Top 10 Signs Your Dog Might Be in Pain (And What to Do About It)

7. Trembling or Shaking

It’s normal for dogs to shiver when they’re cold, anxious, or overly excited. However, if your dog begins trembling or shaking without an obvious reason, it could be a sign of pain, stress, or even a serious medical issue.

Shaking is often your dog’s way of signaling that something inside doesn’t feel right. Unlike temporary shivers from excitement, pain-related trembling usually continues and is paired with other symptoms.

Common Causes of Trembling

1. Pain Response – Dogs may shake when arthritis, muscle strain, or injuries flare up.

• Nausea or Stomach Issues – Upset stomach, indigestion, or pancreatitis can trigger shaking.

• Poisoning or Toxic Reactions – Eating harmful foods (like chocolate or grapes) or chemicals can cause tremors.

• Neurological Disorders – Conditions like seizures or nervous system issues may begin with trembling.

• Stress or Fear – Loud noises, vet visits, or separation anxiety can also cause shaking.

When Trembling Is a Medical Emergency

Not all shaking is serious, but immediate vet care is needed if you notice:

• Shaking paired with vomiting, diarrhea, or drooling.

• Trembling after eating unusual foods or substances (possible poisoning).

• Shaking with weakness, collapse, or inability to stand.

• Constant trembling that doesn’t stop with comfort or rest.

• Visible abdominal pain or bloating, which can signal pancreatitis or bloat.

These situations can escalate quickly, so it’s best to treat them as urgent.

What You Can Do at Home

• Observe Closely – Take note of when shaking starts (after eating, after exercise, when touched).

• Check for Environmental Triggers – Remove anything stressful (loud noises, strangers, or cold drafts).

• Keep Your Dog Warm and Comfortable – Provide blankets if cold, or a quiet safe space if stressed.

• Avoid Home Remedies – Don’t give human medications; they can worsen the situation.

Veterinary Diagnosis and Treatment

Your vet may check for poisoning, organ problems, or pain through:

• Blood tests and urinalysis to rule out toxins or organ disease.

• Imaging (X-ray, ultrasound) if abdominal pain is suspected.

• Neurological exams if seizures or nervous system disorders are a concern.

• IV fluids, anti-nausea, or pain relief medications depending on the cause.
