Slug/Snail Bait (Metaldehyde) — toxicity in dogs and cats

EmergencyApplies to: dogs and cats.

Overview

Slug and snail baits containing metaldehyde are extremely toxic to dogs and cats. These products are sold as pellets, granules, or liquid formulations and are commonly used in gardens throughout the spring and summer. The pellets often contain bran or molasses to attract slugs, which unfortunately also attracts dogs. Metaldehyde poisoning causes severe, uncontrollable muscle tremors and seizures that can lead to hyperthermia (dangerously elevated body temperature) and death within hours if untreated. There is no specific antidote - treatment is supportive and focused on controlling seizures and lowering body temperature. If you use slug bait in your garden, switch to pet-safe alternatives containing iron phosphate instead of metaldehyde.

Symptoms

Tremors, seizures, hyperthermia, rapid breathing

Typical onset

1-3 hours
