Muscle Tremors in Dogs: What Can Cause These

If your dog experiences muscle tremors, it’s natural to feel concerned and want to understand what’s happening. Muscle tremors in dogs can range from mild to severe and often leave pet owners puzzled. While they may occasionally stem from something harmless, tremors can also signal underlying health issues that warrant professional attention.

What Are Muscle Tremors in Dogs?

Muscle tremors refer to involuntary rhythmic movements or shaking of a dog’s muscles. They can occur in a specific part of the body, such as the legs, or involve the entire body. Tremors might be subtle, with only slight quivering, or more pronounced, causing visible shaking. Unlike seizures, muscle tremors usually don’t affect a dog’s consciousness. These movements can have various causes, some benign and others more serious. Tremors may appear suddenly or develop gradually over time. Observing the frequency, duration, and triggers for your dog’s tremors can provide valuable information to your veterinarian.

Causes of Muscle Tremors in Dogs

Muscle tremors in dogs can result from several factors, ranging from environmental influences to underlying health conditions. Below are some of the most common causes.

Toxicity or Poisoning

Exposure to toxic substances is one of the leading causes of muscle tremors in dogs. Household items like chocolate, caffeine, rodenticides, or medications can cause toxicity, leading to uncontrollable muscle movements. Certain plants, such as lilies or sago palms, can also trigger this reaction. Signs of toxicity often include vomiting, drooling, lethargy, and tremors. If you suspect your dog has ingested something toxic, contact a veterinarian immediately.

Hypoglycemia

Low blood sugar, or hypoglycemia, is especially common in small breeds, puppies, and dogs with diabetes. Hypoglycemia can occur when a dog hasn’t eaten for an extended period, engages in intense physical activity, or has an underlying metabolic disorder. Dogs experiencing hypoglycemia may show symptoms such as weakness, confusion, tremors, or even fainting. Regular feeding schedules and proper nutrition are essential for managing this condition.

Neurological Disorders

Disorders like cerebellar hypoplasia, degenerative myelopathy, or trauma to the brain or spinal cord may lead to involuntary muscle movements. Neurological tremors often appear alongside other symptoms such as difficulty walking, uncoordinated movements, or head tilting. A thorough neurological examination and diagnostic tests are needed to pinpoint the cause.

Muscle Strain or Injury

Injuries to the muscles, whether due to overexertion, a fall, or a direct impact, can result in localized tremors. When a muscle is strained or inflamed, it may contract involuntarily, causing trembling. Look for other signs of injury, such as limping, swelling, or tenderness in the affected area. If your dog seems uncomfortable or avoids using a specific limb, consult your veterinarian.

Distemper in Dogs

Canine distemper is a viral infection that can lead to muscle tremors. It primarily affects unvaccinated dogs and often begins with symptoms like fever, coughing, nasal discharge, and lethargy. As the condition progresses, it can cause neurological symptoms, including tremors or seizures. Distemper is a severe disease that requires immediate medical intervention. Preventive vaccinations are the best way to protect your dog from this condition.

Old Age and Tremor Syndrome

Older dogs, particularly small breeds, may develop a condition known as idiopathic tremor syndrome. The exact cause is unknown, but it typically presents as rhythmic shaking of the head or body. These tremors are generally harmless but can be unsettling to witness. Your veterinarian can rule out other potential causes to determine if this condition is the culprit.

Recognizing When Muscle Tremors Are a Medical Emergency

While some tremors are benign, others indicate serious health concerns that require immediate attention. Below are signs that your dog’s tremors may need urgent veterinary care:

• Sudden onset of tremors after exposure to toxins or new environments
• Accompanying symptoms such as vomiting, diarrhea, or difficulty breathing
• Persistent or worsening tremors
• Loss of coordination, consciousness, or responsiveness

If your dog displays any of these signs, call Buffalo Grove Animal Hospital at (847) 394-1128 or visit your nearest emergency veterinary clinic.

Diagnosing the Cause of Muscle Tremors

Your veterinarian will perform a comprehensive evaluation to identify the underlying cause of your dog’s tremors. This process typically includes:

• A detailed medical history, including diet, activity, and potential exposure to toxins
• A physical exam to assess muscle tone, coordination, and pain levels
• Blood tests to evaluate organ function, glucose levels, and toxin exposure
• Advanced diagnostics for neurological conditions

Treatment Options for Muscle Tremors

Treatment for muscle tremors depends on the underlying cause.

• In cases of toxicity, immediate intervention may involve inducing vomiting or administering activated charcoal to limit absorption. Intravenous fluids and medications may be used to stabilize your dog.
• For tremors caused by hypoglycemia, providing a quick source of glucose, such as a small amount of honey or corn syrup, can help raise blood sugar levels temporarily.
• Chronic conditions like neurological disorders often require long-term management with medications or physical therapy.
• In some cases, lifestyle adjustments, such as changes in diet or exercise routines, can reduce the frequency and severity of tremors. Your veterinarian will guide you through the best course of action.

Supporting Your Dog Through Muscle Tremors

Caring for a dog with muscle tremors involves patience and observation. Monitor your dog for changes in their behavior, diet, or physical activity. Create a calm environment, free from loud noises or sudden disturbances, to reduce stress levels. Keep a record of tremor episodes, including their frequency, duration, and triggers. This information can be invaluable for your veterinarian in diagnosing and managing the condition.
