If your dog is shaking and seems unsteady on their feet, it’s a cause for concern. These symptoms may indicate a neurological issue, vestibular disorder, toxin exposure, or other serious health condition affecting their balance and coordination.
We outline the common causes of dog shaking and unbalanced movement, what you can do at home, and when to seek veterinary help.
Why Is My Dog Shaking and Unbalanced — Why It Happens
Dogs may shake and appear unbalanced when their nervous system, inner ear, or muscles are compromised due to illness, injury, or toxicity. These symptoms often signal a disruption in the body’s ability to maintain normal posture, equilibrium, or nerve control, and they should never be ignored.
Common Causes of Dog Shaking and Unbalanced Behavior
Vestibular Disease
Canine vestibular syndrome is one of the most common causes of balance problems in dogs.
It affects the inner ear and brain structures responsible for balance, resulting in sudden loss of coordination, head tilt, rapid eye movements (nystagmus), and shaking.
Dogs may fall over, circle, or refuse to stand.
While it can be idiopathic (no known cause), it may also stem from inner ear infections, tumors, or inflammation.
Most dogs improve with supportive care, but immediate vet evaluation is needed to rule out serious causes.
Neurological Disorders
Seizure activity, brain inflammation (encephalitis), spinal injuries, or tumors can interfere with normal movement and behavior.
Trembling may accompany confusion, pacing, collapse, or muscle weakness.
Dogs may drag limbs, walk in circles, or show abnormal eye movement.
Neurological conditions often require imaging (MRI or CT scan) and specialized treatment.

Toxin Exposure
Exposure to toxins like chocolate, xylitol, moldy food, antifreeze, or rodenticides can affect both the nervous and muscular systems.
Affected dogs may shake, stagger, drool, vomit, or collapse.
Symptoms can progress rapidly, making early intervention critical.
Emergency veterinary treatment, often including hospitalization, may be lifesaving.
Low Blood Sugar (Hypoglycemia)
Especially in small breeds or puppies, a sudden drop in blood sugar can cause tremors and balance loss.
This can happen due to fasting, illness, or diabetes.
Other signs include disorientation, glassy eyes, collapse, or seizures.
Quick intervention with a glucose source and a vet visit can stabilize the situation.
Stroke or Brain Event
While rarer in dogs than humans, strokes can cause sudden onset of uncoordinated walking, head tilt, and tremors.
Affected dogs may seem dazed, weak on one side, or have difficulty standing.
Some strokes improve over time with supportive care, while others may need more aggressive management.
A thorough neurological workup is essential to confirm a diagnosis.
What to Do If Your Dog Is Shaking and Unbalanced
Keep your dog calm and prevent them from falling or hurting themselves—use towels or soft bedding to cushion their space.
Do not force movement, and avoid stairs or slippery floors.
Take a video of the symptoms to show your vet, especially if they come and go.
Avoid giving food, treats, or medication until your vet gives clearance.
If the symptoms are sudden or worsening, go to the emergency vet.
When to Call or Visit Your Vet
Get urgent veterinary help if your dog:
Cannot stand or repeatedly falls
Has a head tilt, rapid eye movements, or appears disoriented
Shows signs of poisoning or seizure
Suddenly collapses, vomits, or loses bladder/bowel control
Appears confused or unresponsive
Early intervention is key to treating the cause and improving your dog’s prognosis.
