If your dog trembles as if he’s nervous—even when there’s no obvious reason—it could mean more than just a case of the jitters. Shaking that mimics nervous behavior can stem from anxiety, medical issues, or emotional hypersensitivity.
We outline the common causes of dog shaking like nervous, what you can do at home, and when to seek veterinary help.
Dog Shaking Like Nervous — Why It Happens
Dogs may shake like they’re nervous due to fear, separation anxiety, phobias, chronic stress, or even underlying pain or illness. When trembling happens often or suddenly, it’s a sign that something needs closer investigation.
Common Causes of Dog Shaking Like Nervous
Anxiety or Emotional Stress
One of the most common reasons dogs shake nervously is anxiety.
Triggers include separation, loud noises, unfamiliar places, or even overstimulation.
You may also notice pacing, panting, yawning, or avoiding eye contact.
Behavior modification, desensitization training, and calming tools can help manage anxiety.
Generalized Tremor Syndrome (GTS)
Also known as “shaker syndrome,” this condition causes fine, full-body tremors that resemble nervous shaking.
It’s most often seen in small white breeds like Maltese or West Highland Terriers, but can affect any dog.
The tremors usually worsen with excitement but are not painful.
Steroid treatment often resolves or controls the symptoms.

Nausea or Digestive Discomfort
A nauseous dog may shake quietly and appear nervous or unsettled.
Common causes include dietary indiscretion, motion sickness, or gastrointestinal illness.
Look for signs like drooling, lip licking, or refusing food.
A vet can provide medication and guidance if nausea becomes persistent.
Past Trauma or Negative Experiences
Dogs with a history of abuse or neglect may shake nervously in response to subtle cues.
This fear-based behavior can take time to unravel and may require professional training support.
Creating a predictable, calm environment is essential for building trust.
Gradual desensitization can help reduce their reactivity over time.
Pain or Neurological Issues
Pain—especially internal or chronic pain—can manifest as nervous-like shaking.
Dogs may also tremble due to neurological disorders that affect coordination or sensory perception.
If your dog’s shaking is accompanied by stiffness, limping, or confusion, contact your vet promptly.

What to Do If Your Dog Is Shaking Like Nervous
Start by identifying patterns—does the shaking happen during certain times or events?
Speak calmly and avoid reinforcing the anxiety by coddling too much during episodes.
Provide a quiet, secure space for your dog to decompress.
Consider anxiety-reducing products like calming pheromone sprays, pressure wraps, or enrichment toys.
If the shaking becomes frequent, worsens, or is paired with other symptoms, consult your vet.
When to Call or Visit Your Vet
Call your veterinarian if your dog:
Shakes frequently with no clear trigger
Develops new symptoms like vomiting, lethargy, or stiffness
Has a history of trauma or high anxiety
Is a breed prone to tremor syndrome
Shakes even when calm and comfortable
A vet can rule out medical causes and help you develop a management plan.
