# Is Corry's Snail Bait Toxic to Dogs? Slug Killer Risk Is Corry's snail bait toxic to dogs? Yes, if the product contains metaldehyde, and that ingredient is one of the most dangerous garden poisons a dog can swallow. Many Corry's slug and snail killer products are metaldehyde-based, so a dog that eats the bait can develop tremors, seizures, and life-threatening overheating within hours. This article is educational and is not a substitute for veterinary diagnosis or treatment. ## Quick Answer - Metaldehyde slug and snail baits are significantly toxic to pets and can cause vomiting, diarrhea, panting, fever, tremors, seizures, dilated pupils, and lethargy [1]. - Signs can start within a few hours of eating bait and can progress fast, so treat any suspected ingestion as an emergency [2]. - Call your veterinarian, the ASPCA Animal Poison Control Center at (888) 426-4435, or Pet Poison Helpline at (855) 764-7661 right away. - Do not induce vomiting unless a veterinarian tells you to. - Bring the product label or package with you so the veterinary team knows exactly what your dog ate. ## Is Corry's Snail Bait Toxic to Dogs? Corry's makes several slug and snail products, and the risk depends entirely on the active ingredient on the label. If the label lists metaldehyde, the product is highly toxic to dogs. Metaldehyde baits come as granules, pellets, liquids, and powders, and all of those forms are dangerous [1]. If the label lists iron EDTA (also called ferric sodium EDTA or iron phosphate in some products), that is a different situation. Iron EDTA molluscicide ingestion in dogs most often causes gastrointestinal signs such as abnormal stools, and some dogs develop concerning serum iron levels that need treatment [3]. That is still a reason to call a veterinarian, but it is not the same emergency as metaldehyde. So the first step is simple. Read the active ingredient on the package. If you cannot find the package, call poison control and describe what you can remember about the product. ### Which parts of the product are dangerous? The bait itself is the danger. Dogs are attracted to metaldehyde pellets because they often contain bran, molasses, or other food-like ingredients. A dog may eat bait straight from the garden bed, from a spilled pile, or from a container left within reach. The area where bait was applied also matters. Ground treated with metaldehyde bait should be considered contaminated for at least 2 weeks after application, and newer moisture-resistant formulations can stay risky even beyond that window [1]. That means a dog can be poisoned by scavenging pellets days or weeks after you thought the yard was safe. ## What Metaldehyde Does in the Body Metaldehyde is a pesticide used mainly as a molluscicide, and it is responsible for intoxication and death in both people and animals [2]. When a dog swallows it, the toxin reaches the nervous system and triggers uncontrolled electrical activity. That is why the signs look neurological: tremors, rigidity, and seizures. The body also heats up during those episodes. Panting and fever are common, and severe cases can progress to dangerous hyperthermia. In a reported fatal case, an 11-month-old German Spitz weighing 3.0 kg developed acute vomiting and seizures 3 hours after eating a commercial molluscicide containing 3% metaldehyde [2]. That timeline is typical. Three hours from ingestion to seizures is fast, and it shows why waiting to "see if symptoms develop" is a bad plan. Metaldehyde poisoning is not rare in veterinary practice. In a three-year retrospective analysis of suspected poisonings, 50 of 183 animal organ samples (27.3%) tested positive for metaldehyde [4]. The researchers called for better control of metaldehyde use by veterinary services [4]. In other words, this is a well-documented problem, not a one-off worry. ## Signs of Metaldehyde Poisoning and When They Appear The classic signs of metaldehyde poisoning in animals include vomiting, diarrhea, panting, fever, tremors, seizures, dilated pupils, and lethargy [1]. You may see only one or two of these at first. Anxiety, unsteadiness, and muscle twitching often come before full seizures. Timing matters. Signs often begin within 1 to 3 hours of ingestion, and the case report above described seizures at 3 hours [2]. Some dogs deteriorate very quickly after the first sign appears. If your dog is already trembling or having trouble standing, that is a now emergency, not a wait-and-watch situation. ### Early signs - Vomiting or diarrhea - Restlessness, pacing, or anxiety - Panting that seems out of proportion to the weather - Mild muscle twitching - Dilated pupils ### Advanced signs - Whole-body tremors or rigidity - Seizures, including continuous seizure activity - Fever and overheating - Depression, stupor, or unresponsiveness - Difficulty breathing - Fast heart rate A dog with severe metaldehyde poisoning can be in lateral recumbency with stupor, salivation, continuous seizures, tremors, pinpoint pupils, and depressed reflexes [2]. That level of illness needs immediate hospital care. ## What to Do Right Now 1. Move your dog away from the bait and any treated area. 2. Call your veterinarian, the ASPCA Animal Poison Control Center at (888) 426-4435, or Pet Poison Helpline at (855) 764-7661. 3. Tell them the product name, the active ingredient percentage if you have it, how much you think your dog ate, and when it happened. 4. Do not induce vomiting unless a veterinarian tells you to. Metaldehyde can cause seizures, and forcing vomiting in a seizing or twitching dog can lead to aspiration. 5. Do not give food, milk, oil, or home remedies. They do not help and can delay real treatment. 