary Examination and Diagnostic Steps:
- Physical Exam: Checking vital signs, listening to the heart and lungs, and palpating the abdomen.
- Medical History: Gathering information about your dog’s past health issues, medications, and recent activities.
- Diagnostic Tests: Depending on the initial assessment, your vet may recommend:
- Blood Tests: To check for anemia, infection, and organ function.
- Urinalysis: To evaluate kidney function and detect urinary tract infections.
- Radiographs (X-rays): To visualize the heart, lungs, and abdomen for abnormalities like tumors, fluid buildup, or enlarged organs.
- Electrocardiogram (ECG): To assess heart rhythm and electrical activity.
- Ultrasound: To examine internal organs in more detail.
- Other Specific Tests: Based on suspected conditions.
By combining the physical exam findings and diagnostic test results, your veterinarian can pinpoint the underlying cause of your dog’s excessive panting and recommend the appropriate treatment.
Treatment for Excessive Panting
Treatment for excessive panting is directed at addressing the underlying cause. It will vary greatly depending on the diagnosis.
Potential Treatments:
- Addressing Underlying Conditions: Treatment will focus on managing or resolving the diagnosed medical issue, such as medications for heart or lung disease, antibiotics for infections, or pain management.
- Oxygen Therapy: In cases of respiratory distress, oxygen therapy may be necessary to stabilize your dog.
- Rest and Supportive Care: Rest, a cool environment, and supportive care are often crucial for recovery.
- Behavioral Therapy: If anxiety or stress is the cause, a certified dog behaviorist may be recommended for training and behavior modification techniques.
- Hospitalization: In severe cases, hospitalization may be required for continuous monitoring, oxygen support, and intensive treatment.
Always follow your veterinarian’s recommendations closely and ensure your dog receives the prescribed treatment to address their excessive panting and any underlying health concerns.
Conclusion: When in Doubt, Consult Your Vet
While panting is a normal bodily function for dogs, excessive panting can be a sign of an underlying medical problem. By understanding the difference between normal and abnormal panting and being aware of the warning signs, you can take proactive steps to protect your furry friend’s health. If you are ever concerned about your dog’s panting, don’t hesitate to contact your veterinarian. Early diagnosis and treatment can make a significant difference in your dog’s well-being.
If you are concerned about your dog’s excessive panting, please contact your veterinarian for an examination and professional advice.
