If your dog has eaten something poisonous, call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately. Do not give your dog anything or try to induce vomiting until you’ve spoken with a professional. The right response depends entirely on what your dog swallowed, how much, and how long ago.
Speed matters. Many toxins are absorbed within 30 to 60 minutes, so the sooner you act, the better your dog’s chances. Here’s what you need to know about each step.
What to Do in the First Few Minutes
Stay calm and gather information. Before you call anyone, figure out what your dog got into, roughly how much they consumed, and when it happened. If there’s a product label or packaging, keep it nearby. Your dog’s weight will also be important for calculating any treatment doses.
If the poison was inhaled (like fumes from cleaning products), move your dog into fresh air right away. If a powder or granular substance is on your dog’s fur, brush or vacuum it off before it can be licked or absorbed. For liquids on the skin, don’t rinse until you’ve called a vet, because water actually activates some toxins and can make things worse.
If the poison got into your dog’s eyes, flush them with room-temperature saline or water for at least 10 minutes. For caustic substances like bleach or drain cleaner, flush for 15 to 20 minutes. Room-temperature milk works as a second choice if you run out of saline.
When Inducing Vomiting Is Appropriate
The most common at-home treatment for ingested poison is 3% household hydrogen peroxide given by mouth. The standard dose is about 1 milliliter per pound of body weight, with a maximum of 45 mL regardless of size. You can draw it into a syringe (without a needle) and squirt it toward the back of your dog’s tongue.
If your dog hasn’t vomited within 15 minutes, you can give one additional half-dose (0.5 mL per pound). After that second attempt, stop. Do not give any more peroxide.
This is critical: only induce vomiting if a veterinarian or poison control tells you to. Vomiting is helpful for some toxins but dangerous for others, and guessing wrong can cause serious harm.
When You Should Never Induce Vomiting
Some substances cause far more damage coming back up than they did going down. Never try to make your dog vomit if they swallowed:
- Corrosive chemicals like bleach, drain cleaner, oven cleaner, or strong acids. These burn tissue on the way down and will burn again on the way back up, doubling the injury to the esophagus and mouth.
- Petroleum products like gasoline, kerosene, or motor oil. These can be inhaled into the lungs during vomiting, causing chemical pneumonia.
- Batteries that may have been punctured or chewed. Alkaline gel leaking from a damaged battery can severely burn the mouth and throat during vomiting.
- Cationic detergents found in some fabric softeners and disinfectants.
You should also skip vomiting if your dog is already having seizures, is losing consciousness, or is having trouble breathing. In these cases, get to an emergency vet immediately.
What About Activated Charcoal?
Activated charcoal works by binding to toxins in the stomach and intestines, preventing them from being absorbed into the bloodstream. It’s most effective when given as soon as possible after ingestion. In human medicine, giving it beyond one hour is generally considered less useful, but in dogs it can still help up to six hours later for certain slow-release toxins.
The typical dose is 1 to 5 grams per kilogram of body weight. Activated charcoal is usually administered at the veterinary clinic rather than at home, because getting the dose right matters and some formulations include a laxative component that shouldn’t be repeated. If your vet recommends it, they’ll likely give it through a syringe or stomach tube.
Do not grab activated charcoal capsules from a health food store and try to dose your dog yourself. The concentration is too low to be effective, and without veterinary guidance you risk complications.
Home Remedies That Don’t Work
You may have heard that giving a poisoned dog milk, bread, or salt water can help. None of these are reliable treatments, and some are actively harmful.
Most dogs lack enough of the enzyme that digests lactose, so milk is likely to cause diarrhea and further dehydration without neutralizing any toxin. Bread does nothing meaningful to absorb poison. Salt is especially dangerous: excessive salt intake can cause abnormal blood electrolytes, tremors, seizures, and even death. Never use salt to try to make your dog vomit.
Signs Your Dog Has Been Poisoned
Sometimes you won’t catch your dog in the act. Symptoms vary widely depending on the substance, but common signs of poisoning include vomiting, diarrhea, drooling or foaming at the mouth, dilated pupils, trembling, seizures, extreme drowsiness or sudden hyperactivity, difficulty breathing, and collapse. You might also notice red or swollen skin, burns around the lips or mouth, or ulcers on the gums.
Some toxins act within minutes. Others take hours or even days. Anticoagulant rodenticides (rat poison), for example, may not cause visible symptoms for several days, by which point internal bleeding has already begun. Chocolate toxicity depends on the type: baking chocolate is roughly seven times more concentrated than milk chocolate, so a small amount of baking chocolate can cause serious cardiac and neurological symptoms in a medium-sized dog, while the same weight of milk chocolate might only cause an upset stomach.
What Happens at the Vet
Once you reach the veterinary clinic, treatment depends on the toxin and how much time has passed. Your vet may induce vomiting using clinical-grade medications that are more effective and controlled than hydrogen peroxide. They may administer activated charcoal to catch whatever hasn’t been absorbed yet.
For more serious cases, your dog may receive IV fluids to maintain blood pressure and help the kidneys flush the toxin out. If the specific poison has a known antidote, your vet will administer it. Rodenticide poisoning from anticoagulant bait, for example, is treated with vitamin K therapy that may need to continue for weeks at home.
Some dogs need monitoring for 24 to 72 hours depending on the substance. Others can go home the same day. The earlier you get treatment started, the shorter and simpler recovery tends to be.
