Common reasons your puppy might be breathing fast during sleep:
- Dreaming During REM Sleep
- Recent Exercise
- Overheating
- Anxiety
- Dehydration
- Injury or Pain
- Respiratory Infection
- Heart Problems
- Anemia
- Diaphragmatic Hernia
Puppies frequently breathe faster while sleeping, and in most cases, it’s completely normal. As long as their breathing stabilizes and there are no other unusual symptoms, your pup is likely just fine.
Rapid breathing during sleep typically lasts anywhere from a few minutes to 10 minutes.
If your puppy’s breathing seems unusually fast or continues for an extended period, you can gently wake them to see if their breathing returns to normal. That said, avoid doing this too often, as your puppy might not appreciate the interruption!

Dreaming During REM Sleep
Just like humans, dogs experience REM (Rapid Eye Movement) sleep, a stage where dreaming occurs. During this phase, puppies may imagine exciting, stressful, or even scary scenarios.
While dreaming, their sympathetic nervous system responds as if the events are real, triggering the release of adrenaline-like chemicals such as epinephrine and norepinephrine. These chemicals prepare the body for action, causing an increase in heart rate, blood pressure, and breathing rate.
Puppies also expend significant energy during REM sleep, leading to faster breathing to meet their oxygen demands. Both puppies and adult dogs often experience rapid breathing as they transition through dream cycles, which can last a few minutes and happen multiple times during sleep.
In addition to fast breathing, you might observe other dream-related behaviors, such as:
- Whimpering or barking
- Leg kicking or “running” motions
- Tense muscles
- Flickering eyelids
These actions are completely normal and indicate your puppy is engaging in a vivid dream, whether they’re chasing a toy or exploring a new world in their sleep.
They’re Overheated
Unlike humans, dogs can’t rely on sweating to cool down. Instead, they regulate their body temperature through evaporation from their tongues, mouths, and respiratory passages. Puppies, in particular, are less effective at controlling their body temperature, making them more susceptible to overheating.
To keep your puppy safe in warm weather, limit outdoor activities to the coolest times of the day, such as early morning or evening.
If your puppy is panting or breathing quickly at night, you can help them cool down by:
- Removing extra blankets from their sleeping area
- Adjusting the temperature by lowering the heat or using air conditioning
- Using a fan to circulate air
- Keeping their crate or bed away from direct sunlight
- Providing bedding with a cooler side so they can move to a comfortable spot
Signs of overheating to watch for include:
- Dehydration
- Excessive drooling
- Elevated body temperature
- Vomiting
- Red gums
If you observe any of these symptoms alongside rapid breathing, contact your veterinarian immediately to ensure your puppy’s safety.
They’re Feeling Anxious
Puppies are constantly exploring a new and exciting world filled with unfamiliar experiences, environments, and routines. This period of growth and adjustment can naturally cause moments of fear or anxiety as they adapt to new surroundings.
It’s not uncommon for puppies to feel uncertain when encountering new people, places, or situations. To help reduce anxiety, consider these strategies:
- Allow them to approach unfamiliar experiences at their own pace without pressure.
- Offer positive reinforcement and comforting reassurance to build confidence.
- Maintain a consistent daily routine to create a sense of stability.
- Provide a safe, quiet space, like a crate or bed, where they can relax and decompress.
Rapid breathing due to anxiety should subside once your puppy calms down and should not persist during sleep. If you notice ongoing stress-related behaviors, such as yawning, pacing, or shivering, consider moving their bed to a quieter area where they feel more secure.
Establishing a calm, predictable environment can make a significant difference in helping your puppy feel at ease and navigate their early stages of life with confidence.
They’re Dehydrated
Puppies require adequate water to stay hydrated—about an ounce of water per pound of body weight daily. Dehydration can occur quickly, especially in active or warm environments. Symptoms of dehydration include:
- Excessive panting
- Dry nose, eyes, or gums
- Loss of skin elasticity
- Dry mucous membranes
- Sunken eyes
To rehydrate your puppy, ensure they have access to fresh water or offer ice cubes as an alternative. If your puppy shows multiple signs of dehydration and refuses to drink, contact your veterinarian immediately for guidance and treatment.
They’re Injured or in Pain
Puppies’ natural curiosity and energy make them prone to injuries as they explore their environment. If your puppy is in pain, you might notice these signs:
- Stiff movements or altered posture
- Behavioral changes like lethargy, hiding, or whining
- Shaking or trembling
- Squinting or sensitivity to light
- Enlarged pupils
If your puppy exhibits these symptoms for more than a day or two, it’s essential to consult a veterinarian. Prompt diagnosis and treatment of the underlying cause can help alleviate discomfort and ensure your puppy stays healthy and happy.
