A dog panting heavily at night, when it should be resting, is different from panting after a walk. Because it happens while you're trying to sleep and the dog is calm, it's a signal worth understanding rather than ignoring.
Panting at night in a resting dog can mean heat, anxiety, pain, or a medical problem like heart or respiratory disease, or Cushing's disease. Occasional panting on a warm night is usually fine, but new, persistent, or heavy night panting in a calm dog warrants a vet, especially with other signs. Pain and anxiety are common, treatable causes; some medical causes are serious.

Why night panting is different
Panting cools a dog or signals stress. After exercise or in heat, it's normal. But a dog panting hard while resting in a cool room, at night, isn't cooling off, so something else is driving it. That context is exactly what makes night panting worth a closer look. [1]
The common causes
Heat or a too-warm sleeping spot; anxiety (including nighttime or separation-related); pain, which dogs often reveal at night when distractions fade; and medical conditions like heart disease, respiratory problems, or Cushing's disease (which frequently causes increased panting). Older dogs with new night panting deserve particular attention.
When to see a vet
New or worsening night panting, panting with restlessness or difficulty settling, pale or bluish gums, coughing, a pot-bellied appearance, or any breathing difficulty warrants a vet, urgently if breathing looks labored. Because pain is a common cause, a vet can identify it and, for something like arthritis, prescribe safe relief.
What helps
Address the obvious first: a cooler, comfortable sleeping area and a calm bedtime routine. If those don't resolve it, a vet finds the cause. For pain-related panting from arthritis, a vet may prescribe relief such as Galliprant. Never give human painkillers.
Frequently asked questions about dog panting at night
Why does my dog pant at night but not during the day?
At night, distractions fade and pain or anxiety show more; a warm sleeping spot or a medical cause can also be behind it.
Is night panting an emergency?
Labored breathing or pale/blue gums is an emergency. New persistent panting warrants a vet even if not urgent.
Can pain cause night panting?
Yes, pain is a common cause dogs reveal at night. A vet can identify and treat it.
