If your dog is shaking and restless at night, something is likely disrupting their sense of safety, comfort, or internal balance. These symptoms may reflect physical discomfort, anxiety, or an underlying health condition that becomes more noticeable in the quiet of nighttime.
We outline the common causes of dog shaking and restlessness at night, what you can do at home, and when to seek veterinary help.
Dog Shaking and Restless at Night — Why It Happens
Dogs may shake and become restless at night due to pain, anxiety, gastrointestinal distress, or age-related cognitive changes. Nighttime exacerbates these symptoms because there are fewer distractions, and discomfort is often harder for dogs to ignore when trying to sleep.
Common Causes of Dog Shaking and Restlessness at Night
Anxiety or Noise Sensitivity
Some dogs become anxious when the house is dark and quiet, especially if they’re used to being around people during the day.
Common triggers include separation anxiety, fireworks, storms, or unfamiliar nighttime sounds.
Shaking is often paired with pacing, panting, whining, or attempts to wake their owner.
Nighttime calming routines, white noise, or anxiety aids can help reduce symptoms.
Pain from Arthritis or Injury
Dogs with joint problems or undiagnosed injuries may struggle more at night when they lie still for long periods.
Shaking may reflect discomfort, while restlessness suggests they’re having trouble getting comfortable.
If your dog frequently changes position, groans, or avoids lying down, pain may be the cause.
A vet check and appropriate pain management are essential.

Digestive Upset or Hunger
Dogs experiencing bloating, gas, or indigestion may appear uncomfortable and unable to rest.
Shaking may accompany nausea, stomach rumbling, or licking of lips.
Similarly, hunger—especially in puppies or small breeds—can cause agitation and tremors from low blood sugar.
Feeding a small bedtime snack and ensuring regular meals may help resolve these symptoms.
Cognitive Dysfunction (Dog Dementia)
Older dogs may develop canine cognitive dysfunction, a condition similar to dementia in humans.
They may become confused at night, pacing or whining with no clear reason.
Shaking may result from anxiety or disorientation.
Other signs include house soiling, changes in sleep-wake cycles, and altered interactions with family members.
Vets can prescribe medications and supplements to ease these symptoms.
Hormonal or Metabolic Issues
Conditions like hypothyroidism, Addison’s disease, or diabetes can cause tremors and sleep disturbances.
These dogs may seem fine during the day but exhibit signs of instability or agitation at night.
Shaking, restlessness, changes in appetite or thirst, and urinary accidents can be clues.
Diagnostic blood work is required to confirm and treat these underlying causes.
What to Do If Your Dog Is Shaking and Restless at Night
Try to comfort your dog calmly—speak softly, pet them gently, and keep the lights low.
Provide a soft, warm bed in a quiet area. Use white noise or soft music to mask environmental sounds.
Make sure your dog isn’t hungry, in pain, or showing signs of gastrointestinal upset.
Maintain a consistent nighttime routine to signal that it’s time to settle down.
If symptoms persist, start keeping a journal of your dog’s nighttime behaviors to share with your vet.
When to Call or Visit Your Vet
Consult your veterinarian if your dog:
Shakes or paces for more than an hour at night
Shows additional signs like vomiting, panting, or crying
Appears disoriented or confused
Has disrupted sleep for multiple nights in a row
Shows any signs of physical pain or injury
Early intervention can prevent a manageable issue from becoming chronic or worsening overnight.
