Common Respiratory Sounds in Pets and What They Mean

Coughing in Pets: When to Take Notice

Coughing can be a symptom of something as mild as a cold—or as serious as heart disease.

Possible Causes:

  • Kennel Cough (Canine Infectious Respiratory Disease Complex): Highly contagious and common in social settings like dog parks or boarding facilities.
  • Heart Disease: Often produces a nighttime cough or one that worsens at rest.
  • Collapsed Trachea: Most common in small breeds and causes a distinct honking sound.
  • Lung Infections, Pneumonia, or Cancer: Require prompt evaluation and treatment.

Red Flags:

  • Persistent or worsening cough
  • Coughing at night or during sleep
  • Coughing combined with lethargy, breathing difficulty, or pale/blue gums

Sneezing: When It’s More Than a Nose Tickler

A quick sneeze isn’t usually a concern—but frequent or severe sneezing can signal trouble.

Potential Causes:

  • Environmental Irritants: Dust, smoke, or perfumes.
  • Viral or Bacterial Infections: Particularly common in cats and shelter settings.
  • Dental Issues: Infections in the mouth can spread to the nasal cavity.
  • Nasal Tumors: Typically seen in older pets and require diagnostic imaging.

Red Flags:

  • Persistent sneezing with discharge (especially yellow, green, or bloody)
  • Swelling near the nose or eyes
  • Loss of appetite or energy alongside sneezing

Wheezing or Labored Breathing: Signals You Shouldn’t Ignore

Wheezing can sound like a soft whistling or rattling during breathing and may point to narrowed or inflamed airways.

Possible Causes:

  • Asthma: Especially common in cats and triggered by allergens or stress.
  • Allergic Reactions or Irritants: Smoke, cleaning products, or pollen.
  • Bronchitis or Pneumonia: Often accompanied by lethargy, coughing, and fever.
  • Heartworm Disease: Preventable but potentially life-threatening.

Red Flags:

  • Open-mouth breathing or excessive panting at rest
  • Blue or pale gums
  • Collapse or signs of severe weakness

Reverse Sneezing: Often Harmless but Still Worth Monitoring

Reverse sneezing is often seen in small breed dogs and can sound like a sudden bout of choking or rapid snorting.

Common Triggers:

  • Excitement, pulling on the leash, or allergens
  • Irritation of the soft palate or throat
  • Sometimes linked to collapsing trachea

Red Flags:

  • Episodes that become more frequent or prolonged
  • Difficulty breathing following an episode
  • Associated coughing, wheezing, or fatigue

Snoring: When It’s Normal and When It’s Not

Some snoring is normal—especially for flat-faced breeds. But changes in snoring patterns can be a clue that something is wrong.

Contributing Factors:

  • Brachycephalic Breeds: Bulldogs, Pugs, and Shih Tzus are more prone to snoring due to airway anatomy.
  • Obesity: Excess weight can worsen airway obstruction.
  • Nasal Inflammation or Polyps: May require medication or surgical intervention.

Red Flags:

  • Snoring that starts suddenly or worsens noticeably
  • Struggling to breathe during sleep
  • Episodes of choking, gagging, or interrupted sleep

When to Seek Immediate Veterinary Care

If your pet shows any of the following signs, they may be experiencing a medical emergency:

  • Difficulty breathing or gasping for air
  • Gums that appear blue, gray, or pale
  • Collapse, disorientation, or severe fatigue
  • Persistent coughing, wheezing, or reverse sneezing episodes
  • Noisy breathing that doesn’t resolve with rest

In these cases, contact Omega Veterinary Group right away.

How to Prevent Respiratory Issues in Pets

Schedule Regular Checkups

Annual (or biannual) exams help catch respiratory issues early:

  • Detect heart disease, asthma, or infection before symptoms worsen
  • Ensure vaccines are up to date
  • Discuss parasite prevention and lifestyle risk factors

See AVMA/AAHA Canine Preventive Guidelines

Reduce Environmental Triggers

You can make your home more comfortable for sensitive pets:

  • Use air purifiers and avoid smoking indoors
  • Keep bedding clean and allergen-free
  • Avoid strong scents or chemical sprays
  • Limit outdoor activity during high pollen days
