dog breathing heavy

Your dog normally breathes calmly, but hasn’t he ever been “shorter than usual”? Shortness of breath tends to occur in hot weather and after exercise, but if this is not the case, it may be a sign of illness.

Therefore, this time, I would like to introduce the causes of shortness of breath in dogs and the illnesses that can be considered when breathing out. If you are having trouble with your dog’s breathlessness, please refer to it.

What causes a dog to run out of breath?

There are three main causes of a dog’s breathlessness. First, I will explain each cause in detail.

Physiological phenomenon

This “physiological phenomenon of shortness of breath” is the most common cause of shortness of breath in dogs. Shortness of breath due to physiological phenomena occurs after exercise such as walking or playing, or when it is hot. When exercising, muscles consume a lot of oxygen, so they quickly supply oxygen from outside the body and thus breathe faster.

Also, dogs cannot sweat like humans. Therefore, when the body temperature becomes high, the body temperature is adjusted by opening the mouth and breathing. This is called punting

Panning, which occurs after exercise and when it’s hot, is a physiological phenomenon, so it’s okay if you rest and calm down quickly. However, if you’re not warm and you’re not wearing exercise and you’re panning, or if it’s significantly more intense than usual, you may be ill. If you experience any of these symptoms, seek medical attention at a hospital.


When you become obese, you quickly become tired because you use physical strength and muscles that you do not need to support a heavy body. Therefore, when climbing a small hill, climbing stairs, or running for a while, it is easy to run out of breath after a short movement. In addition, fat around the neck causes pressure on the respiratory tract and other respiratory tracts, which can cause shortness of breath.


You may become short of breath when your sympathetic nerve becomes dominant, such as when you are agitated or when you are scared, nervous, or anxious. Most of the time, your breathing will return to normal once the cause of your anxiety disappears.

  • Possible illnesses when a dog runs out of breath
If your dog’s breathlessness is stronger than usual, or if you are short of breath without exercise, you should seek medical advice from a veterinarian because you may be ill. Here are some possible illnesses when a dog runs out of breath.


It is a disease that causes inflammation of the bronchi of the air passage. It is caused by infection with viruses and parasites, chemicals in house dust and tobacco, and accidental ingestion. It is said that puppies and old dogs are more susceptible. If the cause is a virus, vaccination can be prevented and vaccination should be performed firmly.

Tracheal collapse

Tracheal collapse is a disease in which part of the trachea is deformed and collapses when breathing. Not only are you short of breath, but you often have dry coughing. The exact cause is unknown, but it is thought to be related to heredity, obesity, and aging.


Pneumonia is a condition in which inflammation reaches the lungs due to the exacerbation of respiratory diseases. It is caused by bacteria, fungi, parasites, as well as inhaled drugs and gases. See your veterinarian early because it can cause severe coughing, runny nose, dyspnea, and in the worst case, death.

Pulmonary edema

Pulmonary edema is a disease in which water accumulates in the lungs. Most pulmonary edema in dogs is caused by heart disease (such as mitral regurgitation) and pneumonia. With pulmonary edema, coughing and breathing become severe and shortness of breath becomes severe. If pulmonary edema progresses further, coughing and dyspnea worsen, and you often sleep with your mouth open and your forefeet tight, so if you sleep unnaturally and have short breaths, go to a hospital early. let’s go.

Mitral regurgitation

Mitral regurgitation is the most common heart disease in dogs, with a high incidence in older small dogs. It is a disease that occurs when the mitral valve, which is located between the left atrium and left ventricle of the heart, deforms for some reason, resulting in insufficiency.


In the early stages, there are no noticeable symptoms, but coughing and shortness of breath increase as you progress. In addition, as the disease progresses, the chance of causing pulmonary edema increases, and not only shortness of breath, but also respiratory distress is common.

This time, we introduced the causes of shortness of breath in dogs and the diseases that can be considered when shortness of breath.

As I introduced this time, the cause of shortness of breath in dogs may be not only physiological phenomena but also signs of illness. If you do not judge that you are “out of breath” and something is out of the ordinary, you should visit a veterinary clinic immediately.
