If you’ve ever seen your dog breathing rapidly, you might wonder: are they just hot, or is something wrong? While panting is normal for cooling down, hyperventilation, or overbreathing, can signal something more serious, so it’s important that we know the difference.

How to Tell If Your Dog Is Hyperventilating
Panting is normal, especially in heat, after exercise, or when a dog is excited. But hyperventilation is different. In these cases, the dog is breathing out more than they are breathing in. You will see:
- Very rapid or shallow breathing that doesn't stop
- Wide eyes or signs of anxiety
- Pale or blue gums
- Stiffness or muscle tremors
- Disorientation or collapse
You might also notice your dog struggling to settle down, pacing, or whining. That’s a red flag. If they are laying down and not moving, with ragged, short breaths, it may be a medical emergency.
If you’re not sure what’s going on while you’re away, a smart pet camera like the Petcube Cam 360 can help you keep an eye on your dog’s movement and distress signs in real time.
Why Is My Dog Hyperventilating
Dogs hyperventilate for different reasons, and it’s not always obvious. Here are the most common causes:
Overheating
Dogs can’t sweat like we do. Instead, they rely on panting to release heat through evaporation from their nose and mouth. But in extreme heat or after a lot of physical exertion, they may hyperventilate to try to cool off. But, if this goes too far, it can lead to heatstroke, which is a serious medical emergency.
Stress or Anxiety
Just like people, dogs can hyperventilate during panic attacks or stressful events like fireworks or thunderstorms. It’s not as common in dogs as it is humans, but it can happen.
Pain or Illness
Anything that makes breathing difficult, such as extreme injuries (including internal injuries) or lung conditions (like pneumonia) may cause hyperventilating.
Metabolic Disorders
Conditions like diabetic ketoacidosis or poisoning can alter the body’s pH balance, triggering something called compensatory hyperventilation.
Why Is Hyperventilation Dangerous For Dogs
When a dog hyperventilates, they are breathing out more than they are breathing in (overbreathing). Too much exhaling causes a drop in carbon dioxide (a condition called hypocapnia), which in turn causes the blood to become too alkaline. This shift can trigger cerebral vasoconstriction, where blood vessels in the brain narrow, reducing blood flow.
As Dr. E.B. Brown Jr. explained, “A shift of the electrical activity of the cerebral cortex toward large slow potentials accompanies the cerebral vasoconstriction of hyperventilation... and regardless of which factor is the immediate cause, hypocapnia, hypoxia and hypoglycemia act synergistically in producing this effect.”
In simple terms, low CO₂, low oxygen, and low blood sugar can all work together to slow down brain function, causing disorientation, muscle tremors or even fainting. That’s why true hyperventilation is a full-body emergency.
But Why Doesn’t My Panting Dog Get Sick From Breathing Fast All the Time?
Here’s where it gets interesting. When a dog is panting fast, it doesn’t mean they are hyperventilating.
A veterinarian on Reddit (r/askscience) explained it best: “Dogs do have the same acid/base compensation mechanisms as humans do, and you're right that a dog breathing too much will cause alkalosis... But when dogs pant, most of that air just moves in and out of ‘dead space’,like the mouth and trachea, where no gas exchange occurs.”
In short, dogs are built for this. Their panting is shallow and mostly aimed at cooling off via evaporation, not actual deep lung exchange. Plus, their bodies compensate for minor pH shifts through metabolic pathways. So unless they’re sick or stressed, most dogs won’t develop dangerous alkalosis from normal panting.
How to Stop a Dog From Hyperventilating
If your dog starts hyperventilating, the first thing to do is stay calm as dogs often mirror our stress. Gently move them to a cooler spot and offer fresh water in case they’re overheating. Do not let them run or play until their breathing returns to normal.
If they seem anxious, give them quiet reassurance to help them settle. Keeping track of their breathing patterns can also help, and tools like the Petcube Tracker can alert you to changes even when you’re not home. If their breathing doesn’t return to normal after a few minutes, or they collapse, shake, or seem confused, it’s time to head to the vet as quickly as possible.
Conclusion
Panting is normal. But true hyperventilation means your dog’s breathing has shifted from safe to potentially dangerous. By learning the signs, knowing the causes, and acting quickly, you can keep your dog calm and cool to help return them to normal breathing.
