Why Do Dogs Hyperventilate?

Have you noticed your dog breathing fast?

Are you worried they may be hyperventilating?

Obviously, this is a significant issue with potentially serious health implications for your dog.

So, the first thing to say is if you have any serious concerns about your dog’s breathing and health, please take them to your vet for a check-up.

With that said, in this article, we will answer the question – why do dogs hyperventilate – and cover what you need to know about this issue.

Before we look at the potential causes, you must first figure out if the dog is hyperventilating or just breathing heavily (the difference is important).

How to Know if Your Dog is Hyperventilating or Just Breathing Fast

If your dog is breathing heavily after exercise and the breathing slows down over time, then they are not hyperventilating.

However, if the breathing is more persistent and not just heavy, it may well be hyperventilation.

Signs of dog hyperventilating can include:

  • Rapid and shallow breathing.
  • Breathing with their mouths open (gasping).
  • Struggling to breathe deeply.
  • Abnormal drooling.
  • Pale or blue lips and gum.
  • Weakened body posture.

If they are breathing fast and exhibit some of the above symptoms, they are most likely hyperventilating, and you need to pay attention until it is resolved.

Why Is My Dog Hyperventilating and Breathing Fast?

There are many reasons why your dog might start breathing fast or hyperventilating.

Here is a list of the most common reasons:

  1. Over Excitement
  2. High Levels of Stress
  3. Reverse Sneezing (aka Inspiratory Paroxysmal Respiration)
  4. Heat Stroke – Being Too Hot
  5. Cushing’s Disease
  6. Respiratory Diseases
  7. Anemia
  8. Metabolic Acidosis
  9. Anaphylaxis
  10. Hypoxemia
  11. Allergies
  12. Heart Failure
  13. Laryngeal Paralysis
  14. Tracheal Collapse
  15. Brachycephalic Obstructive Airway Syndrome (BOAS)

Now we can look at this list in more detail and see which one is the most likely candidate for your pet dog.

1. Over Excitement

This should be pretty easy to spot and is unlikely to be anything to worry about.

Sometimes when dogs get overexcited, they can either breathe much faster (panting) or start hyperventilating (rapid and shallow breathing).

It should be self-evident what caused it.

For example, if your dog was very excited and then started breathing fast, the chances are the excitement was the cause.

Just do your best to help them calm down and see if their breathing returns to normal.

If it does, that’s great, keep an eye on the dog and see if it happens again next time they get excited (if it does, a check-up at the vet’s is a good idea).

If the hyperventilating doesn’t stop once the dog is less excited, you should take them to the vet to ensure there isn’t something seriously wrong with them (if you can’t afford vet bills, please take a look here for help).

2. High Levels of Stress

Similar to the previous point, if your dog has suffered much higher than usual levels of stress, this could trigger an attack of hyperventilation.

Do your best to calm them down.

Hopefully, their breathing will return to normal, but please take your dog to a vet if it doesn’t.

3. Reverse Sneezing (aka Inspiratory Paroxysmal Respiration)

Reverse sneezing, or giving it its medical name Inspiratory paroxysmal respiration, is a spasm that causes fast breathing out through the dog’s nose.

Reverse sneezing isn’t hyperventilating, but it is easy to confuse the two.

If your dog is breathing in sharply and fast through its nose, it is probably reverse sneezing.

It isn’t dangerous but can indicate an underlying medical issue, so if it persists, take your dog to the vet.

And this video will give you a good idea of what’s going on with reverse sneezing:


4. Heat Stroke – Being Too Hot

Dogs do not have the same ability to cool down through their skin that humans have.

Instead, dogs use breathing through their mouths to regulate their body temperature.

If your dog gets dangerously overheated, it might start to hyperventilate, making an already dangerous situation even worse.

If this happens, do your best to cool your dog down and keep them calm.

However, if the hyperventilating persists, take them to the vet.

5. Cushing’s Disease

Cushing’s disease causes a dog to lose the ability to regulate cortisol effectively.

A side effect of this can be hyperventilating.

This video from a qualified veterinarian gives some great advice if you are worried your dog may be suffering from Cushing’s disease.

6. Respiratory Diseases

A few different canine respiratory diseases can cause hyperventilating in dogs.

As mentioned, if you think your dog might have a medical condition, a visit to the vet is the best option.

