Your dog is shaking and you're not sure why. The good news: most of the time, it's nothing serious. But sometimes shaking is your dog's way of telling you something is wrong.
Normal Reasons Dogs Shake
These are usually nothing to worry about:
- Cold — Small dogs, thin-coated breeds, and senior dogs get cold easily. If they're shaking and the room is chilly, that's your answer.
- Excitement — Many dogs tremble when they're excited — before a walk, when you get home, or when food is coming. It's just overflow energy.
- Drying off — The post-bath shake. Totally normal and impressively effective (dogs can shake off 70% of the water on their fur in seconds).
- Dreaming — Dogs twitch, paddle, and shake during REM sleep. If they're asleep and twitching, they're probably chasing a squirrel in their dreams.
Reasons That Need Attention
- Anxiety or fear — Thunderstorms, fireworks, car rides, or vet visits can trigger stress shaking. You'll usually see other signs too: panting, tucked tail, whale eyes, or hiding.
- Pain — Dogs who are in pain sometimes shake or tremble. This is especially common with abdominal pain, joint pain, or back injuries. If the shaking is new and your dog is also reluctant to move, eating less, or vocalizing, pain is a likely cause.
- Nausea — Dogs about to vomit often tremble first. Watch for drooling, lip-licking, and restlessness alongside the shaking.
- Poisoning — Toxin exposure can cause tremors, shaking, and muscle twitching. If your dog may have eaten something toxic (chocolate, xylitol, snail bait, certain plants), this is an emergency.
- Generalized Tremor Syndrome (GTS) — Also called "white shaker dog syndrome" (though it affects all breeds), this causes full-body tremors. It's treatable but needs a vet diagnosis.
- Old age tremors — Senior dogs sometimes develop mild trembling in their legs, often from muscle weakness or early neurological changes. It's usually gradual and worth mentioning at their next checkup.
- Neurological issues — Seizures, brain lesions, or nerve damage can cause shaking. These episodes often look different from normal trembling — they may be rhythmic, affect one side of the body, or come with disorientation.
When to See the Vet
Make an appointment if:
- Shaking is new, persistent, or getting worse
- It's accompanied by vomiting, diarrhea, or loss of appetite
- Your dog seems disoriented or uncoordinated
- You suspect they ate something toxic
- The shaking only affects one part of the body
- Your dog is also limping, whimpering, or refusing to move
If the shaking looks like a seizure (stiffness, loss of consciousness, paddling legs), go to an emergency vet immediately.
What to Do Right Now
For mild, situational shaking: keep your dog warm, remove stressors if possible, and observe. If anxiety is the root cause, talk to your vet about management strategies.
