Understanding normal puppy breathing patterns
How fast is normal?
Puppies generally breathe faster than adult dogs due to their higher metabolic rate and developing respiratory system. A normal respiratory rate for a puppy at rest ranges between 15 and 40 breaths per minute, while adult dogs typically breathe a bit more slowly.
Factors that can influence a puppy’s breathing rate include:
- Age and developmental stage
- Physical activity level
- Sleep stage (e.g., REM sleep)
Common reasons for fast breathing in puppies
Puppies breathe faster than adults for a few reasons, including:
- Dreaming and REM sleep: Puppies often experience rapid breathing while dreaming during REM sleep, which is sometimes accompanied by twitching or whimpering.
- Excitement or play: Increased breathing after play is a normal response to heightened activity and emotions.
- Cooling down: Dogs regulate their body temperature primarily through panting, which can cause an increased breathing rate after exertion.
Medical reasons why puppies may breathe fast
Respiratory illnesses
Some health conditions can cause abnormal breathing patterns in puppies. Common respiratory illnesses include:
- Kennel cough: A contagious upper respiratory infection that may cause coughing, sneezing, and rapid breathing
- Pneumonia: A lung infection with symptoms that may include labored breathing, lethargy, and nasal discharge
Heart conditions
Congenital heart defects can affect some puppies, leading to symptoms that may include:
- Fatigue and weakness
- Persistent coughing
- Pale or bluish gums
Genetic causes
Puppies from certain breed groups may have more trouble breathing than others.
“Certain dogs, including brachycephalic breeds like French Bulldogs, Boxers, and Pugs, are prone to breathing difficulties and may be at a higher risk for heavy panting than other dogs,” Dr. Ricky Walther, DVM, notes. “Owners of these breeds should closely monitor their dogs for signs of increased respiratory effort, such as wheezing or struggling to breathe.”
Other serious causes
Other health conditions affecting puppies can cause rapid breathing, including:
- Heatstroke: Overheating can result in excessive panting and difficulty breathing.
- According to Dr. Ricky, most pet parents are unaware of how quickly heatstroke-–a potentially fatal condition with a mortality rate of about 50 percent—can occur.
- Allergic reactions: Exposure to allergens may lead to respiratory distress.
- Infections: Some non-respiratory bacterial or viral infections can trigger abnormal breathing rates.
When should you worry about fast breathing?
Red flags to watch for
While occasional fast breathing can be normal for a puppy, the following red flags can indicate a serious problem:
- Labored breathing (i.e., deep chest movements, nostril flaring, or struggling to inhale)
- Blue or pale gums, which indicate oxygen deprivation
- Unresponsiveness or extreme lethargy
When to contact your vet
Seek veterinary care immediately if you notice any of the above red flag symptoms. Additional reasons to contact your vet include:
- If your puppy’s breathing rate exceeds 40 breaths per minute at rest
- If rapid breathing is accompanied by other concerning symptoms (e.g., coughing, wheezing)
- If you are uncertain whether your puppy’s breathing pattern is normal
Steps to take if your puppy is breathing fast
At-home monitoring
Watch your puppy closely if you notice fast breathing. Specifically, you should:
- Count and record your puppy’s breaths per minute when they are at rest
- Observe their behavior to determine if they seem distressed or uncomfortable
Immediate actions for emergencies
If you think your puppy’s breathing problem is an emergency, take these steps:
- Keep your puppy calm to prevent further distress.
- Move your puppy to a cool, well-ventilated environment if overheating is a concern.
- Take your puppy to the vet or the nearest emergency facility if symptoms persist.

Frequently asked questions about fast breathing in puppies
Why does my puppy breathe fast when sleeping?
Puppies experience REM sleep with high brain activity, causing rapid breathing, twitching, and movement.
Can teething cause fast breathing in puppies?
While teething can cause discomfort, it does not directly cause an increased breathing rate. However, stress and pain may contribute to shallow or fast breathing.
What if my puppy breathes fast after eating?
Mildly increased post-meal breathing is normal, but excessive panting or signs of distress could indicate bloating or other gastrointestinal issues requiring veterinary attention.
If you’re ever in doubt about your puppy’s breathing, consult your veterinarian for expert guidance.
