Why Is My Dog Shaking? 9 Potential Causes

At some point, most dog owners have probably noticed their dog shaking. Not knowing the cause can be frightening. So why do dogs shake and tremble? Most of the time, a dog shaking or shivering is nothing more than an expression of anxiety or fear. However, it can also be a sign of serious medical issues.

In this article, we’ll discuss some of the most common causes of shaking in dogs and how to determine when they warrant medical intervention. 

Dog Shaking: Common Causes

It may be difficult to pinpoint exactly why your dog is shaking. But knowing the different causes of shaking in dogs can help you determine if your dog is probably OK or needs a trip to the vet. Let’s have a look at nine common causes of shaking, trembling, or shivering in dogs.

1. Anxiety and fear

It’s common for dogs to shake or tremble when they experience fear or anxiety.¹ Every dog has different triggers; some common ones include fireworks or thunderstorms.

If your dog is anxious, do your best to comfort them. Talk to them in a calm, reassuring tone. Try to create a safe space where they feel protected. If you can remove your furry friend from the situation causing their anxiety, do so immediately. Otherwise, do your best to comfort them until their fears subside. If your dog is aggressive, that could mean you should give them some space.

If anxiety is an ongoing issue for your dog, speak to your veterinarian. There may be medication they can prescribe to help relieve symptoms during certain situations.

2. Excitement

Many dogs will tremble out of excitement. This is often not a cause for concern, and usually the pup’s excitement will subside after a few minutes. Young or very high-energy dogs may take longer to calm down.

You can help calm your dog by speaking to them in a gentle voice. You may also try to keep your movements slow and deliberate so you don’t add to their excitement.

3. Wet coat

If a dog is shaking after taking a bath, being out in the rain, or getting wet in another way, they’re likely shaking to help themself dry off. This type of shaking looks a little different from constant shivering or trembling. Look for a few short, vigorous shakes in a row. This is a completely normal and effective way for your pup to rid their fur of moisture.

After your dog has shaken off their coat a few times, if they continue to tremble or shake, it’s possible that they’re cold from getting wet.

4. Cold

Dogs may have furry coats, but they can still get cold. If you notice your dog trembling on a chilly day or after being wet, it’s possible they’re shivering.

If your pup doesn’t have a thick undercoat, they may need a sweater or jacket to help keep them warm during cold snaps. Try to make sure your pup has a warm place to rest and sleep. If their bed is on a tile or concrete floor, place a piece of cardboard underneath it for extra insulation. Make sure the bed is situated out of the way of any cool drafts and away from windows.

5. Age

Many dogs develop tremors as they age. This is often due to their muscles weakening as they get older. It could also be a result of their nervous system deteriorating. If your older dog suddenly develops a tremor, be sure to take them in for a checkup with your vet. There’s a possibility that the tremor is indicative of a more serious underlying issue.

6. Pain

Trembling can be a sign that your dog is in pain. Usually, pain-related tremors are accompanied by other symptoms as well.² Take note of your dog’s overall posture and behavior, looking for any indication of pain. Is your dog limping or stiff, which could be signs of arthritis or a ligament injury? Are they restless?

Often, dogs who are in pain will shift position constantly, trying to find one that alleviates their discomfort.² They often pace and may whine, cry, or even drool excessively. If your dog is exhibiting any combination of these symptoms, contact your veterinarian immediately.

7. Illness or chronic medical conditions

Sometimes, dog shaking is a side effect of a medical condition — such as seizures, kidney disease, distemper, vestibular disease, and other medical conditions.² Nausea and low blood sugar (hypoglycemia) can also cause a dog to tremble.^3,4

If you notice any changes in your dog’s behavior or physical state, take note of them. If there’s an underlying medical condition, the tremors may just be one of many symptoms. Consider your dog’s energy levels, appetite, stool consistency, and anything else that might seem off. This information will help your veterinarian make an accurate diagnosis.

8. Poisoning

There are many signs that a dog has ingested something poisonous, one of which is tremors. Unfortunately, dogs can eat or chew something toxic to them in an instant — such as foods like grapes, chocolate, or onions that have fallen on the floor. Many household cleaning products, human medications, and commonplace plants can poison a dog as well.⁵

If you think your dog may be shaking because of poisoning, this is considered a medical emergency.⁵ So you should visit your vet or an emergency clinic as soon as possible.

9. Shaker syndrome

Shaker syndrome can affect any dog, though it most often affects small dogs.⁶ It’s sometimes referred to as “little white shaker syndrome” because many cases occur in small, white-furred dogs — such as the Maltese, poodle, and Maltipoo breeds.

This hereditary disorder affects a dog’s nervous system. The exact cause is unknown, but once diagnosed, this syndrome can be managed with medication.⁶

When to Bring a Shaking Dog to the Vet

A trip to the vet might not be necessary if your dog’s shaking is related to being wet, cold for a brief time, or excited. However, if you’re unable to determine the cause, a vet visit is probably a good idea. Signs of pain, illness, or poisoning should be taken especially seriously.

Because shaking and trembling can have so many different causes, it’s important to take note of all of your dog’s symptoms and address them as a whole with your vet. Generally, if your dog doesn’t typically tremble, contact your veterinarian to ensure they aren’t experiencing a serious medical issue. It may be wise to play it safe when it comes to the well-being of your furry friend.
