Dog Shaking
Seeing your dog shake or tremble can be unsettling. This page walks you through common reasons dogs shake, what you can safely do at home, and when it is time to call your vet right away.
When to Call a Vet
Go to the ER now
- ● Go to an emergency vet now if your dog is having a seizure, collapses, becomes unresponsive, or has shaking with loss of consciousness.
- ● Seek urgent emergency care if shaking happens with trouble breathing, blue or pale gums, or severe weakness.
- ● Go now if your dog may have eaten a toxin, moldy food, compost, chocolate, xylitol, nicotine products, or other unsafe substances.
- ● Get immediate help if the shaking is intense and comes with repeated vomiting, severe diarrhea, a swollen or painful belly, or signs of severe pain.
- ● Treat it as an emergency if the shaking lasts several minutes, keeps recurring, or is paired with stumbling, inability to stand, or marked confusion.
See a vet within 24 hours
- ● Call your vet the same day if shaking is new, unexplained, or keeps coming back.
- ● Make a prompt appointment if your dog seems painful, nauseated, restless, or is hiding, whining, or refusing food.
- ● Call your vet soon if your dog is shaking their head often, especially with red ears, odor, discharge, or after swimming or a bath.
- ● Have your dog seen promptly if shaking starts in a puppy, toy breed, senior dog, or a dog with diabetes or another known medical condition.
- ● Contact your vet if your dog has tremors that worsen with excitement or activity, or if you notice eye movements, poor coordination, or other neurologic changes.
Watch at home, call if it worsens
- ● You can monitor briefly if the shaking clearly happens after getting wet or cold and stops once your dog is dried and warmed up.
- ● Mild trembling with excitement or temporary stress may be less concerning if your dog is otherwise acting completely normal.
- ● A single short episode may be reasonable to watch if your dog is eating, drinking, walking normally, and has no other symptoms.
- ● Monitor at home if your dog does an occasional full-body shake to reset after stress, handling, or a bath and then returns to normal right away.
- ● Even mild shaking should be discussed with your vet if it does not fully resolve, becomes more frequent, or you are not sure of the cause.
Common Causes of Dog Shaking
Stress or excitement
Some dogs tremble when they are anxious, overstimulated, or excited. A brief whole-body shake can also be a normal way dogs release tension.
Cold or being wet
Dogs may shiver when they are chilled, especially small dogs, puppies, seniors, or dogs with thin coats. Shaking after a bath or swim may stop once they are dry and warm.
Pain or nausea
Shaking can be a sign that a dog feels painful or sick to their stomach. You may also notice restlessness, lip licking, panting, hiding, or a lowered appetite.
Ear problems
Frequent head shaking can happen with ear infections or ear irritation. Redness, odor, discharge, or tenderness around the ears are common clues.
Neurologic causes
Tremors and seizures can both look like shaking. Some dogs have generalized tremor syndromes, while others may have seizures, balance problems, or other nervous system disease.
Toxins or metabolic illness
Poisoning, low blood sugar, and problems involving the liver, kidneys, or electrolytes can cause trembling. These cases often need veterinary care quickly.
What to Do at Home
If your dog is shaking, try to stay calm and look for the full picture. Mild trembling can happen with stress, cold, or excitement, but shaking can also be one of the first signs of pain, nausea, poisoning, or a neurologic problem. If your dog seems otherwise normal, you can do a few basic checks at home while deciding whether to call your vet.
- Move your dog to a quiet, safe area away from stairs, water, and anything they could fall against.
- If your dog is cold or wet, dry them off and offer gentle warmth with a blanket. Do not use intense heat.
- Watch for other symptoms such as vomiting, diarrhea, trouble walking, confusion, collapse, head tilt, abnormal eye movements, or difficulty breathing.
- Check the ears if your dog is shaking their head. Redness, odor, discharge, or pain are reasons to call your vet.
- Record a short video of the shaking episode if you can do so safely. This can be very helpful for your veterinarian.
- Do not give human medications, do not force food or water, and do not try to make your dog vomit unless a veterinarian specifically tells you to.

My Dog Is Shaking but Acting Normal — Should I Worry?
Sometimes a dog can tremble and still seem completely normal otherwise. Mild shaking may happen if your dog is cold, wet, excited, stressed, or simply older and a bit shakier than they used to be. In many dogs, these episodes are brief and stop once the trigger passes. Even so, acting normal does not always mean nothing is wrong. Shaking can also be an early clue for pain, nausea, low blood sugar, toxin exposure, or a neurologic problem before other symptoms become obvious. It is more reassuring if your dog stops shaking quickly, eats and drinks normally, walks normally, and has a clear reason for the episode. It is more concerning if the shaking is new, keeps happening, gets worse, or comes with weakness, vomiting, trouble walking, confusion, pale gums, or trouble breathing.
- Less concerning causes include being cold, getting wet, excitement, stress, or a brief post-bath or post-stress full-body shake.
- Some older dogs may tremble more because of age-related weakness, arthritis discomfort, or general frailty, even if they still seem mostly normal.
- Watch for warning signs such as pain, vomiting, diarrhea, stumbling, disorientation, collapse, pale gums, or difficulty breathing.
- If the shaking has no clear cause, keeps returning, or your dog is very young, very small, senior, or has a medical condition like diabetes, call your vet.
- If you can do so safely, take a short video to show your veterinarian exactly what the episode looks like.
