🐶 Understanding Normal vs. Abnormal Panting

🐾 What Is Panting and Why Dogs Do It

Panting is your dog’s built-in cooling system—it’s how they release excess heat and keep their body temperature in check, especially since they don’t sweat like we do. Dogs don’t sweat like humans do. Instead, they release heat through their tongue and respiratory system. You’ll probably notice your dog panting after a good run, during warm weather, or when they’re feeling super excited or playful—it’s totally normal in those moments.

🔍 When Is Night Panting Considered Normal?

Some light panting during sleep might be completely normal—especially if your pup had a stimulating evening walk or the room is warm. However, excessive, loud, or distressed panting at night could signal something more serious like pain, stress, or even illness.


🌡️ 1. Heat and Overheating

💨 Bedroom Temperature and Ventilation

If your dog’s sleeping area or your bedroom gets a bit too warm at night, they might start panting as a way to cool themselves off and stay comfortable. Dogs with thick fur or short noses (like bulldogs or pugs) are more prone to heat intolerance.

❄️ How to Keep Your Dog Cool at Night

  • Use a fan or air conditioning
  • Switch to a cooling dog bed or mat
  • Give fresh, cool water before bedtime
  • Avoid walks or exercise too close to bedtime

🧠 2. Stress or Anxiety

😟 Common Nighttime Triggers

Just like humans, dogs can feel anxious in the dark or when alone. Separation anxiety, thunderstorms, loud noises, or changes in routine can all cause nighttime panting.

🧘 How to Calm an Anxious Dog

  • Leave a piece of your clothing near their bed
  • Use a calming diffuser (like Adaptil)
  • Try natural supplements like CBD (only with vet approval)
  • Create a consistent bedtime routine

If your dog’s anxiety doesn’t let up or seems pretty intense, it’s a good idea to reach out to your vet or a professional behaviorist for help.


💥 3. Pain or Discomfort

🔎 Signs Your Dog May Be in Pain

Dogs rarely show pain openly, but signs can include:

  • Whining or yelping
  • Limping or stiffness
  • Panting without physical activity
  • Avoiding being touched

🛌 Managing Pain at Home

You can help relieve pain by:

  • Providing orthopedic bedding
  • Avoiding stairs or high jumps
  • Administering vet-approved medications
    Never give human painkillers without consulting your vet—it can be dangerous or fatal.

❤️ 4. Underlying Health Issues

❤️ Heart Problems

Panting at night can indicate heart issues, particularly in older dogs. Symptoms may include coughing, fatigue, and exercise intolerance.

🌬️ Respiratory Conditions

Dogs with respiratory diseases like bronchitis or laryngeal paralysis may struggle to breathe normally, leading to nighttime panting.

🧪 Cushing’s Disease and Other Hormonal Disorders

Cushing’s disease causes elevated cortisol levels, leading to symptoms like:

  • Excessive panting
  • Increased thirst and urination
  • Hair loss and weight gain

This condition requires a vet diagnosis and ongoing treatment.

⚖️ 5. Obesity and Poor Fitness

🐖 Why Overweight Dogs Pant More

Extra weight makes it harder for dogs to cool down. It also puts pressure on the heart and lungs, making panting more frequent—especially at night when laying down restricts airflow further.

🏃 Weight Management Tips

  • Feed a high-protein, low-carb diet
  • Ensure daily exercise (even light walks)
  • Use interactive feeders to slow down meals
  • Get a weight management plan from your vet

💊 6. Side Effects of Medication

💉 Common Medications That Cause Panting

Some prescriptions may cause panting as a side effect, including:

  • Prednisone (a steroid)
  • Thyroid medications
  • Pain relief meds

📝 What You Should Do

  • Check the side effects listed on the medication info
  • Keep a log of symptoms
  • Discuss alternatives or dosage adjustments with your vet

🧓 7. Aging and Cognitive Decline

🧠 Canine Cognitive Dysfunction Syndrome (CDS)

Senior dogs may experience confusion at night. This condition is similar to dementia in humans and may cause:

  • Restlessness
  • Night waking
  • Increased panting due to stress

🌙 Night Waking and Disorientation

Aging dogs might wake up disoriented, leading to pacing, panting, and even barking.

Helpful tips:

  • Keep a dim night light on
  • Stick to a strict bedtime routine
  • Consider a vet visit for supplements or medications to ease symptoms
