As dog owners, we all have our own beliefs and perceptions about dog behavior. Whether it’s their wagging tail or barking, we naturally assume these common behaviors are normal. The same goes for panting. But what happens when your dog pants excessively? Should you be concerned about their health? Panting in dogs can have various causes, some normal and others worrisome.

The frequency, timing, and accompanying symptoms of panting determine whether it’s a cause for concern. That’s why today we’ll explore the different reasons behind panting and when it might be necessary to take action or visit the veterinarian. Certain breeds and individual dogs may be more prone to panting than others, but most often, panting is an indicator that something is going on. So, let’s investigate why your dog is panting excessively and what you can do about it.

What Causes Panting In Dogs

The most common reason dogs pant is to regulate their body temperature. They do this by exchanging hot air from their lungs with cooler air from the environment, primarily through their tongue. This process facilitates evaporation and helps dissipate heat from their bodies. However, panting can also occur due to emotional changes, diseases, or injuries.


Heatstroke can be easily summarized as when a dog cannot cool themselves down. This may be because of their thick coat, too hot of an environment, or no access to anything to cool them. It is important to note that this is a fatal condition for any dog. Within ten to twenty minutes this condition can kill a dog. This is why advocating for not leaving your dog in a hot car is so crucial, it really is that dangerous. So be aware of the hot temperatures in Summer.

Panting is a sign that your dog may be overheating, but this does not necessarily mean they are suffering from heatstroke. Other signs of heatstroke include vomiting, shifting, lethargy, and even unresponsive behavior. Furthermore, the panting displayed in this case is often heavy and rapid as a desperate attempt to rid themself of heat. As dogs cannot sweat as much as we can, this is the main technique of heat release.

Dogs with thicker coats, obese, or short-snouted, also known as brachycephalic dogs, are much more at risk of heatstroke than other dogs. Any signs of heatstroke and your dog will need an immediate vet visit and treatment to try to help. Panting does not mean your dog has heatstroke, but always monitor their accompanying behavior to see if this is a worry.

Pain and Stress

Both pain, stress, and other quick emotional changes like anxiety or excitement can lead to your dog panting. They all share the common cause of an increase of adrenaline and cortisol which leads to this behavior. This is through an internal rise in body temperature and also an increased demand for oxygen. These causes lead to your dog panting regardless of the temperature outside. If your dog is panting because of excitement for a walk then this is not a concern. However, if they are anxious either generally or because of a change of situation, this will require some support to make them feel better. Cushing’s disease is also a cause for panting due to an increase in the hormone cortisol being produced. This will require a vet visit and treatment.

Pain is another cause for a dog panting a lot. Beyond the release of adrenaline and cortisol from an injury or general pain, there are also other symptoms which can lead to panting. Discomfort and pain can cause your dog to feel stressed or anxious which may increase the behavior. Furthermore, they may feel nausea and therefore have a higher frequency of drool and panting due to feeling like they may vomit.

Heart Failure

The purpose of a dog’s heart is to pump oxygen all around the body through the blood. When your dog’s heart begins to fail, then your dog will struggle to receive the necessary amount of oxygen they need. This is why heart failure can cause panting. By increasing a dog’s breathing to the level of rapid panting, they are taking in more air to try to gain a higher level of oxygen. Therefore, they will hopefully be able to satisfy their required need for oxygen and get it passed around the body.

You can identify heart failure from more than panting though. Be aware of lethargy as the main symptom. Will your dog being able to take in less oxygen, they will feel weaker and less able to participate in exercise. Therefore, they may be lying down more, sleeping more, and playing less. Walks and toys may also be of less interest to them because they struggle to participate. Furthermore, your dog may also be coughing. This is because of fluid entering the lungs because of the heart’s inability to function properly. The heart has to work harder to perform its normal job, and therefore the pressure to move blood around the body increases. This pressure is what leads to liquid being pushed into the lungs which causes your dog’s cough.

Respiratory Illnesses

There are multiple diseases that can affect the respiratory system. Any one of these diseases can lead to an increase in your dog’s panting. Some that are more common or more likely to produce symptoms include tumors, pneumonia, or kennel cough. All respiratory infections lead to your dog struggling to breathe. Whether because of a blockage, inflammation, or fluid build-up. These all lead to a dog struggling to breathe properly and therefore they will do so more frequently or with more conviction. Therefore this is why they pant.

Other symptoms that may accompany the painting include coughing, lethargy, and gagging. Coughing can occur due to fluid build-up and irritation, as your dog’s body is trying to dislodge that unpleasant feeling. This is the same for liquid build-up in the lungs. Dogs will cough to try to remove it to allow better breathing. Gagging exists for the same purpose.

What Should You Do For a Panting Dog

When it comes to your dog’s panting, it’s always a good idea to consult a veterinarian, especially in the case of heatstroke. Excessive panting in dogs can indicate various issues, ranging from minor concerns like anxiety to more severe conditions such as heart failure. By seeking professional help, vets can conduct tests to determine the cause of the panting and provide appropriate treatment or recommendations. If anxiety is the cause, you can then investigate the underlying factors and make changes to help your dog.

Here are some important tips to keep your dog cool, which can help prevent heatstroke, general panting, discomfort, and stress. Always ensure your dog has access to cool water, especially if they tend to drool a lot. Providing shaded areas, air conditioning, or cooling mats can also help your dog stay comfortable in hot weather. Additionally, keeping your dog’s coat well-groomed and trimmed can prevent constant discomfort and ensure their safety.
