# Why Is My Dog Panting Heavily? — Quick answer

PETHEALTH+ (https://pethealth.org.uk/uk-pet-questions/why-is-my-dog-panting-heavily): Why Is My Dog Panting Heavily? — Quick answer. Dogs pant to cool down — heavy panting after exercise or on warm days is usually normal. Panting at rest in cool weather, with pale or blue gums, coughing, collapse, or after a hot car needs urgent vet care. Common causes include heatstroke, pain, heart disease, fever, anxiety, and obesity. Flat-faced breeds overheat faster.
