Why Is My Dog Shaking? Top 10 Causes, Fixes & Vet Tips
If your dog suddenly starts trembling, your first thought might be — “Why is my dog shaking?” Seeing your beloved companion quiver can be both confusing and alarming. Is it fear? Cold? Pain? Or something more serious?
According to a 2024 American Kennel Club (AKC) study, nearly 30% of dog owners report observing shaking or tremors in their pets, with causes ranging from environmental stress to underlying medical conditions. Shaking can be perfectly normal in certain situations, but it can also be an early warning sign of illness, toxin exposure, or emotional distress.
Understanding Dog Shaking
Shaking in dogs is a natural body reflex — often a way to regulate temperature, release tension, or express emotion. For instance, dogs shake after swimming or baths to dry off, or after play to release pent-up adrenaline.
However, not all shaking is harmless. Abnormal tremors — especially those that are frequent, prolonged, or accompanied by behavioral changes — can indicate discomfort or illness.
| Type of Shaking | Possible Cause | What To Do |
| Quick post-bath shiver | Natural reaction to being wet | Towel dry and warm them up |
| Trembling with whining | Stress, anxiety, or pain | Check for stress triggers |
| Full-body shake at rest | Cold, fear, or illness | Adjust environment and observe |
| Head or leg tremor | Ear or neurological issue | Vet evaluation required |
The context and duration of shaking are vital clues. If your dog shakes briefly and returns to normal behavior, it’s likely harmless. Continuous or violent shaking, however, always warrants a closer look.
1. Cold Weather and Temperature Sensitivity
When temperatures drop, dogs — especially small or short-haired breeds — shake to generate body heat. Unlike their thick-coated counterparts, breeds like Chihuahuas, Greyhounds, and Italian Greyhounds lose warmth quickly.
Puppies and senior dogs are particularly vulnerable because they can’t regulate temperature efficiently. Even brief exposure to cold air or wet fur can trigger shivering.
Tips to Keep Your Dog Warm:
- Dress them in a well-fitted sweater or jacket during walks.
- Provide thick bedding and avoid placing dog beds on cold floors.
- Use heated mats or blankets in winter.
| Dog Type | Cold Sensitivity | Recommendation |
| Short-haired breeds | High | Warm clothing essential |
| Senior dogs | High | Heated bedding |
| Puppies | Moderate | Limit outdoor exposure |
| Double-coated breeds | Low | Occasional grooming |
2. Anxiety and Stress
Emotional distress is one of the most overlooked causes of shaking in dogs. Fear, separation anxiety, or overstimulation can make even confident dogs tremble.
Common triggers include loud noises (like fireworks or thunderstorms), unfamiliar environments, vet visits, or being left alone. When stressed, a dog’s body releases adrenaline, which manifests as trembling, panting, or pacing.
Signs of an Anxious Dog:
- Shaking or hiding
- Tail tucked between legs
- Excessive licking or yawning
- Refusing food or treats
How to Calm an Anxious Dog:
- Create a calm, quiet space.
- Use pheromone diffusers or calming music.
- Establish predictable routines.
- Practice slow desensitization to triggers.
A University of Helsinki study (2023) found that over 70% of dogs show at least one anxiety-related behavior, including trembling. Early training and emotional stability can make a huge difference.
3. Excitement or Anticipation
Sometimes shaking is simply your dog’s way of saying, “I’m so happy to see you!” Dogs may tremble when they anticipate food, playtime, or your return home.
This excitement releases adrenaline — the same hormone responsible for stress trembling — but in this case, it’s associated with positive energy.
Tip: To prevent overexcitement from turning into anxiety, teach calm greetings. Wait for your dog to sit or stay before engaging in play or giving rewards.
4. Pain or Injury
Persistent shaking can also indicate pain or physical discomfort. Dogs may shiver when suffering from muscle strains, joint pain, or internal issues.
Key Signs of Pain-Related Tremors:
- Limping or guarding a limb
- Whimpering when touched
- Reluctance to move or climb stairs
- Loss of appetite
Older dogs often shake due to arthritis or joint degeneration. Pain increases muscle tension, leading to trembling, especially after rest.
