Canine Shivering in Dogs: Causes, Diagnosis, and Treatment Guide

If your dog is trembling, shaking, or shivering, it's natural to feel concerned. Canine shivering is not a disease itself but a clinical sign — an involuntary, rhythmic muscle contraction that can stem from dozens of underlying causes ranging from harmless (cold, excitement, anxiety) to life-threatening (toxicity, hypoglycemia, neurological disease). According to the Merck Veterinary Manual, tremors and shivering episodes are among the most common neurological complaints seen in general veterinary practice, affecting dogs of all breeds and ages.

Because canine shivering can signal anything from a dropped body temperature to a seizure disorder, understanding the context — when it started, what else your dog is experiencing, and how long it lasts — is critical for determining whether you're dealing with a minor issue or a veterinary emergency.

What Is Canine Shivering in Dogs?

Canine shivering refers to involuntary, repetitive muscle contractions that cause visible trembling or shaking. These contractions are generated by the central nervous system and can involve the entire body or be localized to specific muscle groups (head, hindquarters, or limbs).

It's important to distinguish shivering from related but distinct conditions:

ConditionDescriptionKey Differentiator
Shivering/TremorRhythmic, involuntary muscle contractionsStops during sleep; may be episodic or constant
SeizureAbnormal electrical brain activityDog may lose consciousness, paddle legs, drool excessively; post-ictal confusion follows
Muscle FasciculationSmall, localized muscle twitchesVisible under the skin; often related to nerve damage or electrolyte imbalance
Steroid-Responsive Tremor Syndrome (SRTS)Immune-mediated cerebellar inflammationFull-body intention tremors; most common in small white breeds
Shaker SyndromeAnother name for SRTSSame as above — idiopathic cerebellar tremors

Canine shivering is remarkably common. Nearly every dog will shiver at some point due to environmental cold, fear, or excitement. However, persistent or unexplained shivering warrants veterinary evaluation, as it may indicate pain, metabolic disease, toxic exposure, or neurological dysfunction.

Symptoms Checklist: Recognizing Canine Shivering by Severity

Not all shivering is equal. Use this checklist to assess where your dog falls on the severity spectrum. If you observe any advanced symptoms, contact your veterinarian immediately.

Severity LevelSymptomsTypical Context
Early / MildOccasional whole-body trembling
Shivering that stops when warmed or comforted
Mild anxiety-related shaking (vet visits, thunderstorms)
Slight head bobbing during focused activity
Cold weather, stress, excitement, anticipation of food or walks
ModerateFrequent or prolonged shivering episodes (>10 minutes)
Localized tremors in legs or head
Reluctance to move or jump
Decreased appetite
Whimpering or signs of discomfort
Tremors that worsen with movement (intention tremors)
Pain (orthopedic or abdominal), early metabolic disease, mild toxicity, anxiety disorders
Advanced / EmergencyConstant, severe full-body tremors
Inability to stand or walk
Vomiting or diarrhea alongside tremors
Seizure-like episodes with loss of consciousness
Extreme lethargy or collapse
Dilated pupils, excessive drooling
Body temperature below 95°F (35°C) or above 104°F (40°C)
Toxic ingestion (chocolate, xylitol, permethrin), severe hypoglycemia, SRTS, distemper, heatstroke, organ failure

A key diagnostic clue: tremors that disappear during sleep typically point to a non-seizure cause, such as SRTS, anxiety, or pain. Seizures, by contrast, can occur during sleep and are usually followed by a disoriented post-ictal phase lasting minutes to hours.

Risk Factors: Which Dogs Are Most Prone to Shivering?

Breed Predisposition:

  • Small and toy breeds (Chihuahuas, Yorkshire Terriers, Pomeranians, Maltese) — prone to hypoglycemia-related shivering and generalized tremor syndrome
  • Small white breeds (West Highland White Terriers, Maltese, Bichon Frise) — overrepresented in Steroid-Responsive Tremor Syndrome (SRTS) cases
  • Large breeds (Weimaraners, Dalmatians, Samoyeds) — higher risk of degenerative myelopathy and certain metabolic disorders presenting with tremors
  • Brachycephalic breeds (English Bulldogs, Pugs) — may shiver due to respiratory distress or brachycephalic obstructive airway syndrome (BOAS)

Age:

  • Puppies under 6 months — higher hypoglycemia risk, incomplete vaccination status (distemper vulnerability)
  • Senior dogs over 8 years — increased risk of cognitive dysfunction, organ disease, and degenerative neurological conditions

Weight:

