should I be worried if my dog is shaking

Seeing your dog shaking can be unsettling. Whether they’re trembling all over or just shivering slightly, it’s natural to feel concerned. So, should you be worried if your dog is shaking? The answer depends on the context. Dogs can shake for many reasons—some harmless, others more serious. Understanding the cause is key to knowing when to offer comfort and when it’s time to call the vet.

Common Non-Emergency Causes of Shaking

Dogs often shake due to temporary or harmless reasons. Excitement is a big one. Some dogs shake when they’re overly stimulated—during playtime, when greeting their favourite person, or when anticipating a treat or walk. Shaking can also happen after exercise or a bath, as a way of relieving tension or drying off.

Cold weather is another simple cause. Just like us, dogs can shiver when they’re chilly. Short-haired breeds, puppies, and smaller dogs are particularly prone to this. If that’s the case, a warm blanket or dog jumper can solve the issue quickly.

Mild shaking can also happen after a stressful event—like a trip to the vet or loud fireworks. This is usually linked to adrenaline and anxiety, and settles down once the dog feels safe again.

When Shaking Could Be a Concern

Shaking can also be a symptom of something more serious. If your dog is shaking along with other symptoms—such as vomiting, diarrhoea, drooling, lethargy, or pain—it could signal illness or poisoning. In this case, you should contact your vet straight away.

Shaking may also be a sign of pain or injury. If your dog is limping, flinching when touched, or holding their body stiffly, the trembling could be their way of reacting to discomfort.

In older dogs, shaking might point to joint pain, weakness, or even neurological problems. If your dog starts shaking more frequently or if their balance seems off, it’s best to get them checked over.

Certain breeds, like Chihuahuas and Terriers, are more prone to trembling in general, but that doesn’t mean you should ignore sudden changes in behaviour.

Medical Conditions Linked to Shaking

There are several medical issues where shaking is a symptom. These include canine distemper, low blood sugar (hypoglycaemia), seizure disorders, kidney disease, and addison’s disease. Many of these come with additional symptoms like loss of appetite, weakness, or collapse.

Ingesting something toxic—such as chocolate, xylitol, or certain plants—can also cause shaking and should be treated as an emergency.

If you’re ever in doubt, it’s safer to call your vet and explain what’s happening. A quick chat can help rule out serious problems or get you in sooner if needed.

What to Do If Your Dog Is Shaking

Start by observing your dog closely. Are they acting normally otherwise—eating, drinking, walking, and responding to you as usual? If so, and the shaking is short-lived, it may be nothing to worry about. Keep them warm and calm, and monitor their behaviour over the next few hours.

If the shaking continues, becomes more intense, or is paired with other signs like vomiting, disorientation, or crying out, then you should seek veterinary help as soon as possible.

Keep a note of when the shaking started, what your dog was doing before it happened, and whether anything else has changed recently. This can help your vet diagnose the problem more quickly.

Summary

Not all shaking in dogs is a cause for alarm. Sometimes it’s just excitement, cold, or stress. But if shaking is paired with other symptoms or comes on suddenly without an obvious reason, it could point to pain, illness, or poisoning. When in doubt, always speak to your vet—it’s better to be safe and catch a problem early than risk waiting too long. With close attention and quick action, you’ll be able to help your dog feel better fast.