They Have a Respiratory Infection
Puppies are particularly susceptible to respiratory infections because their immune systems are still developing. Conditions like kennel cough or pneumonia can pose serious health risks. In addition to rapid breathing—whether awake or asleep—you might notice the following symptoms:
- Nasal discharge (clear fluid, mucus, pus, or even blood)
- Persistent coughing, either dry or wet
- Shallow or labored breathing
- Wheezing sounds
- Difficulty catching their breath
To aid in recovery, ensure your puppy remains hydrated by offering plenty of water. Adding humidity to the air with a humidifier can also ease breathing. If you suspect a respiratory infection, it’s essential to consult your veterinarian for a proper diagnosis and timely treatment to prevent complications.
They Have a Heart Problem
Heart problems, although uncommon in puppies, can occasionally occur, particularly due to congenital heart defects inherited from their parents. Symptoms of heart conditions in puppies may include:
- Shortness of breath or difficulty breathing
- Persistent coughing
- Lethargy and low energy levels
- Fainting or collapsing episodes
- Fluid accumulation in the lungs or abdomen
If you suspect a heart issue, your veterinarian can perform diagnostic tests and recommend appropriate treatments. These may range from medications to manage symptoms to surgical interventions, depending on the severity of the condition. Proper treatment can significantly improve your puppy’s quality of life.
They Have Low Red Blood Cell Count (Anemia)
Anemia in puppies can arise from various causes, including exposure to toxins, injuries, infections, or underlying medical conditions. The impact of anemia depends on its cause and severity. Symptoms often include:
- Visible blood loss
- Low blood pressure
- Weight loss
- Lethargy or overall weakness
- Pale or pinkish gums
If you notice these signs, it’s crucial to seek veterinary care. A veterinarian may conduct diagnostic tests such as a complete blood count (CBC), blood and urine analyses, or X-rays to identify the root cause and develop a tailored treatment plan to support your puppy’s health.
They Have a Diaphragmatic Hernia
The diaphragm, a crucial muscle that facilitates breathing, can develop a hernia due to trauma or genetic factors. This condition can disrupt your puppy’s ability to breathe properly. Common symptoms of a diaphragmatic hernia include:
- Persistent coughing
- Loss of appetite
- Low energy or fatigue
- Breathing difficulties
- Fever
- Collapse
A veterinarian can diagnose a diaphragmatic hernia through a physical exam and imaging tests, such as X-rays. Based on the severity of the hernia, your vet may recommend surgery or other treatments to restore normal breathing and improve your puppy’s overall well-being.
Is My Puppy Breathing Fast or Panting?
To differentiate between fast breathing and panting in your puppy, check their mouth. If their mouth is open, they’re likely panting. If it’s closed, they’re breathing rapidly.
Panting during sleep is uncommon in puppies but can occur if they are overheated or feeling anxious. To keep your puppy comfortable, make sure they sleep in a cool, well-ventilated room and minimize stressors such as loud noises or unfamiliar visitors.
Occasional panting during sleep usually isn’t a cause for concern. However, excessive or prolonged panting, especially if accompanied by other signs of discomfort, may require veterinary attention.
What You Can Do:
- Observe your puppy’s panting pattern and how long it lasts.
- Look for any other unusual signs or behaviors.
- Share these observations with your veterinarian to help them determine if further evaluation or treatment is needed.
By keeping an eye on your puppy’s breathing and taking preventive measures, you can help ensure their health and comfort.
When Is Fast Breathing in Puppies an Emergency?
Fast breathing in puppies is usually harmless, but it can occasionally indicate a serious health problem. Certain symptoms accompanying rapid breathing should prompt immediate veterinary attention, including:
- Labored or strained breathing
- Excessive drooling
- Pale or discolored gums
- Signs of extreme distress or discomfort
If you notice any of these warning signs, it’s essential to contact your veterinarian immediately for evaluation and care. Early intervention can help address potential health issues and ensure your puppy’s well-being.
How to Keep Your Puppy Calm
To help soothe your puppy while waiting for veterinary care, create a comfortable, quiet environment. Ensure the temperature is moderate – not too hot or cold and provide a familiar blanket or toy for added comfort and security.
During the vet visit, your puppy will undergo a thorough examination to assess their overall health. Diagnostic tests may be conducted to identify the underlying issue, and your veterinarian will recommend the best treatment to support your puppy’s recovery.
How to Check Your Puppy’s Breathing Rate While They Sleep
Measuring your puppy’s breathing rate during a calm, deep sleep can help you determine what’s normal for them. Follow these steps:
- Observe Their Breathing: Watch your puppy’s chest rise and fall. One full breath includes both an inhale and an exhale.
- Set a Timer: Use a timer to measure one full minute.
- Count the Breaths: Count the number of full breaths your puppy takes in that minute. Normal rates for puppies typically range from 15 to 40 breaths per minute.
- Repeat the Process: Measure their breathing rate during multiple sleep sessions to establish a clear baseline.
If your puppy’s breathing seems unusually fast, repeat this process to confirm their rate and monitor for other signs of discomfort. Persistent or excessive rapid breathing may require a visit to the veterinarian for further evaluation.
