A dog panting at night is often just too warm: a hot room, a thick bed or a closed crate can all do it, and cooling the room or the bed usually settles it. But panting while resting or sleeping is often abnormal, according to PetMD, and can be a sign of pain, anxiety or illness. If it is new, heavy or keeps your dog awake, call your vet rather than only buying a cooling mat.
Panting is how dogs cool down, since they cannot sweat like people. So the first check is simple: is your dog too warm? If the room is cool and your dog still pants, the cause is probably something else.
The common, usually harmless causes
PetPlace lists these as everyday explanations:
- A warm room. Lowering the temperature a few degrees may be all that is needed.
- Recent exercise or excitement, which raises body heat for a while.
- Vivid dreams in REM sleep, which can bring a short burst of quick breathing.
- Mild stress from routine changes, storms or fireworks.
Also check the bed. A thick foam bed, a fleece cover or a crate with a blanket over it holds heat, and a dog who warms their own spot may have no cool place left.
When panting at night is a warning sign
PetMD says panting at rest or in sleep "is often abnormal," and that healthy dogs do not usually pant without exercise or excitement. Possible causes include:
- Pain, such as arthritis or an injury. A dog who circles, lies down, gets up and pants may be uncomfortable.
- Anxiety, including separation anxiety.
- Medications, such as steroids like prednisone.
- Medical conditions, including heart or lung disease and hormonal problems such as Cushing's disease.
- Cognitive changes in older dogs (PetPlace).
- Flat-faced breeds such as Pugs, Bulldogs and French Bulldogs overheat and struggle with airways more easily, and Labs and Goldens can develop laryngeal paralysis, which causes harsh panting (PetMD).
Call your vet if the panting does not match the temperature or activity, if it comes with lethargy, poor appetite, shaking, coughing or gray, blue or bright red gums, if the sound changes, or if it is new in an older dog (PetMD, PetPlace). PetPlace suggests keeping a written log and short videos to show the vet.
What to try tonight
- Cool the room a few degrees and make sure there is fresh water.
- Move the bed off a warm spot, away from heaters, direct sun through a window and sealed corners.
- Swap thick bedding for a cooler surface (below).
- Avoid heavy exercise or a big meal right before bed (PetPlace).
- Settle stress with a consistent bedtime routine and quiet; ask your vet before trying calming products.
What we'd buy if heat is the cause
PetMD lists a cooling mat among ways to help a dog who is panting from heat. These suit a dog who is panting because the bed is warm, and none of them treat an illness.
K&H Coolin' Pet Pad. A water-filled pad with no plug that you can put on a bed, floor or crate. Check the size against your dog lying stretched out.
Green Pet Shop Cool Pet Pad. A cooling mat for indoor use. Check the maker's size chart, and skip mats for dogs who chew bedding.
Coolaroo Elevated Pet Bed. A raised mesh bed that lets air flow underneath, a good swap if your dog overheats on foam. See our elevated dog bed guide for fit.
More options, including crate and car picks, are in our best cooling mats for dogs guide. If your dog is stiff or restless rather than hot, an orthopedic bed may suit better, after your vet has checked for pain.
This guide is general information, not veterinary advice. Panting at rest can be a sign of pain, heart or lung disease, hormonal problems or heatstroke. Call your vet if panting is new, heavy, keeps your dog awake or comes with pacing, coughing, trembling, collapse or gray, blue or bright red gums. If you think your dog is overheating, move them somewhere cool, offer water and call a vet or emergency hospital right away.
FAQs
Why is my dog panting at night when it is not hot?
Possible reasons include pain, anxiety, medication side effects, or heart, lung or hormonal conditions. Panting at rest is often abnormal, so call your vet, especially if it is new.
Why is my old dog panting at night?
Pain, anxiety and cognitive changes are common in seniors, and PetPlace advises a vet visit if panting is new or worsening in an older dog.
Is it normal for a dog to pant while sleeping?
A short burst after a vivid dream can be normal. Ongoing fast breathing during sleep is worth a call to your vet.
Does a cooling mat stop night panting?
It can help if the cause is heat. If the room is cool and your dog still pants, a mat will not fix the underlying reason.
