Is Snail & Slug Bait (Metaldehyde) Safe for Dogs?
Why it’s a problem
Pellets are mixed with molasses or bran, making them attractive enough that dogs eat them straight from the garden. Metaldehyde attacks the nervous system and causes severe overheating. Signs usually start within 1–3 hours, and untreated cases can be fatal.
How to keep your pet safe
Choose iron-phosphate baits instead of metaldehyde, or use physical barriers like copper tape and beer traps. If metaldehyde is used, apply it under plants and in stations your dog cannot reach, and store the bag sealed indoors. Pick up any spilled pellets at once.
Warning signs to watch for
Rapid onset within 1–3 hours: anxiety, panting, drooling, uncoordinated gait, muscle tremors, twitching, seizures, high body temperature, vomiting, diarrhea, collapse.
When to call the vet
This is an emergency measured in minutes to hours — go to a vet or emergency clinic immediately and bring the packaging. Do not induce vomiting unless a professional tells you to. Early aggressive treatment is often successful; waiting usually is not.
Common questions
My dog ate snail pellets from the flower bed — what do I do?
Go to a vet immediately even if he seems fine — signs can start within an hour and escalate fast. Bring the bag so the vet can confirm it contains metaldehyde.
Is iron phosphate slug bait safe for dogs?
Iron phosphate products are much safer and are the standard choice in pet-owning households, though large amounts can still upset the stomach. Follow the label and keep the bag away from your dog.
How fast does metaldehyde kill?
Seizures can begin within 1–3 hours and death can follow from overheating and organ failure. With fast veterinary care many dogs survive, which is why speed matters so much.