  • Underweight dogs (Body Condition Score 1-3/9) — less insulating body fat, higher susceptibility to cold-induced shivering and hypoglycemia
  • Overweight dogs (BCS 7-9/9) — increased joint pain that may manifest as trembling in the hindquarters

Environment:

  • Outdoor dogs in cold climates (below 45°F / 7°C)
  • Dogs exposed to pesticides, rodenticides, or toxic plants
  • Dogs in high-stress environments (frequent loud noises, separation anxiety triggers)

Genetics:

  • Dogs with a family history of idiopathic epilepsy or cerebellar abiotrophy
  • Certain inherited metabolic disorders (e.g., lysosomal storage diseases in specific breeds)

How Is Canine Shivering Diagnosed?

Because canine shivering is a symptom rather than a disease, your veterinarian will work through a systematic diagnostic process to identify the underlying cause. Here's what to expect during your visit, along with estimated costs based on 2026 veterinary pricing.

  1. Complete History and Physical Examination ($65–$120 office visit fee)
    Your vet will ask about onset, duration, triggers, and accompanying symptoms. They'll perform a full neurological exam — testing proprioception (paw placement), cranial nerve function, spinal reflexes, and gait analysis. Be prepared to describe: when shivering started, whether it stops during sleep, any recent diet changes, potential toxin exposure, and vaccination status.
  2. Blood Work and Urinalysis ($150–$350)
    A complete blood count (CBC), serum biochemistry panel, and urinalysis screen for metabolic causes: hypoglycemia, hypocalcemia, kidney or liver dysfunction, electrolyte imbalances, and infection markers. A thyroid panel ($80–$150 additional) may be recommended for older dogs to rule out hypothyroidism.
  3. Toxin Screening ($100–$250 if indicated)
    If toxicity is suspected, your vet may run specific tests for common canine toxins — ethylene glycol (antifreeze), permethrin (flea products meant for cats), metaldehyde (snail bait), or mycotoxins. Note: not all toxins have readily available screening tests, so history is critical.
  4. Advanced Imaging ($500–$2,500)
    If neurological disease is suspected — SRTS, cerebellar degeneration, brain tumor, or spinal cord disease — your vet may recommend an MRI or CT scan. These are typically performed at specialty centers and require general anesthesia ($200–$400 additional). A CT scan ranges from $800–$1,500; an MRI from $1,200–$2,500.
  5. Cerebrospinal Fluid (CSF) Analysis ($300–$600)
    If inflammatory or infectious neurological disease is suspected, a CSF tap (spinal tap) may be performed, usually alongside MRI. Elevated white blood cells or protein in the CSF can confirm inflammatory conditions like SRTS or infectious diseases like distemper.
  6. Specialist Referral (Neurology Consultation: $200–$400)
    Complex or undiagnosed cases may be referred to a board-certified veterinary neurologist (DACVIM-Neurology). These specialists can perform advanced testing including electroencephalography (EEG) or electromyography (EMG).

Total diagnostic cost range: $215 for a basic workup (office visit + blood work) to $3,500+ for comprehensive neurological investigation including MRI and CSF analysis.

Treatment Options: Medical, Surgical, and Supportive Care

Treatment for canine shivering depends entirely on the underlying cause. Below is a comparison of the most common diagnoses and their corresponding treatments.

