Most Common Toxicologic Causes of Tremors in Dogs

There are a variety of toxic causes for sudden onset tremors in previously healthy dogs. Determining a cause helps determine the prognosis, what other signs can be expected, and how to formulate a comprehensive treatment plan.

After you reach for the methocarbamol, reach for this list to see if the pet has had an exposure to one of these substances.

NOTE: Many of the medications commonly used in veterinary medicine on this list are only an issue in overdose situations (for example, permethrin can cause tremors when an undiluted dip is applied to a small dog) or when drug-drug interactions increase the toxicity (like when high-dose ivermectin and ketoconazole are used together).
