🐶 1. They’re Cold
Just like humans, dogs can shiver when they’re cold — especially small breeds, short-haired dogs, puppies, and seniors.
What to do: Provide a warm blanket, sweater, or bring them indoors.
🧠 2. Excitement or Happiness
Many dogs shake when they’re really excited — like when you come home or it’s time for a walk. This is normal and usually stops once they calm down.
What to do: Let them burn off the energy with play.
😨 3. Fear or Anxiety
Loud noises, new environments, or stressful events (like thunderstorms or fireworks) can cause trembling.
What to do: Offer comfort, create a safe space, and consider calming aids if needed.
🩺 4. Pain or Injury
Shaking can be a reaction to pain — whether from arthritis, an injury, or internal discomfort.
What to do: If shaking is accompanied by whining, limping, or behavior changes, see a vet promptly.
🍫 5. Toxin or Poison Exposure
Certain foods and chemicals (like chocolate, xylitol, or pesticides) can cause shaking, seizures, or collapse.
What to do: Treat as an emergency — call your vet or pet poison helpline immediately.
🦠 6. Illness or Medical Conditions
Conditions like distemper, kidney disease, or neurological issues may include shaking as a symptom.
What to do: Get a veterinary checkup to rule out serious causes.
🩸 7. Low Blood Sugar (Hypoglycemia)
Common in small breeds and puppies, low blood sugar can cause weakness, shaking, or collapse.
What to do: Offer a small snack and see a vet if symptoms persist.
🧬 8. Age-Related Tremors
Senior dogs may develop harmless tremors in their legs or head.
What to do: Have your vet confirm it’s not linked to illness, then monitor over time.

Shaking with vomiting or diarrhea

📌 Final Thoughts
So, why is your dog shaking?
It might be something as simple as excitement or as serious as illness. The key is to watch for other symptoms, know your dog’s normal behavior, and act quickly if something seems off.
Your pup can’t tell you what’s wrong — but by staying alert, you can make sure they get the care they need.
