Why is my dog breathing so fast?

If your pup is breathing fast without apparent cause, it can be worrying. Today our VRCC vets share some reasons why your dog may be breathing hard and when it's time for your dog to see the vet.

What counts as fast breathing in dogs?

To be able to spot irregular breathing, we need to know what a healthy respiratory (breathing) rate for a dog is. An average healthy pet should take between 15 - 35 breaths per minute when at rest. (Of course, while exercising, your pooch will naturally breathe faster).

Anything above 40 breaths per minute while your dog is resting is considered abnormal and worth investigating.

That said, not all panting is bad or a sign of distress. Panting helps your pup regulate their body temperature, cooling them down and allowing moisture and heat to dissipate from the tongue, the mouth, and the upper respiratory tract.

Unlike people, your dog can't sweat to cool down; instead, they need to breathe fast to allow oxygen to circulate efficiently through the respiratory system. Rapid breathing allows a dog’s body to get back to a normal temperature.

How do I know if my dog is breathing too fast?

To determine whether your dog is breathing abnormally fast, simply count your dog’s respiratory rate while they are sleeping or resting. It can be a good idea to do this when you are not concerned, to have a clear understanding of your pet's normal respiratory rate. Anything under 30 breaths per minute is considered normal, anything above 35 is a cause for concern.

Why is my dog breathing fast?

Your pet's rapid breathing could be a sign that your dog is suffering from an illness, injury, or other condition that should be evaluated by your veterinarian as soon as possible.

Dog breeds with 'squished faces' or shortened snouts such as Boston terriers, Boxers, and Pugs are more predisposed to breathing issues and should always be closely monitored by pet parents for any signs of respiratory difficulties.

Some potential causes of fast or heavy breathing in dogs include:

  • Asthma
  • Breed Characteristics
  • Kennel Cough
  • Laryngeal Paralysis
  • Issues affecting Windpipe 
  • Bacterial Respiratory Infection
  • Fungal Respiratory Infection
  • Pressure on the Windpipe
  • Stiffening of Airways
  • Smoke Inhalation
  • Collapsing Windpipe
  • Lung Diseases (e.g. cancer)
  • Parasites
  • Pneumonia
  • Compressed Lungs
  • Hernia
  • Heat Stroke
  • Anemia
  • Nausea
  • Pain
  • Effects from Medication 
  • Exercise

When should I be concerned about my dog's rapid breathing?

If your dog is breathing fast while at rest or sleeping, they could exhibit symptoms of respiratory distress. Contact your primary vet if you notice any of the following signs:

  • Engaging stomach muscles to help breathe
  • Reluctance to drink, eat, or move
  • Pale, blue-tinged, or brick-red gums
  • Uncharacteristic drooling
  • Open-mouthed breathing
  • Heavy, fast breathing (sounding different from their normal panting)

How will the vet diagnose the cause of my dog's fast breathing?

Your dog's primary vet will perform a full physical examination to determine whether the issue is in the heart, circulatory system, lungs, airway, neck, head, or another area. Your pet's overall health condition may also be caused by an underlying issue.

Any previous medical issues that your pet has experienced need to be disclosed to your vet, who may recommend diagnostic tests such as X-rays to check the heart, lungs, and abdomen for issues like broken ribs or lung tumors.

The veterinarian will also look for any signs of anxiety, stress, or other psychological factors that could be causing fast breathing.

What are the treatments for fast breathing in dogs?

Treatment for your pup's fast breathing will be determined by the underlying cause. Pain relief, intravenous fluids with calcium, or other medications are some of the treatment methods available to help remedy your furry friend's problem.

If your pet's rapid breathing is caused by stress or anxiety, special training with a certified dog behaviorist may be required.

Regardless of the cause of your pet's breathing difficulties, it is likely that rest and oxygen therapy will be necessary, with most dogs being well enough to receive treatment at home and others needing more specialized care or hospitalization. Your primary vet will be able to support your pup's recovery and offer guidance for at-home care.