Some respiratory diseases can be life-threatening for dogs if not treated, so please take action sooner rather than later.

7. Anemia

Anemia is a condition that can affect dogs as well as humans.

When it occurs, dogs have a lower-than-normal amount of red blood cells in their bodies.

Anemia can cause a range of symptoms, including hyperventilating, bloody nose, bloody stools, and bloody urine.

8. Metabolic Acidosis

Metabolic acidosis is when a dog’s internal pH balance is altered due to an increase in acidic production, and it can then cause the dog to hyperventilate.

Metabolic acidosis is often a sign of something more serious such as diabetes or even kidney failure.

Hence, if your dog shows any other signs of being unwell, please take them to the vet.

9. Anaphylaxis

Canine anaphylaxis, also called an anaphylactic reaction, is an extreme reaction to an allergen a dog comes into contact with.

In some cases, anaphylactic reactions can trigger hyperventilating in dogs, so if your dog hyperventilates and it’s a one-off, it could be caused by an allergic reaction.

You should do your best (with your vet) to figure out what the allergic reaction was caused by and then try to keep your dog away from that substance.

10. Hypoxemia

Hypoxemia is a severe condition where the dog has lower than-usual oxygen levels in its blood.

As a result, one of the potential symptoms is hyperventilating along with mouth breathing, coughing, tachycardia (elevated heart rate), and gagging.

11. Allergies

If your dog has allergies and comes into contact with a substance they are allergic to, this can cause an anaphylactic reaction, and as a result, your dog might start to hyperventilate.

If you know your dog has allergies, do your best to keep them away from whatever they are allergic to, and if they come into contact with it, keep a close eye on how they react.

If you suspect they may have allergies, keep notes of anything new they might have come into contact with, and speak to your vet about allergy testing.

12. Heart Failure

Caine hyperventilating can be a symptom of heart disease or heart failure.

If a dog is suffering from heart failure and hyperventilation, they will typically display a range of other symptoms, including fatigue, increased need for sleep, loss of appetite, increased thirst, and general signs of malaise.

13. Laryngeal Paralysis

Laryngeal paralysis is when the larynx (also known as the voice box) fails to open correctly when the dog breathes in.

This can cause hyperventilation and other symptoms, such as coughing, wheezing, and difficulty swallowing.

14. Tracheal Collapse

Tracheal collapse is a progressive respiratory condition that causes the trachea (also known as the windpipe) to collapse gradually.

This can cause breathing problems, including hyperventilation, coughing, wheezing, and gagging.

15. Brachycephalic Obstructive Airway Syndrome (BOAS)

Brachycephalic obstructive airway syndrome, or BOAS for short, is the name for short-nosed dogs’ breathing issues.

Pugs, English Bulldogs, and French Bulldogs are three traditional breeds that suffer from this condition.

BOAS can cause a range of health and respiratory problems, including hyperventilation.

Signs and Symptoms of Canine Hyperventilating

If your dog is hyperventilating, it will show some of the following symptoms:

  • Fast, open-mouthed, shallow breathing.
  • Wheezing or snorting.
  • Blue or pale gums and lips.
  • An increased heart rate.
  • Weakness, fainting or collapsing.

What to Do if Your Dog is Hyperventilating?

If you think your dog is hyperventilating, you first need to find out what could be causing it.

Are they overexcited, scared, or showing signs of illness?

Have they been stung by a bee or wasp?

Has anything unusual happened that could have triggered the breathing problem?

If you can figure out why they have gone into hyperventilation, you can reduce or eliminate the trigger.

Or, if you don’t know why it’s happening, stay with your dog and try to comfort them until it passes.

Once their breathing is back to normal, the safest thing is to get them to the vet for a check-up to ensure there isn’t something more serious underlying their breathing issues.

How to Prevent Your Dog from Hyperventilating

It is impossible to eliminate all chances of your dog hyperventilating, but you can reduce them by studying the list of causes above.

Getting regular check-ups at your local vet is an essential first step, then making sure the dog’s lifestyle is as happy and healthy as possible is also a great idea.

By looking after their general health and well-being, you will reduce the likelihood of the conditions and triggers that can cause hyperventilating.

Should You be Concerned About Your Dog if it Hyperventilates?

It all depends on the cause of the hyperventilation, so there is no simple answer to this, but the best action is to speak to your vet and pay close attention to their advice.