6. Bring the label, the bag, or a photo of the ingredient panel with you. If your dog is already seizing, collapsing, or struggling to breathe, skip the phone call and go straight to the nearest emergency veterinary hospital. Have someone call ahead so the team is ready when you arrive. If you are also worried about other things your dog picks up outdoors, our guide on [what to do if your dog ate a slug or snail](/knowledge/veterinary-medicine/vet-visit-decisions/dog-ate-slug-snail-lungworm) covers a different but related concern, and our article on [dogs and toxic mushrooms](/knowledge/veterinary-medicine/vet-visit-decisions/dog-ate-mushroom-toxic) explains how to think through unknown outdoor ingestions. ## How Veterinarians Treat Metaldehyde Poisoning Treatment starts with decontamination when it is safe. That may include inducing vomiting under veterinary supervision, giving activated charcoal, or pumping the stomach, depending on how much time has passed and how the dog is doing. Next comes seizure and tremor control. Veterinarians use injectable medications to stop the abnormal brain activity, along with intravenous fluids, cooling measures for fever, and oxygen if needed. Muscle activity from tremors and seizures generates heat, so controlling the tremors also helps control body temperature. Some severe cases do not respond to standard medical therapy. A recent case series described three dogs with severe metaldehyde intoxication whose seizures and uncontrollable tremors did not improve with gastric decontamination, medical therapy, and intravenous lipid emulsion. Emergency hemodialysis using a medium cut-off dialyzer resolved the neurological signs in all three dogs within a 4-hour session, and the dialyzer cleared metaldehyde 12.5 times faster than the dogs' own intrinsic clearance [5]. That is advanced, referral-level care, and it is not available everywhere. It does show that even very sick dogs can recover with aggressive treatment. The dose that causes poisoning varies with the product concentration, the dog's size, and how much was eaten. Your veterinarian calculates the risk from your dog's weight and the label information. There is no safe home dose to memorize. ## Outlook for a Dog That Ate Snail Bait The outlook depends on how much metaldehyde the dog ate, how quickly treatment started, and how severe the neurological signs become. Dogs treated early, before seizures set in, generally do better. Dogs that arrive already seizing or overheated are at much higher risk of death, and metaldehyde poisoning is a documented cause of fatalities in dogs [2]. Even with treatment, some dogs need days of hospitalization. Others recover fully. Your veterinarian can give you a realistic picture once they examine your dog and see how it responds to the first round of treatment. ## Preventing Metaldehyde Poisoning The safest approach is to stop using metaldehyde products if you have a dog. Choose a molluscicide with a different active ingredient, or use physical barriers, hand-picking, and copper tape instead. If you must use any slug bait, keep your dog away from treated areas for at least 2 weeks, and longer if the label says the product is weather-resistant [1]. Store all garden chemicals in a locked cabinet, never in a garage shelf your dog can reach. Pick up spilled pellets immediately. Watch for bait stations that other people, neighbors, or landscaping crews may have placed near your property line. If your dog eats plants or outdoor items regularly, our guide to [plants poisonous to dogs](/knowledge/veterinary-medicine/toxicology-and-food-safety/plants-poisonous-to-dogs) is a useful reference for the rest of your yard. And if your dog has a habit of eating things it should not, our article on [plum toxicity and pit risks](/knowledge/veterinary-medicine/toxicology-food-safety/can-dogs-eat-plums-toxicity-warnings-pit-risks) explains how to think about fruit and pit hazards. ## Limitations and When to Contact a Veterinarian Contact a veterinarian the same day if your dog may have eaten bait but seems normal. Early decontamination can prevent severe signs, and a normal-looking dog can deteriorate within hours. Go to an emergency hospital now if your dog is trembling, twitching, having a seizure, panting heavily, vomiting repeatedly, unable to stand, or acting disoriented. These are red flags for metaldehyde poisoning and need treatment without delay [1][2]. Schedule a routine visit if your dog had a possible exposure weeks ago and now has vague signs such as appetite changes or lethargy. Your veterinarian can examine your dog and decide whether bloodwork or other testing is needed. Every case is different, and only a veterinarian who examines your dog can decide on the right treatment plan. ## Frequently Asked Questions ### Is Corry's slug bait harmful to dogs if they only eat a little? Yes, even a small amount can be dangerous because metaldehyde acts quickly on the nervous system. The risk depends on the product's concentration and your dog's size, so any known ingestion deserves a call to poison control or your veterinarian. Do not wait for signs to appear before seeking advice. ### Is Corry's slug and snail killer toxic to dogs if it has been raining? Yes, rain does not make metaldehyde bait safe. Some newer formulations are resistant to moisture and breakdown, which means treated areas can stay risky for pets even after 2 weeks from application [1]. Keep your dog away from the area and call poison control if you think bait was eaten. ### Can a dog survive metaldehyde poisoning? Yes, many dogs survive with fast, aggressive treatment. Survival is more likely when decontamination and seizure control start early, before severe neurological signs develop. Dogs that arrive already seizing or overheated have a much higher risk of death [2]. ### Should I make my dog vomit after eating snail bait? No, do not induce vomiting unless a veterinarian tells you to. Metaldehyde can cause seizures and tremors, and vomiting during a seizure can cause aspiration into the lungs. Call your veterinarian or poison control first and follow their instructions. ### How long do metaldehyde poisoning signs last in dogs? Signs can last from hours to several days, depending on how much was eaten and how quickly treatment starts. Tremors and seizures may continue until the toxin is cleared and medication controls the brain activity. Your veterinarian will monitor your dog and adjust treatment based on its response. ## Related Articles - [My Dog Ate a Slug or Snail: Should I Worry About Lungworm?](/knowledge/veterinary-medicine/vet-visit-decisions/dog-ate-slug-snail-lungworm) - [My Dog Ate a Mushroom: How to Tell If It's Toxic](/knowledge/veterinary-medicine/vet-visit-decisions/dog-ate-mushroom-toxic) - [Can Dogs Eat Plums?