Underlying CauseTreatment ApproachMedications/ProceduresSuccess Rate / Expected Outcome
HypoglycemiaImmediate glucose supplementation + dietary managementIV dextrose (emergency); frequent small meals with complex carbs; corn syrup on gums at homeExcellent if caught early; resolves within hours with glucose. Recurrent episodes require investigation for insulinoma or liver disease.
Steroid-Responsive Tremor Syndrome (SRTS)Immunosuppressive corticosteroid therapyPrednisone at 2–4 mg/kg/day initially, tapered over 4–6 monthsVery good to excellent — most dogs show improvement within 3–7 days. Full remission in 80–90% of cases. Some require long-term low-dose maintenance.
Toxicity (permethrin, chocolate, xylitol)Decontamination + supportive careInduced vomiting (if within 2 hours), activated charcoal, IV fluids, IV lipid emulsion therapy for permethrin, diazepam for seizure controlVaries by toxin and dose. Permethrin toxicity: >95% survival with treatment. Xylitol: good prognosis if treated before liver failure. Chocolate: excellent with prompt care.
Pain-Related ShiveringPain management + treatment of underlying conditionNSAIDs (carprofen, meloxicam), gabapentin, physical therapy, surgical intervention for IVDD or fracturesDepends on cause. Orthopedic pain: good with multimodal management. IVDD: 80–95% success with surgery for ambulatory dogs.
HypothermiaGradual rewarming + supportive careWarm blankets, warm IV fluids, forced-air warming devices (Bair Hugger). Target: 1–2°F per hour rewarmingGood if core temperature hasn't dropped below 90°F (32°C). Below that, cardiac arrhythmia risk increases significantly.
Idiopathic Head TremorsObservation — no specific treatment requiredNone proven effective; episodes self-limiting (typically 1–3 minutes). Distraction techniques may shorten episodes.Benign condition. Does not progress or affect quality of life. Episodes may decrease in frequency over time.
Degenerative MyelopathySupportive care + mobility managementNo cure. Physical therapy, mobility carts ($300–$600), toe protectors, aminocaproic acid (off-label, limited evidence)Progressive and ultimately fatal. Median survival: 6–12 months from onset of non-ambulatory status. Euthanasia typically elected when quality of life declines.
Anxiety/Fear-Related ShiveringBehavioral modification + anxiolytic medicationDesensitization and counter-conditioning (force-free methods only); trazodone (2–5 mg/kg), fluoxetine (1–2 mg/kg), or clomipramine for long-term managementGood with consistent behavioral protocol + medication. Improvement typically seen within 4–8 weeks of combined therapy.

Important: Never administer human medications (ibuprofen, acetaminophen, aspirin) to your dog without explicit veterinary direction. These can cause fatal toxicity. Always consult your veterinarian before starting, stopping, or adjusting any medication.

Prognosis by Stage and Severity

The prognosis for canine shivering varies enormously depending on the underlying diagnosis. Here's a realistic breakdown:

ConditionMild / Early StageModerate StageAdvanced / Severe Stage
HypoglycemiaFull recovery within hours with glucoseGood with dietary management; investigate underlying causeSeizures and coma possible; brain damage if glucose remains low >30 minutes
SRTS (Shaker Syndrome)Excellent — tremors resolve in days with steroidsVery good — most dogs return to normal within 1–2 weeksGood with aggressive immunosuppression; rare non-responders may need alternative drugs (cytosine arabinoside)
ToxicityFull recovery expected with prompt treatmentGood — 24–72 hour hospitalization typically requiredGuarded to poor if organ damage has occurred (xylitol-induced liver failure, antifreeze-induced kidney failure)
Pain-RelatedGood — resolves when pain is managedGood to fair — depends on underlying orthopedic or spinal conditionFair to guarded — surgical conditions like IVDD have 80–95% success if dog is still ambulatory; poor if deep pain sensation is lost >48 hours
Degenerative MyelopathyFair — progressive but slow; months of functional life remainPoor — significant mobility loss; cart or sling neededGrave — non-ambulatory, incontinent; euthanasia typically elected
Distemper (neurological phase)Guarded — some dogs recover with supportive carePoor — progressive neurological deterioration commonGrave — mortality rate 50–90% once neurological signs appear; survivors often have permanent myoclonus (muscle twitching)

Home Care and Daily Management

Once your veterinarian has diagnosed the cause of your dog's shivering and prescribed a treatment plan, consistent home management is essential for recovery and quality of life.

For Dogs with SRTS (on Steroid Therapy)

  • Administer prednisone exactly as prescribed. Never skip doses or stop abruptly — this can cause an Addisonian crisis (adrenal insufficiency).
  • Expect increased thirst and urination. Provide constant access to fresh water and more frequent potty breaks.
  • Monitor appetite — steroids increase hunger. Feed measured meals to prevent obesity.
  • Watch for panting, restlessness, or GI upset (vomiting, dark stools). Report these to your vet — they may indicate the dose needs adjustment.
  • Keep a tremor diary: note date, time, duration, and intensity of any residual tremor episodes to share at recheck appointments.

For Dogs with Anxiety-Related Shivering

  • Create a designated safe space — a crate with a blanket, a quiet room, or a covered bed — where your dog can retreat during stressors.
  • Use white noise machines or calming music (classical or specifically designed canine relaxation tracks) during known triggers like thunderstorms or fireworks.
  • Consider a pressure-wrap garment (e.g., Thundershirt) for situational anxiety — studies show modest benefit for noise phobia in some dogs.
  • Practice desensitization and counter-conditioning using positive reinforcement. Pair low-intensity versions of the trigger (recorded thunder at low volume) with high-value treats. Never use punishment, shock collars, or aversive methods — these increase anxiety and worsen trembling.

