Understand possible causes of apnea and key points for home observation

Apnea means breathing has temporarily or completely stopped, interrupting oxygen intake and causing carbon dioxide retention. It can impair brain and vital organ function within minutes and requires emergency veterinary help.

Emergency warning: apnea can be immediately life-threatening

Apnea means a pet has stopped inhaling and exhaling, causing rapid oxygen deprivation and carbon dioxide buildup. This can affect the brain and vital organs within a short time.

Recommended Action

Contact or go to an emergency veterinarian immediately, and keep your pet calm with the airway open during transport.

What this symptom means clinically

🐱 In cats

Cats are sensitive to low oxygen, and airway narrowing, neurologic disease, or muscle disease may strongly affect breathing.

🐶 In dogs

Dogs may develop apnea or interrupted breathing from upper airway disease, brachycephalic airway problems, neuromuscular disease, or laryngeal dysfunction.

Check whether your pet shows any of the signs below. If several apply, seek veterinary care promptly.