If your dog exhibits these signs, consult your vet for pain management options. Avoid giving human medications like ibuprofen, which are toxic to dogs.
5. Illness or Infection
Various diseases can cause shaking, either as a primary or secondary symptom. Infections such as canine distemper, ear infections, and kidney disease often lead to fever and tremors.
| Condition | Symptoms | Treatment |
| Canine distemper | Fever, nasal discharge, tremors | Vaccination, fluids, rest |
| Kidney disease | Shaking, fatigue, vomiting | Veterinary care & medication |
| Ear infection | Head shaking, scratching | Cleaning & antibiotics |
A dog shaking from illness may also appear lethargic, have glazed eyes, or show coordination issues. Early diagnosis significantly improves recovery chances.
6. Poisoning or Toxin Exposure
One of the most dangerous reasons for sudden shaking is poison ingestion. Substances like chocolate, caffeine, xylitol, antifreeze, and insecticides can cause neurological symptoms, including violent tremors.
Symptoms of Toxin Exposure:
- Drooling
- Vomiting
- Uncontrolled shaking
- Collapse or disorientation
If you suspect poisoning:
- Contact your vet or the ASPCA Animal Poison Control Center (888-426-4435) immediately.
- Don’t induce vomiting unless advised.
- Bring a sample or packaging of the substance for identification.
Prevention Tip: Store all chemicals and human foods securely out of reach.
7. Low Blood Sugar (Hypoglycemia)
Small and toy breeds like Pomeranians, Chihuahuas, and Maltese are prone to hypoglycemia. When blood sugar drops too low, their muscles lack the energy to function properly, causing trembling.
Common Symptoms:
- Weakness or confusion
- Trembling or collapse
- Glassy eyes
- Loss of coordination
Immediate Care:
Rub honey or corn syrup on your dog’s gums and visit the vet for glucose monitoring. For long-term prevention, provide small, frequent meals and avoid excessive exercise before feeding.
8. Seizures or Neurological Disorders
Neurological issues such as epilepsy or white shaker syndrome cause involuntary muscle movements resembling shaking. Unlike anxiety tremors, seizures are more severe and can involve loss of consciousness or body control.
What to Do During a Seizure:
- Keep your dog away from hard objects.
- Do not try to hold them down.
- Time the episode and inform your vet.
Diagnosis and Treatment:
Veterinarians may recommend blood tests, MRIs, or anticonvulsant medication like phenobarbital. With proper care, most dogs live comfortably despite chronic tremors.

9. Old Age and Muscle Weakness
Senior dogs often develop tremors due to muscle loss, arthritis, or neurological decline. Their legs may shake when standing or walking, particularly after rest.
How to Support an Aging Dog:
- Provide orthopedic bedding.
- Offer joint supplements (glucosamine, omega-3 fatty acids).
- Maintain moderate exercise to strengthen muscles.
- Keep them warm and avoid slippery floors.
Aging doesn’t have to mean suffering — a few adjustments in comfort and care go a long way.
10. Breed-Specific Tremors
Certain breeds inherit genetic tremor disorders, such as the White Shaker Syndrome, which primarily affects small white breeds like Maltese and West Highland Terriers.
| Breed | Tremor Risk | Treatment |
| Chihuahua | High | Anti-inflammatory meds |
| Maltese | Moderate | Corticosteroids |
| Jack Russell Terrier | High | Long-term management |
Though these tremors are usually benign, lifelong monitoring is recommended to ensure comfort and prevent secondary stress symptoms.
When to Visit the Vet
You should visit your vet if:
- The shaking is sudden and uncontrollable.
- It’s accompanied by vomiting, fever, or collapse.
- Your dog seems disoriented or in pain.
A veterinarian can perform physical exams, X-rays, or lab work to pinpoint the cause. Early diagnosis saves time, money, and — most importantly — your dog’s well-being.
Prevention and Care Tips
- Keep your dog’s environment calm and warm.
- Provide balanced nutrition rich in protein and vitamins.
- Schedule biannual vet checkups.
- Use positive reinforcement training to reduce anxiety.
- Avoid exposure to toxins and harmful foods.
Consistent love, structure, and care can significantly reduce stress-related shaking and promote overall wellness.
