-
Dreaming – Light twitching or shaking can happen during sleep.

Nausea or Upset Stomach – Shaking sometimes accompanies vomiting or diarrhea.
-
Toxins / Poisoning – Eating something toxic (like chocolate, xylitol, certain plants) can cause shaking.
-

🚨 When to See a Vet Immediately
Take your dog to the vet right away if shaking is accompanied by:
-
Vomiting or diarrhea
-
Trouble walking or standing
-
Seizures or collapse
-
Extreme lethargy
-
Pale or blue gums

Recent ingestion of something unusual/toxic
👉 Sometimes shaking is just excitement, but if it happens suddenly, frequently, or with other symptoms, it’s best to call your vet.
