How To Make A Dog Throw Up
Seeing your dog swallow something dangerous is terrifying. Your first instinct might be to make them vomit immediately. However, inducing vomiting in dogs is a clinical procedure that carries significant risks. The American Veterinary Medical Association (AVMA) and the American Animal Hospital Association (AAHA) strongly advise that vomiting should only be induced under the direct supervision of a veterinarian. This article explains the clinical methods used by veterinary professionals, when vomiting is appropriate, and why home remedies can be harmful.
Quick Q&A: Common Questions
Question: Can I make my dog throw up at home using hydrogen peroxide?
Answer: No. Hydrogen peroxide is no longer recommended by veterinary toxicologists and the AVMA due to the risk of severe oesophagitis, aspiration pneumonia, and failure to induce vomiting. Always contact your veterinarian or a pet poison control centre first; they will tell you if induction is safe and guide you on the proper clinical method if needed.
When Inducing Vomiting Is Necessary (And When It Is Not)
Inducing vomiting can be life-saving if your dog has ingested a rapidly absorbed toxin within the last 1–2 hours. Examples include chocolate, xylitol, grapes, raisins, or certain medications. However, vomiting is contraindicated for many substances. The Veterinary Poisons Information Service (VPIS) in the UK and the ASPCA Animal Poison Control Center in the US both advise never to induce vomiting if the dog has swallowed:
- Sharp objects (bones, glass, needles) – vomiting can cause perforation.
- Caustic or corrosive substances (bleach, drain cleaner, batteries) – vomiting re-exposes the oesophagus to damage.
- Petroleum products (gasoline, paint thinner) – aspiration risk is high.
- Large quantities of food or liquid – risk of bloat or aspiration.
Additionally, vomiting should not be induced in dogs that are already vomiting, have difficulty breathing, are unconscious, or have a pre-existing condition such as megaesophagus.
Why You Should Never Induce Vomiting Without Veterinary Guidance
The AVMA and the Canadian Veterinary Medical Association (CVMA) have issued clear statements: inducing vomiting at home without professional advice can cause more harm than the toxin itself. Common home remedies like salt, mustard, or hydrogen peroxide can lead to:
- Aspiration pneumonia – if the dog inhales vomit into the lungs.
- Hypernatremia (salt poisoning) from salt administration, which can cause brain swelling.
- Oesophagitis and strictures from hydrogen peroxide.
- Delayed treatment – time wasted on ineffective induction allows the toxin to be absorbed.
Even when a veterinarian decides vomiting is appropriate, they will assess the dog’s health, the substance ingested, and the time elapsed. In Australia, the Australian Veterinary Association (AVA) recommends contacting a vet or a 24-hour animal poison hotline before any attempt.
Clinical Methods Used by Veterinarians
If induction is indicated, veterinary professionals use safe, controlled methods:
Apomorphine Injection
Apomorphine is the most common emetic used in veterinary clinics. It is injected intramuscularly or intravenously and acts on the brain’s chemoreceptor trigger zone. Vomiting typically occurs within 5–10 minutes. The dog is monitored for excessive sedation or respiratory depression.
Hydrogen Peroxide (Vet-Supervised Only)
Some veterinarians still use 3% hydrogen peroxide orally, but only under strict protocols. The dose is carefully calculated (1–2 mL per kg body weight, up to 45 mL total). After administration, the dog is walked to stimulate vomiting. If no vomiting occurs within 15 minutes, the dog is taken to a clinic. Repeated doses are not given due to the risk of gastric irritation.
Other Emetics
Less common methods include xylazine (a sedative that can cause vomiting) and sodium carbonate. These are used only in specific situations and by experienced professionals.
What to Do If Your Dog Ingests a Toxin
Follow these steps immediately:
- Stay calm and remove your dog from the source.
- Call your veterinarian or a pet poison control centre (e.g., ASPCA Animal Poison Control: 888-426-4435 in the US; VPIS: 020 7305 5055 in the UK).
- Provide information – what was eaten, how much, and when. If possible, bring the packaging or a sample.
- Do not induce vomiting unless instructed by a professional.
- Follow their advice – they may tell you to bring the dog in for decontamination (induced vomiting, activated charcoal, or gastric lavage).
Prevention Tips
- Keep all toxins (foods, medications, chemicals, plants) out of reach.
- Use childproof locks on cabinets.
- Be aware of common dangers: xylitol in gum, grapes, raisins, chocolate, and certain lilies.
- Train your dog to “leave it” and “drop it” commands.
- Regularly check your yard for mushrooms, antifreeze spills, or rodenticides.
By understanding the clinical perspective on inducing vomiting, you can make safer decisions in an emergency. Always defer to veterinary expertise – a few minutes on the phone with a professional can save your dog’s life.
