If your dog is shaking in a slow, rhythmic, or progressive way—almost resembling Parkinson’s disease in humans—it could indicate a chronic neurological or muscular issue. While dogs don’t get Parkinson’s exactly like humans do, they can develop similar movement disorders.
We outline the common causes of dog shaking like Parkinson’s, what you can do at home, and when to seek veterinary help.
Dog Shaking Like Parkinson’s — Why It Happens
Dogs may shake in a Parkinson’s-like manner due to degenerative nerve conditions, essential tremors, brain inflammation, or breed-specific disorders. These tremors are often consistent, worsen over time, and may affect posture, coordination, or limb control.
Common Causes of Dog Shaking Like Parkinson’s
Degenerative Myelopathy
Degenerative myelopathy is a progressive spinal cord disease seen in older dogs, especially German Shepherds.
It starts with hind limb weakness and may resemble Parkinson’s in its gradual onset and mobility decline.
Dogs often drag their paws, shake in the rear limbs, or struggle to stand.
There’s no cure, but physical therapy, supportive care, and lifestyle adjustments can help extend quality of life.

Essential Tremor Syndrome
This is a movement disorder that causes rhythmic shaking—often of the head or limbs.
Unlike seizures, dogs stay conscious and alert during tremors.
Tremors may occur when your dog is trying to move or maintain posture and may improve when they’re at rest.
Some breeds, like Dobermans or Weimaraners, are more prone to this condition.
Cerebellar Abiotrophy
This inherited neurological disorder affects the cerebellum, the part of the brain responsible for balance and coordination.
Affected dogs show intention tremors—shaking that worsens when they try to move or focus.
You might notice a wide-legged stance, wobbling, or difficulty turning.
There’s no cure, but many dogs adapt well with support and a stable environment.
Brain Inflammation or Tumors
Inflammation due to infection (encephalitis) or brain tumors can cause Parkinson’s-like symptoms.
Dogs may shake, lose coordination, develop head tilt, or have seizures.
Early signs can be subtle—such as personality changes or mild tremors.
Advanced imaging like MRI is usually needed for diagnosis.
Breed-Specific Conditions (e.g., Shaker Syndrome)
Some small or toy breeds like Maltese, Westies, and Poodles can develop generalized tremor syndrome.
This condition often appears suddenly and resembles Parkinson’s in its constant trembling.
Corticosteroid treatment is typically effective, and many dogs recover fully with care.
What to Do If Your Dog Is Shaking Like Parkinson’s
Start by documenting the frequency, duration, and triggers of the tremors.
Note if the shaking worsens with movement or is present at rest.
Keep your dog’s environment safe—avoid stairs or slippery surfaces.
Provide a calm, stress-free space and assist with mobility if needed.
Schedule a veterinary visit to rule out treatable causes and begin supportive care if the condition is progressive.
When to Call or Visit Your Vet
Seek veterinary evaluation if your dog:
Develops new or worsening tremors
Struggles with balance or mobility
Shows signs of confusion or behavioral change
Has seizures, stiffness, or abnormal posture
Belongs to a breed prone to neurological disorders
Early diagnosis can improve management options and your dog’s comfort.

Key Takeaway
If your dog shakes in a way that resembles Parkinson’s, don’t ignore it—it may point to a deeper neurological issue.
While some conditions can be managed, others are progressive and require lifestyle changes.
Partner with your vet for diagnosis, support, and a care plan tailored to your dog’s needs.
