Why Do Dogs Pant?
Dogs don’t sweat like humans do. Instead, they regulate their body temperature primarily through panting. When a dog pants, moisture evaporates from their tongue and upper respiratory tract, cooling their body down. While this is completely normal during exercise or hot weather, panting that seems excessive or occurs at odd times warrants a closer look.
Common Reasons Why Your Dog Is Panting So Much
1. Heat and Exercise
One of the most straightforward reasons for panting is physical exertion or warm weather.
Signs to watch for:
- Panting during or after a walk, run, or playtime.
- Panting on hot, humid days, even with minimal activity.
What to do:
Ensure your dog has access to cool water, shaded areas, and limit outdoor activities during peak heat hours. Use cooling mats or vests for high-risk breeds like Bulldogs or Pugs.
2. Stress, Anxiety, or Excitement
Dogs also pant when they’re stressed, anxious, or overly excited.
Common triggers:
- Thunderstorms
- Fireworks
- Vet visits
- Car rides
- New environments
Behavioural signs:
Panting accompanied by pacing, whining, yawning, or lip licking.
What to do:
Offer a calm environment, consider anxiety wraps, or talk to your vet about behaviour modification strategies or calming supplements.
3. Pain or Discomfort
Panting can be a subtle signal of pain in dogs. Unlike humans, dogs often hide discomfort, making panting one of the few visible clues.
Conditions that cause pain-related panting:
- Arthritis
- Abdominal pain (e.g., pancreatitis)
- Injuries
- Dental issues
What to do:
If your dog is panting more than usual and showing other signs like limping, loss of appetite, or restlessness, consult your veterinarian promptly.
4. Illnesses That Cause Excessive Panting
Some medical conditions can trigger abnormal panting.
A few to be aware of:
| Condition | Symptoms in Addition to Panting |
| Heart Disease | Coughing, fatigue, blue gums |
| Cushing’s Disease | Hair loss, increased thirst/urination |
| Respiratory Disorders (e.g., pneumonia, laryngeal paralysis) | Laboured breathing, coughing |
| Anaemia | Pale gums, lethargy |
What to do:
Schedule a veterinary exam, including bloodwork, chest X-rays, or an ultrasound if recommended.
📌 Pro Tip:
Older dogs, especially those over 10-13 years, are more prone to conditions like heart disease and Cushing’s, making regular wellness checks essential.
5. Medication Side Effects
Certain medications can cause increased panting as a side effect.
Common culprits:
- Prednisone (a corticosteroid)
- Opioids
- Thyroid medications
What to do:
If you’ve recently started your dog on a new medication and notice increased panting, consult your vet about possible adjustments or alternatives.
6. Overheating and Heatstroke (Medical Emergency)
Signs of heatstroke:
- Excessive, rapid panting
- Drooling
- Weakness
- Vomiting or diarrhoea
- Collapse
What to do:
Move your dog to a cool area, offer small amounts of water, wet their fur with lukewarm water, and get to the vet immediately.
