Dog Health • Breathing

Why is my dog breathing so fast?

Dogs normally pant after exercise or in warm conditions, but rapid breathing while resting or sleeping can reflect pain, fever, heart disease, lung disease, anemia or other problems.

Quick answer

Watch breathing effort as well as rate. A dog using the abdomen strongly, extending the neck, unable to lie down, becoming blue/gray or collapsing needs emergency care.

Panting versus rapid resting respiration

Panting is open-mouth breathing used for heat regulation and can also occur with stress or pain. Resting respiratory rate is best counted when a dog is asleep or quietly resting and not panting. One rise and fall of the chest equals one breath.

Why trends matter

A single number does not diagnose disease, but a persistent increase from your dog's normal sleeping respiratory rate can be useful information, especially in dogs with known heart or lung disease.

Emergency signs: labored breathing, blue/gray gums, collapse, severe weakness, coughing up foam, inability to rest comfortably or rapidly worsening breathing.
