Diseases Behind a Dog’s Rapid Panting
📝 Summary
Panting normally cools a dog briefly after exercise, but constant rapid panting can mean respiratory disease, collapsed trachea, airway obstruction, hypoxia, bronchitis, pneumonia, heartworm, heart failure, or obesity. Identify the cause to treat it correctly.
1 When Panting Is Normal
Panting uses only the upper airway for quick cooling and can reach over a hundred breaths a minute, normally appearing only briefly before returning to normal; it also follows hard exercise as the dog steadies its breath.
2 Disease Causes
Respiratory disease commonly shows as rapid panting.
Collapsed trachea triggers panting and a goose-like cough from exercise or excitement.
Airway obstruction adds coughing and uneven breathing.
Hypoxia forces hard, rapid breathing with purple lips, gums, and tongue as oxygen fails to reach the lungs.
Bronchitis or pneumonia cause panting; bronchitis may bring retching and cough, pneumonia labored breathing, fever, lethargy, and cough.
Heartworm (late stage) adds cough, lethargy, anemia, jaundice, or swollen belly; heart failure causes panting after slight exercise plus low activity, fatigue, and poor appetite.
Lack of exercise and obesity cause rapid panting; start a weight-loss plan.