For Small Breeds Prone to Hypoglycemia

  • Feed 3–4 small meals per day rather than one or two large meals.
  • Keep a small bottle of corn syrup or Nutri-Cal (a veterinary glucose gel, ~$8–$12 per tube) on hand. If shivering begins, rub a small amount on the gums and offer food within 10 minutes.
  • Avoid fasting periods longer than 8 hours for toy breeds under 10 lb (4.5 kg).

For Dogs with Pain-Related Trembling

  • Provide orthopedic bedding — memory foam or elevated cot-style beds reduce joint pressure.
  • Use non-slip rugs on hard flooring to prevent struggling and further strain.
  • Follow your vet's physical therapy or rehabilitation protocol. Underwater treadmill sessions ($50–$85 each) can strengthen muscles without joint impact.
  • Administer pain medications on schedule — don't wait for visible trembling to give the next dose.

How Much Does Canine Shivering Treatment Cost?

Because canine shivering has so many potential causes, treatment costs range from minimal to substantial. Here's a realistic breakdown based on 2026 US veterinary pricing:

ScenarioInitial Diagnosis CostTreatment CostOngoing / Annual Cost
Benign (cold, excitement, mild anxiety)$65–$120 office visit$0–$50 (coat, calming aids)$0–$150/year
Hypoglycemia (toy breed puppy)$150–$350 (exam + blood work)$200–$800 emergency visit if severe$100–$300/year (dietary management, Nutri-Cal)
SRTS (Steroid-Responsive Tremor Syndrome)$500–$2,500 (MRI + CSF tap at specialty center)$50–$200 (prednisone + rechecks over 6 months)$100–$400/year if long-term low-dose maintenance needed
Toxicity (emergency)$200–$500 (emergency exam + blood work + toxin screen)$1,000–$5,000+ (hospitalization, IV fluids, lipid emulsion, monitoring)$0 if full recovery; $200–$1,000+ if organ damage requires ongoing care
Pain-Related (IVDD surgery)$800–$2,500 (MRI + neurology consult)$3,000–$8,000 (hemilaminectomy surgery + hospitalization)$500–$1,500/year (medications, physical therapy, rechecks)
Anxiety Disorder (chronic)$150–$400 (exam + behavioral assessment)$30–$80/month (trazodone or fluoxetine)$400–$1,200/year (medication + behaviorist sessions at $100–$200 each)
Worst-Case (advanced neurological disease requiring MRI, surgery, long-term care)$2,000–$4,000$5,000–$15,000+$2,000–$5,000+/year

Budget tip: Pet insurance can significantly offset these costs. Most comprehensive plans (e.g., Trupanion, Healthy Paws, Lemonade) cover diagnostic imaging, specialist referrals, and surgery. Policies typically cost $30–$80/month for dogs under 5 years old and reimburse 70–90% of eligible costs after deductible. Pre-existing conditions are universally excluded, so enrolling before symptoms appear is critical.

Prevention Strategies

While not all causes of canine shivering are preventable, several strategies reduce risk for the most common triggers:

  • Cold weather protection: Dress short-coated and small breeds in insulated coats when temperatures drop below 45°F (7°C). Limit outdoor exposure to 10–15 minutes in sub-freezing weather. Indoor ambient temperature should stay above 65°F (18°C) for toy breeds and puppies.
  • Toxin prevention: Store all medications, cleaning products, antifreeze, and rodenticides in locked cabinets. Never use dog-toxic flea products (permethrin-based cat products are a leading cause of tremor-related emergency visits). Check the ASPCA Animal Poison Control database for toxic substance lists. If your dog ingests something unknown, call ASPCA Animal Poison Control at (888) 426-4435 (24/7, consultation fee applies) or the Pet Poison Helpline at (855) 764-7661.
  • Vaccination: Keep your dog current on core vaccines — particularly the DHPP (distemper, hepatitis, parainfluenza, parvovirus) vaccine. Canine distemper is a leading infectious cause of tremors and seizures, and there is no cure once neurological signs appear.
  • Hypoglycemia prevention in toy breeds: Feed frequent small meals, avoid prolonged fasting, and monitor puppies closely during growth spurts and stressful transitions (new home, travel).
  • Stress reduction: Maintain predictable routines, provide adequate mental and physical enrichment, and address anxiety early with positive-reinforcement training before it escalates to chronic stress-related trembling.

