# Why Is My Dog Shaking?


## Key Takeaways

- Canine shaking can stem from diverse etiologies including behavioral stressors (fear, anxiety), physiological responses to cold, or pain from musculoskeletal or visceral sources.
- Toxin ingestion is a critical differential diagnosis for tremors and seizures, necessitating immediate veterinary intervention to identify and manage the specific toxicant.
- Systemic illness, often accompanied by fever, can manifest as generalized shaking and lethargy, requiring diagnostic workup to determine the underlying infectious or inflammatory process.
- Emergency veterinary assessment is indicated for shaking accompanied by respiratory distress, collapse, seizures, severe gastrointestinal signs (hematemesis, melena, severe diarrhea), or signs of acute abdominal pain.
- Diagnostic approaches by veterinarians may include physical examination, neurological assessment, bloodwork (CBC, chemistry panel), urinalysis, fecal flotation, and advanced imaging (radiographs, ultrasound) to elucidate the cause.
- Proactive risk mitigation involves securing household toxins, providing adequate thermal insulation for susceptible breeds, and prompt veterinary consultation for persistent or severe tremors.

**Shaking or trembling in a dog can be mild or serious depending on the pattern, timing, and other signs. It may involve local irritation, discomfort, stress, injury, stomach upset, skin changes, or another medical problem. Call your veterinarian when signs are persistent, severe, or worsening.**

## What symptoms or causes should I watch for?

- **Fear or stress:** Noise, travel, or unfamiliar places can trigger shaking.
- **Pain:** Painful joints, belly pain, or injury may cause trembling.
- **Cold exposure:** Small and short-haired dogs chill more easily.
- **Toxin exposure:** Some toxins can cause tremors or seizures.
- **Fever or illness:** Sick dogs may shake and act withdrawn.

## What can I safely do at home right now?

- **Keep your pet calm:** Use a quiet room and limit rough activity until you know what is happening.
- **Check the basics:** Look for appetite changes, water intake, bathroom habits, breathing, pain, and energy level.
- **Remove obvious risks:** Pick up unsafe food, plants, medication, trash, string, toys, or chemicals.
- **Record details:** Write down when it started, how often it happens, and what changed recently.
- **Call your vet:** A dog owner should ask for guidance if the sign continues or the pet seems unwell.

## When is this an emergency?

Go to an emergency veterinary clinic now if you notice:

- Trouble breathing, collapse, seizures, or severe weakness.
- Repeated vomiting, severe diarrhea, blood, or a swollen belly.
- Obvious pain, inability to walk normally, or crying when touched.
- Not eating, not drinking, or not urinating normally.
- Any rapidly worsening sign, especially in a puppy, kitten, senior pet, or chronically ill pet.

## What will my veterinarian check?

Your veterinarian will use the history and physical exam to narrow the cause. They may recommend lab work, urine testing, stool testing, imaging, skin or ear tests, or other diagnostics based on the sign.

## How can I reduce the risk next time?

Keep toxins secured, protect from extreme cold, and seek care quickly for shaking with other illness signs.
