Metaldehyde Poisoning in Dogs

Metaldehyde -- an ingredient of slug and snail baits, and sometimes solid fuel for camp stoves --  is poisonous in dogs, primarily affecting their nervous system. This type of poisoning is often seen in coastal and low-lying areas, where use of slug and snail bait is customary. And even though metaldehyde poisoning can be seen in both dogs and cats, it is more common in dogs.

Symptoms and Types


Metaldehyde ingestion.


You will need to give a thorough history of your dog’s health, including the onset and nature of the symptoms, to your veterinarian. The questions may specifically pertain to exposure to slug and snail baits or other sources of metaldehyde. He or she will then conduct a complete physical examination, as well as a biochemistry profile, urinalysis, and complete blood count (CBC) -- the results of which may be varied. A definitive diagnosis is typically made by verifying the presence of metaldehyde in bodily fluids (e.g., vomitus, stomach contents, and urine).