When to See the Vet: Emergency Red Flags

Seek immediate veterinary care (emergency clinic or your vet's urgent line) if your dog's shivering is accompanied by any of the following:

  • Tremors lasting more than 30 minutes without stopping
  • Inability to stand, walk, or bear weight on limbs
  • Vomiting, diarrhea, or drooling alongside tremors
  • Known or suspected ingestion of a toxic substance
  • Seizure activity — stiffening, paddling, loss of consciousness
  • Body temperature below 95°F (35°C) or above 104°F (40°C) — use a rectal thermometer if you have one
  • Pale or blue-tinged gums (indicates poor circulation or oxygen deprivation)
  • Extreme lethargy, unresponsiveness, or collapse
  • Shivering in an unvaccinated puppy (distemper risk)
  • Sudden onset of tremors in a previously healthy dog with no obvious environmental cause

If you suspect poisoning, call ASPCA Animal Poison Control at (888) 426-4435 immediately. Do not induce vomiting unless specifically instructed by a veterinary professional — some substances cause more damage coming back up.

For non-emergency shivering — mild, brief episodes that resolve on their own and don't recur frequently — schedule a routine veterinary appointment within 1–2 weeks to discuss. Bring a video of the shivering episode if possible; this is one of the most valuable diagnostic tools you can provide.

Frequently Asked Questions

What is canine shivering and when should I worry?

Canine shivering is involuntary muscle trembling that can result from cold, stress, pain, metabolic disease, toxicity, or neurological conditions. Occasional, brief shivering in response to cold or excitement is normal. You should worry — and contact your vet — if shivering is persistent, worsening, accompanied by other symptoms (vomiting, lethargy, weakness), or occurs in an unvaccinated puppy or elderly dog.

Which breeds are most prone to shivering?

Small and toy breeds (Chihuahuas, Yorkshire Terriers, Pomeranians) are most prone to shivering due to their high surface-area-to-volume ratio (they lose heat quickly) and susceptibility to hypoglycemia. Small white breeds (Maltese, West Highland White Terriers) are overrepresented in Steroid-Responsive Tremor Syndrome. However, any breed can develop shivering from pain, toxicity, or neurological disease.

How is canine shivering diagnosed?

Your vet will start with a thorough history and neurological exam, followed by blood work (CBC, chemistry, urinalysis) to rule out metabolic causes. If neurological disease is suspected, advanced imaging (MRI or CT) and cerebrospinal fluid analysis may be recommended. Total diagnostic costs range from $215 for basic screening to $3,500+ for comprehensive neurological workups.

Can canine shivering be cured?

It depends on the cause. Hypoglycemia, hypothermia, toxicity, and SRTS are all highly treatable, with many dogs making full recoveries. Anxiety-related shivering can be managed effectively with medication and behavioral modification. Degenerative conditions like degenerative myelopathy cannot be cured but can be managed for quality of life. Idiopathic head tremors are benign and require no treatment.

How much does treatment for canine shivering cost?

Costs range from $0 (benign shivering requiring only environmental adjustments) to $15,000+ (complex neurological cases requiring MRI, surgery, and long-term care). The most common scenarios — basic diagnostic workup and medication — typically fall in the $200–$1,000 range. Pet insurance can reimburse 70–90% of eligible costs.

What is the life expectancy of a dog with shivering-related disease?

Life expectancy depends entirely on the underlying diagnosis. Dogs with SRTS, hypoglycemia, anxiety, or idiopathic tremors have normal life expectancies with proper management. Dogs with degenerative myelopathy typically survive 6–18 months from diagnosis. Dogs with distemper involving neurological signs have a guarded prognosis, with mortality rates of 50–90%. Dogs treated promptly for toxicity generally have excellent long-term survival.

Should I wrap my shivering dog in blankets?

If the shivering is caused by cold, yes — wrapping your dog in warm (not hot) blankets and providing a heating pad set on low (with a towel barrier to prevent burns) can help. However, if your dog is shivering due to pain, anxiety, or a neurological condition, blankets won't address the cause. Check your dog's rectal temperature: if it's below 99°F (37.2°C), warming is appropriate. If it's normal or elevated, seek veterinary evaluation for other causes.

Can I give my dog Benadryl for shivering?

Diphenhydramine (Benadryl) is sometimes used for mild anxiety or allergic reactions in dogs at a dose of 1 mg per pound of body weight, but it is not an appropriate treatment for unexplained shivering. Shivering can indicate serious conditions that Benadryl will not address. Always consult your veterinarian before giving any over-the-counter medication to your dog — incorrect dosing or misdiagnosis can delay critical treatment.
