Tremors in dogs are involuntary rhythmic muscle movements that can resemble shaking, shivering, or trembling. While they can be alarming to witness, it’s important to understand that tremors are not the same as seizures. In this comprehensive guide, we will explore the causes, symptoms, and treatment options for tremors in dogs.
What Are Tremors in Dogs?
Tremors are repetitive muscle movements that dogs cannot control. They can affect a single limb or involve the entire body. Tremors can be rapid or slow, vary in intensity from mild to incapacitating, and occur at rest or during movement. It’s crucial to differentiate tremors from seizures, as they have distinct characteristics.
The Difference Between Tremors and Seizures
Tremors and seizures may appear similar, but they have different underlying causes. Unlike seizures, which result from abnormal firing of neurons in the brain, tremors are not directly related to brain activity. Dogs experiencing tremors remain fully conscious, alert, mobile, responsive, and aware of their surroundings. Additionally, they do not exhibit autonomic signs such as salivation, urination, defecation, or vomiting during episodes.
Causes of Tremors in Dogs

Tremors in dogs can have various causes, ranging from simple emotions to complex illnesses. Identifying the underlying cause is crucial for effective treatment. Let’s explore the different categories of tremor causes in dogs.
Emotion-Related Tremors
Strong emotions can trigger tremors in some dogs. These emotions include:
- Joy
- Excitement
- Stress
- Fear
Discomfort-Related Tremors
Physical discomfort can also lead to tremors in dogs. Some examples of discomfort-related causes include:
- Cold
- Pain
- Nausea
- Fever
Illness-Related Tremors
Certain illnesses and diseases that affect the central nervous system can cause tremors in dogs. These include:
- Toxicity
- Metabolic Disorders
- Infectious Diseases
- Autoimmune Diseases
It’s essential to consult a veterinarian if your dog is experiencing tremors, as they can help identify the specific cause and recommend appropriate treatment.
Diagnosing Tremors in Dogs

Diagnosing the cause of tremors in dogs can be challenging due to the various diseases that can affect the central nervous system. A veterinarian will perform a thorough examination and conduct several tests to determine the underlying cause. These may include:
- Full physical examination
- Neurological examination
- Blood work, including CBC, chemistry panel, and urinalysis
- Chest X-rays
- Abdominal ultrasound
- MRI (magnetic resonance imaging)
- CSF (cerebrospinal fluid) analysis
- Infectious disease testing
In some cases, if all tests come back negative, the tremors may be classified as idiopathic, meaning the cause is unknown. Idiopathic tremor syndrome and idiopathic head tremors are two such diagnoses of exclusion.
Idiopathic Tremor Syndrome
Idiopathic tremor syndrome, also known as little white shaker syndrome, is an autoimmune condition that causes full-body tremors in dogs. While the exact cause is unknown, immune-mediated diseases are the most common forms of inflammation in the central nervous system in dogs. This syndrome is often observed in small white dog breeds such as Maltese, West Highland Terriers, and Poodles. Symptoms tend to improve when the dog is resting but worsen during activity or stress.
Treatment for Idiopathic Tremor Syndrome
While the exact cause of idiopathic tremor syndrome is unknown, it can be managed by suppressing the immune system with steroids. Most dogs show improvements within a week of treatment. The prognosis for dogs with idiopathic tremor syndrome is excellent, and most dogs experience a full resolution of tremors with long-term use of low doses of prednisone.
Idiopathic Head Tremors
Idiopathic head tremors are characterized by horizontal “no” gestures, vertical “yes” gestures, or rotational “bobble head” motions. These tremors typically occur in the head and are most commonly seen in young dogs and certain breeds such as Dobermans, Bulldogs, French Bulldogs, Boxers, and Labradors. Idiopathic head tremors occur at rest and do not respond to steroids.
Treatment for Idiopathic Head Tremors
There is currently no specific treatment for idiopathic head tremors. However, the condition usually resolves as the dog grows older. Interestingly, these tremors can be stopped in the moment by simply distracting the dog.

Treatment Options for Tremors in Dogs
The treatment for tremors in dogs depends on the underlying cause. In cases where the cause is a medication or toxin, discontinuing the substance may resolve the tremors. If the tremors are due to an injury or brain abnormality, medication or surgery may be recommended. However, in some cases, such as age-related tremors, treatment may focus on managing the symptoms rather than curing the condition.
It’s important to follow the guidance of a veterinarian when determining the appropriate treatment for your dog‘s tremors. They will consider the specific cause, severity of symptoms, and potential side effects of medications.
Supporting Dogs with Tremors
If your dog is experiencing tremors, there are steps you can take to support their well-being:
- Ensure a safe environment: Remove any hazards that could potentially harm your dog during episodes of tremors.
- Provide comfort: Create a comfortable and calm space for your dog to rest during and after tremor episodes.
- Maintain a regular routine: Establish a consistent daily routine to help reduce stress and anxiety, which can contribute to tremors.
- Regular exercise: Engage your dog in regular, low-impact exercise to promote overall health and well-being. Consult with your veterinarian regarding appropriate exercise for your dog’s specific condition.
- Monitor diet: Ensure your dog is on a balanced and nutritious diet to support their overall health.
- Regular veterinary check-ups: Schedule regular check-ups with your veterinarian to monitor your dog’s condition and adjust treatment if necessary.
Remember, each dog’s situation is unique, so it’s crucial to work closely with your veterinarian to develop a tailored plan to manage your dog’s tremors effectively.
A puppy’s head trembles
If a puppy is experiencing tremors or shaking in its head, it can be concerning and may have various causes. It’s crucial to seek veterinary advice promptly to identify the underlying issue. Some potential causes and treatments may include:
- Hypoglycemia: Low blood sugar can cause trembling in puppies. Feeding them small, frequent meals and ensuring they have a balanced diet can help. In severe cases, a vet might recommend glucose supplementation.
- Infections or diseases: Various infections or illnesses, such as distemper, can lead to neurological issues. Treatment often involves supportive care and medications to manage symptoms.
