It can be worrying when a dog pants and shakes every night, particularly when the behavior keeps happening even though they seem relatively comfortable during the day.
Repeated nighttime episodes can make it difficult for both you and your dog to get a restful night’s sleep.
Panting and shaking are signs that something may be affecting your dog’s comfort or behavior.
Sometimes the cause is temporary, but recurring symptoms can also be associated with pain or an underlying health condition.

Dog Panting and Shaking Every Night: Why It Happens
A dog may pant and shake every night because of anxiety, pain, discomfort, nausea, being too warm, age-related changes, medication effects, or an underlying medical condition.
The fact that the episodes happen specifically at night can provide useful information, particularly if they occur after your dog lies down or wakes from sleep.
The pattern of the behavior also matters. A dog that pants and trembles briefly after hearing a noise may have a different problem from one that repeatedly wakes up, paces, and cannot settle.
Dog Panting and Shaking Every Night: Common Causes
Anxiety or Fear
Anxiety is one possible explanation when a dog repeatedly pants and shakes at night. The house may be quieter, but dogs can still respond to unfamiliar sounds, outdoor activity, storms, changes in routine, or other nighttime triggers.
An anxious dog may pace, seek reassurance, hide, whine, or repeatedly move between sleeping areas. Some dogs may appear completely normal again once morning arrives.
If the behavior is new or significantly different from your dog’s usual nighttime routine, however, it is worth considering physical causes as well.

Pain or Physical Discomfort
Pain can cause panting and trembling even when a dog is resting. Arthritis, muscle or joint problems, injuries, abdominal discomfort, and dental problems can all make it difficult for a dog to settle.
Stiffness, difficulty getting up, reluctance to climb stairs, changes in sleeping position, or sensitivity when touched may be noticed.
Pain can become more noticeable when there are fewer distractions at night. A dog that repeatedly pants, shakes, and changes position may be uncomfortable rather than simply restless.
Being Too Warm
Dogs pant to regulate body temperature. A warm bedroom, heavy bedding, poor ventilation, or a naturally warm coat can cause nighttime panting.
A dog that is too warm may move away from its bed, seek a cooler surface, drink more water, or remain restless.
Improving the sleeping environment may help if temperature is the cause. Panting that continues despite comfortable conditions should not automatically be attributed to heat.
Gastrointestinal Discomfort
Nausea can cause panting, trembling, lip licking, drooling, repeated swallowing, and restlessness. Some dogs become particularly unsettled at night when they are experiencing stomach discomfort.
Other signs can include vomiting, diarrhea, reduced appetite, grass eating, or frequent changes in position.
If panting and shaking occur alongside digestive symptoms, the underlying gastrointestinal problem may need veterinary assessment.

Age-Related Cognitive Changes
Older dogs can develop changes in their sleep-wake patterns and nighttime behavior. A senior dog may become confused or restless after dark and may pace, vocalize, stare, or have difficulty settling.
Panting and trembling may occur alongside this nighttime restlessness.
Cognitive changes should not be assumed to be the cause without considering other medical problems. Pain, illness, hearing or vision changes, and other conditions can also disturb sleep in older dogs.
Heart or Respiratory Problems
Panting when a dog is resting can sometimes indicate a respiratory or cardiovascular problem. Dogs affected by these conditions may also cough, tire easily, have reduced exercise tolerance, or breathe differently.
Some dogs become more uncomfortable when lying down or trying to sleep.
Recurring nighttime panting should be discussed with a veterinarian if it is unexplained, especially when coughing or breathing changes are also present.
Medication Effects
Some medications can affect a dog’s appetite, thirst, sleep, behavior, or breathing pattern. Certain treatments may make dogs restless or cause increased panting.
If the nighttime episodes started after a medication was introduced, changed, or stopped, tell your veterinarian what your dog has received.
Do not change the dose or discontinue a prescribed medication without veterinary guidance.
Other Medical Conditions
A range of other illnesses can cause panting, trembling, restlessness, or changes in sleep. Fever, hormonal disorders, metabolic problems, neurological conditions, and other sources of discomfort can produce similar signs.
The symptoms alone cannot reliably identify the cause.
If your dog pants and shakes every night without an obvious explanation, a veterinary examination can help determine whether an underlying health problem is contributing.
When to Call or Visit the Vet
Occasional panting or trembling may have a simple explanation, but symptoms that occur every night are worth discussing with a veterinarian.
Seek veterinary attention immediately if you notice:
Panting that continues while your dog is resting
Repeated or worsening shaking
Difficulty breathing
Coughing or unusual breathing
Inability to settle because of apparent pain
Vomiting or significant diarrhea
Loss of appetite or unexplained weight loss
Difficulty standing or walking
Collapse, severe weakness, or abnormal responsiveness
Dog Panting and Shaking Every Night: Treatment
Veterinary treatment for a dog that pants and shakes every 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 every night may be experiencing anxiety, pain, nausea, overheating, age-related changes, medication effects, or an underlying medical condition.
Repeated nighttime symptoms should not automatically be dismissed as a behavioral issue.
Pay attention to the timing and pattern of the episodes and watch for changes in appetite, mobility, breathing, digestion, or behavior.
Avoid giving human medications or sedatives without veterinary guidance.
If your dog continues panting and shaking every night, particularly while resting, arrange a veterinary examination.
Early evaluation can help identify the cause and improve your dog’s comfort and ability to rest.
