Why Is My Dog Breathing Fast? Understanding Causes and When to Worry

Your dog hasn’t been exercising or playing, but for some reason, they are breathing fast. Should you be worried? While occasional fast breathing may not always be a sign of trouble, it’s essential to know when it could indicate a more serious issue. 

Below, you’ll find common reasons why your dog might be breathing fast, how to tell if it’s abnormal, and when you should call the vet.

What Is a Normal Breathing Rate in a Dog?

A dog’s normal respiratory rate at rest ranges between 15 and 35 breaths per minute. If your dog is breathing faster than 40 breaths per minute while at rest, this is considered abnormal and may indicate a problem.

How to Measure Your Dog’s Breathing Rate

To determine if your dog’s breathing is within a healthy range, follow these steps:

1. Ensure your dog is at rest and calm.
   

2. Watch or place your hand gently on their side.
   

3. Use your phone's timer to time yourself while you count the number of breaths they take in 30 seconds, then double that number to obtain the breaths per minute (one inhale + one exhale = one breath).
   

4. If your dog’s fast breathing persists or exceeds 35–40 breaths per minute, monitor for other symptoms and consult your vet.

Should I Be Worried if My Dog Is Breathing Fast?

Fast breathing in dogs isn’t always an emergency, but it can indicate an underlying health issue. If your dog’s breathing is noticeably labored, involves engaging stomach muscles, or is accompanied by signs of respiratory distress (such as open-mouthed breathing while at rest), you should seek veterinary advice.

What Is the Difference Between Fast Breathing and Normal Panting?

Panting is a natural cooling mechanism for dogs, helping them regulate their body temperature when they are warm or have been active. Since dogs don’t sweat like humans, they rely on rapid breathing to circulate air through their bodies, allowing heat and moisture to evaporate from their tongue, mouth, and upper respiratory tract. For example, your dog may pant to cool down after a brisk walk or play session. This is completely normal. Occasional open-mouth breathing after exercise is normal and helps them return to a comfortable temperature.

Fast breathing, on the other hand, can occur even when your dog is resting and may appear abnormal, with increased respiratory effort and involvement of the lungs, airway, neck, or head. If your dog is lying down, appearing lethargic, and breathing heavily with no apparent cause, this may indicate an issue that requires veterinary attention.

How to Calm a Dog’s Breathing

If your dog is breathing fast due to stress or anxiety, try these techniques to help them relax:

• Create a calm environment – Remove triggers like loud noises or excessive activity.
  

• Use an Anxiety Calming Dog Earmuff Protector – This can help reduce stress during storms or in loud environments.
  

• Offer water and shade – Ensure your dog stays hydrated and cool.
  

• Check for signs of pain or discomfort – If your dog is acting normally otherwise, it may just be temporary anxiety. However, persistent breathing difficulties warrant a vet visit.

Why Is My Dog Breathing Fast?

There are several reasons why a dog may be breathing fast, including:

1. Overheating or Heat Stroke – Excessive panting or rapid breathing can occur if your dog struggles to cool down.
   

2. Pain or Injury – Dogs may breathe abnormally fast if they have broken ribs, muscle strain, or internal injuries.

3. Respiratory Conditions – Upper respiratory tract infections, asthma, lung diseases, pneumonia, and lung tumors can all cause difficulty breathing.
   

4. Heart Disease – A weakened circulatory system can lead to increased respiratory effort as the body struggles to get oxygen.
   

5. Anxiety or Stress – Other psychological factors, such as fear, can lead to rapid breathing.
   

6. Anemia or Blood Disorders – If your dog has a low red blood cell count, their circulatory system may struggle to supply oxygen, leading to heavy breathing in dogs.
   

7. Obstruction in the Airway – A blockage in the lungs, airway, or neck, such as a swallowed object, can cause labored breathing.
   

8. Medical Conditions Affecting the Chest or Abdomen – Conditions like fluid buildup in the lungs due to pneumonia or an enlarged abdomen from bloating can put pressure on the lungs, making breathing difficult.

If My Dog Is Breathing Fast, What Other Symptoms Should I Watch For?

Fast breathing alone may not always be a cause for concern, but if you notice any of the following symptoms, consult a vet immediately:

• Noticeably labored breathing or excessive use of the stomach muscles

• Coughing or wheezing

• Pale or blue gums (indicating low oxygen levels)

• Lethargy or weakness

• Collapsing or fainting

• Refusing to eat or drink

• Open-mouthed breathing while at rest

When to Contact the Vet

If your dog is experiencing respiratory distress, fast breathing for an extended period, or any other abnormal breathing symptoms, it’s time to contact your vet. The vet will perform an accurate diagnosis and may use tools like X-rays, blood tests, or oxygen therapy to assess your pet’s condition.

Treatment Options for Fast Breathing in Dogs

Depending on the underlying cause, treatment options may include:

• Oxygen therapy – To support breathing in dogs experiencing severe respiratory distress.
  

• Intravenous fluids – To help stabilize dogs suffering from dehydration or other underlying conditions.
  

• Pain relief and medication – If the vet diagnoses pain or inflammation, they may prescribe pain relief to ease discomfort.
  

• Treatment for infections or lung diseases – Antibiotics or other medications may be used to address respiratory infections.
  

• Management of heart disease or other conditions – Some dogs may require long-term treatment for chronic conditions affecting their circulatory system, lungs, airway, and neck.
