It can be unsettling to notice your dog panting and shaking at night when they seem comfortable during the day.
A sudden change in nighttime behavior can leave owners wondering whether their dog is anxious, too warm, in pain, or experiencing another health problem.
Occasional panting or trembling can happen for harmless reasons, but repeated episodes deserve attention, particularly if the behavior is new or becoming more frequent.

Dog Panting and Shaking at Night Only: Why It Happens
A dog may pant and shake at night because of anxiety, discomfort, pain, an unsuitable sleeping environment, nausea, or another medical or behavioral problem.
Some dogs become more restless when the house is quiet, while others may experience physical discomfort that is more noticeable when they are trying to settle down.
The timing of the episodes is useful information. Note whether the panting and shaking happen after your dog lies down, wakes suddenly, hears a noise, needs to go outside, or occurs without an obvious trigger.
Dog Panting and Shaking at Night Only: Symptoms
Depending on the underlying problem, other symptoms may occur at the same time, including:
Rapid or heavy breathing
Trembling or shaking
Restlessness
Pacing around the house
Difficulty settling down
Whining or vocalizing
Frequent position changes
Increased clinginess or unusual behavior
Dog Panting and Shaking at Night Only: Common Causes
Anxiety or Fear
Anxiety can cause panting and trembling, particularly when the environment becomes quiet at night.
Dogs may react to sounds that owners barely notice, such as distant traffic, animals outside, storms, or changes within the home.
An anxious dog may pace, seek attention, hide, whine, or repeatedly change sleeping locations.
If the episodes occur around a predictable trigger, anxiety may be contributing.
However, new nighttime anxiety should not automatically be assumed to be behavioral, especially in an older dog. Physical discomfort can produce similar signs.

Pain
Pain can cause panting and shaking even when a dog is resting. Arthritis, injuries, abdominal discomfort, dental problems, and other painful conditions may become more noticeable when a dog is trying to sleep.
A dog with pain may repeatedly get up and lie down, hesitate before climbing stairs, have difficulty getting comfortable, or become reluctant to move.
If your dog pants and shakes mainly after settling down, pain should be considered, particularly if there are changes in mobility or sleeping habits.
Being Too Warm
Panting is an important way dogs regulate body temperature. A warm room, thick bedding, poor ventilation, or other environmental factors can cause nighttime panting.
Some dogs may also become restless or uncomfortable when overheated.
Make sure your dog’s sleeping area is comfortably ventilated and that bedding is appropriate for the temperature. If panting continues despite a comfortable environment, another cause should be considered.
Nausea
Nausea can cause panting, trembling, restlessness, lip licking, drooling, and repeated swallowing.
Some dogs become particularly unsettled at night when they are experiencing stomach discomfort.
Vomiting, diarrhea, reduced appetite, grass eating, or changes in bowel movements may occur as well.
If nighttime panting and shaking are accompanied by gastrointestinal symptoms, veterinary assessment may be appropriate.
Age-Related Cognitive Changes
Older dogs can develop changes in their sleep-wake cycle and behavior. A senior dog may become restless, confused, or anxious at night and may pace, stare, vocalize, or have difficulty settling.
Panting and shaking may occur alongside this nighttime restlessness.
Cognitive changes should be considered only after medical causes have been evaluated.
Pain, illness, vision changes, and other problems can also disrupt sleep in senior dogs.

Respiratory or Heart Problems
Panting at rest can sometimes be associated with respiratory or cardiovascular problems.
Dogs with these conditions may have difficulty breathing, cough, tire easily, or show reduced exercise tolerance.
Some dogs with heart or respiratory disease may become more uncomfortable when resting or lying down.
Persistent or unexplained panting at night should therefore be discussed with a veterinarian, particularly if it is new or occurs alongside coughing or breathing changes.
Medication Effects
Some medications can affect a dog’s breathing, appetite, thirst, sleep, or behavior. Certain treatments may make a dog restless or cause increased panting.
If the nighttime episodes began after starting, stopping, or changing a medication, tell your veterinarian exactly what your dog has received.
Do not change the dose or discontinue prescribed medication without veterinary guidance.
Other Medical Conditions
Pain, fever, hormonal disorders, metabolic problems, and other illnesses can sometimes cause panting, trembling, or restlessness.
These conditions may not produce obvious symptoms at first. Changes in drinking, urination, appetite, weight, energy, or behavior can provide additional clues.
If your dog’s nighttime episodes are persistent or unexplained, a veterinary examination can help determine whether an underlying medical condition is involved.

When to Call or Visit the Vet
Repeated nighttime panting and shaking should be discussed with your veterinarian if the behavior is new, persistent, worsening, or accompanied by other changes. Seek veterinary attention promptly if you notice:
Panting that continues while your dog is resting in a comfortable environment
Repeated or worsening shaking
Difficulty breathing or unusually rapid breathing
Coughing or weakness
Difficulty standing or walking
Vomiting or severe diarrhea
Significant loss of appetite
Obvious pain or inability to settle
Collapse, severe weakness, or abnormal responsiveness
Dog Panting and Shaking at Night Only: Treatment
Veterinary treatment for a dog that is panting and shaking at night starts with a thorough examination, including assessment of the heart, lungs, temperature, musculoskeletal system, neurological function, and overall health.
The veterinarian may recommend blood tests, X-rays, or other diagnostic imaging when appropriate to identify problems that are not visible externally, while additional testing may be performed when heart, respiratory, hormonal, or neurological disease is suspected.
Treatment may include prescription pain relief, medication for nausea or anxiety when appropriate, treatment for an underlying infection or other illness, environmental adjustments, or other targeted therapy based on the diagnosis.
Key Takeaway
A dog panting and shaking at night only may be reacting to anxiety, warmth, pain, nausea, age-related behavioral changes, medication effects, or an underlying medical condition.
The fact that your dog appears normal during the day does not always rule out a health problem.
Keep the sleeping environment comfortable, observe what happens during each episode, and record videos when possible.
Avoid giving human medications or sedatives without veterinary guidance.
If nighttime panting and shaking persist, worsen, or occur alongside breathing problems, weakness, pain, vomiting, appetite changes, or other concerning symptoms, contact your veterinarian.
Identifying the underlying cause can help your dog rest more comfortably and safely.
