It can be unsettling to see a senior dog panting and shaking at night, especially when this behavior is new or happens repeatedly.
Older dogs may develop changes in their sleep patterns, but nighttime panting and trembling can also be signs that your dog is uncomfortable.
Some causes may be relatively simple, while others require veterinary attention.
Paying attention to when the symptoms begin, how long they last, and what other changes occur can help your veterinarian understand what is happening.

Senior Dog Panting and Shaking at Night: Why It Happens
A senior dog may pant and shake at night because of pain, anxiety, age-related cognitive changes, overheating, nausea, medication effects, or an underlying health condition.
Older dogs can also have several problems at the same time, making it important to consider changes in their overall health rather than focusing on the nighttime behavior alone.
The pattern can provide useful clues. For example, a dog that becomes restless when lying down may be uncomfortable, while a dog that wakes, paces, and appears confused may be experiencing a change in nighttime behavior.
Senior Dog Panting and Shaking at Night: Symptoms
Depending on the underlying problem, other symptoms may occur at the same time, including:
- Pacing during the night
Difficulty settling
Repeatedly changing sleeping positions
Whining or vocalizing
Nighttime confusion
Increased need for reassurance
Senior Dog Panting and Shaking at Night: Common Causes
Pain or Arthritis
Pain is an important consideration when an older dog becomes restless at night. Arthritis and other joint problems can make lying down, getting up, or changing positions uncomfortable.
A painful senior dog may pant, tremble, pace, or repeatedly move between sleeping areas. During the day, the dog may also appear stiff, move more slowly, hesitate on stairs, or be reluctant to jump.
Pain can often be managed once its source is identified, but persistent nighttime discomfort warrants a veterinary examination.

Anxiety and Stress
Senior dogs can become more sensitive to changes in their surroundings or routine. Anxiety may cause panting, trembling, pacing, whining, and difficulty settling at night.
Sounds outside, storms, changes in the household, separation from an owner, or other disturbances may contribute.
If the behavior is new, however, anxiety should not automatically be assumed to be the cause. Pain, illness, and sensory changes can produce similar behavior in older dogs.
Canine Cognitive Dysfunction
Some senior dogs develop age-related changes in brain function that affect their sleep-wake cycle and behavior. Affected dogs may become restless or confused at night and sleep more during the day.
Other changes can include pacing, staring, getting stuck in familiar areas, increased vocalization, or changes in interaction with family members.
Panting and shaking may accompany nighttime restlessness, although these signs can also have other causes. A veterinarian should evaluate new behavioral changes in an older dog to rule out medical problems.

Being Too Warm
Older dogs may become uncomfortable if their sleeping environment is too warm. Panting is a normal cooling mechanism, so excessive warmth can lead to nighttime panting and restlessness.
Heavy bedding, poor ventilation, or warm weather can contribute.
If your dog settles after moving to a comfortably cool area, temperature may have played a role. Panting that continues in a comfortable environment requires further consideration.

Gastrointestinal Discomfort
Nausea can cause panting, trembling, lip licking, drooling, swallowing, and restlessness. A senior dog with stomach or intestinal discomfort may have difficulty settling during the night.
Vomiting, diarrhea, reduced appetite, or changes in bowel movements may occur at the same time.
Older dogs with persistent digestive symptoms should be evaluated because gastrointestinal signs can occur with many different conditions.
Heart or Respiratory Problems
Panting while resting can sometimes be associated with heart or respiratory disease. Senior dogs may develop conditions that affect their ability to breathe comfortably or tolerate normal activity.
Coughing, reduced exercise tolerance, rapid breathing, weakness, or difficulty settling when lying down may accompany the nighttime panting.
Persistent panting at rest should not be dismissed as simply an age-related change, particularly when breathing appears abnormal.
Medication Effects
Some medications can alter a dog’s sleep, behavior, appetite, thirst, or breathing. A senior dog may become restless or pant more after starting or changing certain treatments.
If the nighttime symptoms began after a new medication or dose change, tell your veterinarian exactly what your dog is receiving.
Do not stop, increase, or decrease a prescribed medication without veterinary guidance.
Other Age-Related or Medical Conditions
Various health problems can cause panting, trembling, restlessness, or changes in sleep. Metabolic disorders, hormonal conditions, neurological disease, fever, and other illnesses may produce similar signs.
Because symptoms can overlap, it is difficult to determine the cause based on nighttime behavior alone.
A veterinary examination becomes particularly important when a previously settled senior dog suddenly begins panting and shaking every night.
When to Call or Visit the Vet
New or persistent nighttime panting and shaking in a senior dog should be discussed with a veterinarian, particularly when it interferes with sleep or is accompanied by other changes. Contact your veterinarian immediately if you notice:
Persistent panting while your dog is resting
Repeated or worsening shaking
Obvious pain, stiffness, or difficulty getting comfortable
Coughing or changes in breathing
Vomiting, diarrhea, or loss of appetite
Unusual confusion or major behavior changes
Difficulty standing or walking
Marked weakness, collapse, or severe breathing difficulty
Senior Dog Panting and Shaking at Night: Treatment
Veterinary treatment for a senior 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 senior dog panting and shaking at night may be experiencing pain, anxiety, cognitive changes, overheating, nausea, medication effects, or an underlying medical condition.
While some nighttime restlessness can occur with aging, persistent panting and trembling should not automatically be considered a normal part of getting older.
Pay attention to changes in mobility, sleep, appetite, breathing, digestion, and behavior.
These details can help identify whether your dog may be experiencing discomfort or illness.
If your senior dog continues panting and shaking at night, particularly while resting, arrange a veterinary examination.
Prompt attention can help identify the underlying problem and improve your dog’s comfort and nighttime rest.
