Difficulty Breathing in Dogs & Cats

Your dog or cat may be panting, but that isn't the same thing as labored breathing. Labored breathing actually means that your pet is struggling to breathe properly. Here, our Mechanicsburg vets explain what shallow breathing and difficulty swallowing in cats and dogs (difficulty swallowing sometimes accompanies labored breathing) and what to do if your pet is showing signs of labored breathing.

What is labored breathing in dogs and cats?

To identify signs of respiratory distress in your cat or dog, it's crucial to distinguish between rapid breathing (known as tachypnea) and genuine difficulty in breathing (known as dyspnea).


  • Fast breathing is a common occurrence during exercise. When you take your dog out for a run, they might pant and breathe rapidly. However, this doesn't indicate any breathing problems for your furry friend.


  • Dyspnea is the term for labored breathing in cats and dogs. This term means that your animal is actually having difficulties taking breaths, or is short of breath.

Labored breathing is a serious veterinary emergency that demands immediate medical attention. How can you determine if your pet is experiencing difficulty breathing? Dogs and cats show distinct symptoms when they have breathing problems.

What are the signs of labored breathing in dogs?

When dogs are having difficulty breathing, you are more likely to notice one of more of the following symptoms:

  • Constant panting
  • Blue-tinged gums
  • Foaming or frothing at the mouth
  • Stretching the neck out to breathe
  • Belly heaving in and out more as they breathe
  • Persistent cough, especially at night
  • An increased respiratory rate > 40 bpm
  • An unusually hoarse sounding bark
  • Sighs of anxiety such as restlessness or pacing
  • Exercise intolerance (most notably, when you take them for a walk)
  • Sitting up with a wide stance to breathe (front legs/elbows spread out)

What does labored breathing in cats look like?

It's quite common for our feline friends to hide when they aren't feeling well. Even the most attentive cat owners may find it challenging to spot signs of breathing difficulties. When a cat is having trouble breathing, it may exhibit one or more of the following symptoms:

  • Open-mouth breathing
  • Blue-tinged gums
  • Hiding in a quiet place
  • Increased respiratory rate
  • Foaming or frothing from the mouth
  • Hacking or persistent coughing
  • Body hunched close to the ground with neck extended forward

What should I do if my pet is having difficulties breathing?

If your cat or dog are showing signs of breathing issues, it's time to head to your vet. If your pet is showing signs of labored breathing, it should always be considered a veterinary emergency. In order to help your pet breathe easy, they will need to diagnose the underlying condition which is causing breathing issues in your pet.  

What causes difficulty breathing in dogs and cats?

Cats and dogs aren't always susceptible to the same conditions but some of the most common health issues that can lead to breathing difficulties in either type of animal include:

  • Trauma
  • Cancer
  • Asthma
  • Pneumonia
  • Infectious diseases 
  • Growths in the upper airway
  • Heart failure
  • Metabolic issues

How is labored breathing in pets treated?

After going through the examination process, your vet will prescribe a treatment plan based on the underlying cause of your pet's labored breathing. Some treatments for labored breathing in dogs and cats can include:

  • Oxygen therapy
  • IV fluids
  • Steroids to reduce airway inflammation
  • Bronchodilators to expand airway and increase airflow
  • Diuretics to treat fluid in lungs

Your pet's breathing difficulties may require additional diagnostic testing to determine the exact cause. Diagnostic testing may involve x-rays of the chest or abdomen, as well as an electrocardiogram or echocardiogram to assess heart function.
