Why Is My Dog Shaking? Common Causes and What to Do
Dogs sometimes tremble, quiver, or shiver, and while it can be completely normal, it can also signal something more concerning. Many pet parents notice dog shaking during storms, after a bath, or even at the vet, and wonder if it’s harmless excitement or a sign of illness. Understanding the reasons behind this behavior is essential for keeping your furry friend safe, comfortable, and healthy.
Why Dogs Shake in Normal Situations
Not all shaking is a red flag. In fact, there are many harmless reasons for tremors:
-
Excitement and anticipation
Your dog may shake with enthusiasm before mealtime, when meeting new people, or during play. This type of trembling usually stops once the excitement has passed. -
Cooling down after being wet
One of the most recognizable forms of shaking is when dogs shake off water after swimming or bathing. This full-body shake is completely natural and helps remove moisture from their fur. -
Shivering from the cold
Just like humans, dogs may shiver when temperatures drop. Short-haired or small breeds are particularly prone to cold-induced shaking. -
Post-nap stretching
Some dogs shake themselves awake after a nap, almost as a way to “reset” their bodies.
These everyday scenarios typically require no intervention.
Medical Causes
While many cases are harmless, frequent or unusual shaking can indicate health issues. Pet parents should be aware of the following medical causes:
-
Pain or injury
Shaking may be a dog’s subtle way of showing discomfort. Joint pain, muscle injuries, or internal issues may cause trembling alongside limping, whining, or reluctance to move. -
Poisoning or toxin ingestion
Certain foods and substances, like chocolate, grapes, xylitol, or household chemicals, can trigger severe dog shaking. Other symptoms may include vomiting, diarrhea, drooling, or seizures. This situation is always an emergency—contact a vet immediately. -
Generalized Tremor Syndrome (GTS)
Also called “white shaker dog syndrome,” GTS is a neurological condition that causes persistent body tremors. Though more common in small breeds, it can occur in any dog and typically requires medication to manage. -
Neurological conditions
Seizures, nerve disorders, or age-related cognitive issues can all manifest as dog shaking. These cases often involve other symptoms such as uncoordinated movements or confusion. -
Hypoglycemia
Low blood sugar, especially in toy breeds or puppies, can cause trembling. If untreated, it may progress to seizures. -
Illnesses like kidney disease or distemper
Systemic health problems sometimes include trembling as a symptom. Always check for additional warning signs like weight loss, lethargy, or unusual behavior.
Emotional Causes of Shaking
Beyond physical health, emotional triggers can lead to dog shaking:
-
Anxiety and fear
Fireworks, thunderstorms, or even a trip to the vet can create anxiety-induced trembling. Dogs may also pace, whine, or seek comfort during these moments. -
Separation anxiety
Some dogs shake when left alone or when they anticipate their owner’s departure. -
Trauma or past experiences
Rescue dogs or those with a history of mistreatment may shake in response to loud noises, unfamiliar people, or sudden movements.
Recognizing these emotional triggers is key to helping your dog feel safe and secure.
When to Be Concerned About Dog Shaking
Not all shaking needs medical attention, but you should watch for red flags:
- Shaking accompanied by vomiting, diarrhea, or lethargy
- Sudden onset trembling with no clear cause
- Difficulty standing, walking, or controlling movements
- Shaking paired with excessive drooling, seizures, or disorientation
- Persistent tremors that don’t stop with comfort or warmth
If you notice any of these, contact your veterinarian right away.
How to Help a Dog That’s Shaking
If your dog is trembling, here are steps you can take to provide comfort and safety:
- Check the environment – Is it too cold, loud, or stressful? Adjust conditions to help your dog relax.
- Offer warmth or cooling – Provide a cozy blanket in cold weather or a cooling mat during hot days.
- Stay calm yourself – Dogs pick up on human emotions; offering calm reassurance can ease their anxiety.
- Remove toxins and hazards – Ensure your pup hasn’t ingested harmful substances.
- Provide calming aids – Anxiety vests, pheromone diffusers, or vet-approved supplements can help anxious dogs.
- Maintain a consistent routine – Predictable feeding, walking, and bedtime routines build a sense of security.
If dog shaking continues despite these measures, professional veterinary care is always the safest option.
