If your dog is shaking or trembling, it can be concerning—especially if it seems to come on suddenly. The good news is that not all shaking is serious. However, in some cases, it can be a sign of pain, illness, or a more urgent medical condition.

At Huntington Beach Pet Hospital, we frequently evaluate dogs for shaking to determine whether the cause is mild, behavioral, or something that requires medical attention.

If your dog is shaking and you’re unsure what to do, call Huntington Beach Pet Hospital at (714) 962-3639 for guidance.

Common Reasons Dogs Shake or Tremble

Dogs may shake for a variety of reasons, including:

  • Pain or discomfort
  • Anxiety or stress
  • Cold temperature
  • Gastrointestinal upset
  • Neurological conditions
  • Toxin exposure

Some causes are mild and temporary, while others require prompt veterinary care.

Real Examples of Dogs Shaking

At Huntington Beach Pet Hospital, we frequently evaluate dogs for shaking, and the cause is not always obvious at first. Some recent examples include:

  • A Schnauzer with pancreatitis
    A dog presented for repeated vomiting and noticeable shaking. On examination, the abdomen was very painful, and diagnostics confirmed pancreatitis. The shaking was a result of significant abdominal pain. With appropriate treatment, including medications and supportive care, the dog improved.
  • A Terrier with anxiety from loud construction noise
    A dog presented for intermittent shaking that was most noticeable at home. After discussing the history, we found that nearby construction was causing significant noise and stress. This case was determined to be anxiety-related, and we were able to help guide management to reduce stress and improve comfort.
  • A West Highland White Terrier (Westie) diagnosed with Addison’s disease
    A dog presented with shaking, lethargy, and general weakness. Further evaluation and diagnostic testing led to a diagnosis of Addison’s disease, a condition where the adrenal glands do not produce adequate steroid hormones. With appropriate treatment and long-term management, the dog improved significantly.

These examples highlight how shaking can be caused by a wide range of issues—from anxiety to pain to more serious medical conditions.

Shaking Due to Pain (Very Common)

One of the most common medical causes of shaking is pain.

Dogs may shake even when there is no obvious injury. You may also notice:

  • Restlessness
  • Hiding behavior
  • Decreased appetite
  • Sensitivity when touched

Pain-related shaking should always be evaluated, as dogs often hide discomfort until it becomes more severe.

When Dog Shaking Is More Serious

You should seek veterinary care right away if your dog is shaking and also has:

  • Vomiting or diarrhea
  • Lethargy or weakness
  • Difficulty walking
  • Signs of pain
  • Collapse or disorientation

These symptoms may indicate a more serious condition that requires urgent care or same-day evaluation.

If your dog is showing any of these signs, call Huntington Beach Pet Hospital at (714) 962-3639 so we can help determine the next step.

When Shaking May Be Normal

In some cases, mild shaking can be normal.

This may occur when:

  • Your dog is excited or anxious
  • Your dog is cold
  • The shaking is brief and resolves quickly

However, repeated or unexplained shaking should always be taken seriously.

Why Early Evaluation Matters

Shaking can sometimes be an early sign of:

  • Illness
  • Pain
  • Toxic exposure

Many serious conditions start with subtle symptoms. Early evaluation often leads to simpler treatment and better outcomes.

If your dog continues to shake or you’re unsure what’s causing it, it’s always safest to call and discuss your pet’s symptoms.

FAQ

Is shaking always serious?
Not always. Some causes are mild, such as anxiety or cold. However, persistent or unexplained shaking should be evaluated.

Can anxiety cause shaking in dogs?
Yes, anxiety can cause shaking. However, medical causes—especially pain—should always be ruled out first.

Why is my dog shaking and panting?

Shaking combined with panting can be a sign of pain, stress, overheating, or illness. In some cases, it may indicate more serious conditions such as toxin exposure or internal discomfort. If these symptoms occur together and do not resolve quickly, your dog should be evaluated by a veterinarian.

How long is it normal for a dog to shake?

Brief episodes of shaking—such as from excitement, anxiety, or being cold—may be normal and should resolve quickly. However, shaking that persists for more than a short period, recurs frequently, or is accompanied by other symptoms should be evaluated.

Do certain dog breeds shake more than others?

Yes. Smaller breeds such as Chihuahuas, terriers, and some toy breeds may be more prone to shaking due to excitement, anxiety, or sensitivity to temperature. However, shaking should not automatically be assumed to be normal—medical causes should still be considered.

Can toxins cause shaking in dogs?

Yes. Certain toxins, including chocolate, medications, and household substances, can cause shaking or tremors. If you suspect your dog may have ingested something toxic, this should be treated as urgent and evaluated immediately.

How can I tell if my dog is shaking from pain or anxiety?

It can be difficult to tell the difference. Dogs shaking from pain may also show signs such as decreased appetite, reluctance to move, or sensitivity to touch. Anxiety-related shaking is often associated with specific triggers, such as loud noises or stressful situations. When in doubt, a veterinary evaluation is the safest way to determine the cause.
