To make your dog throw up safely in an emergency, the recommended method is to use a 3% hydrogen peroxide solution. Here is how to do it properly:

• Dosage: Give 1 teaspoon (about 5 ml) of 3% hydrogen peroxide per 10 pounds of your dog's body weight. Some sources suggest 1 teaspoon per 5 pounds, but the 1 teaspoon per 10 pounds dosage is commonly accepted and safer to avoid overdose

• Administration: Use a syringe, turkey baster, or dropper to administer the hydrogen peroxide orally. Be careful to avoid inhalation to prevent choking or aspiration

• Wait and observe: Your dog should start vomiting within 10 to 15 minutes after administration. If your dog does not vomit within this time, you may repeat the dose once or up to three times total, waiting 10-15 minutes between doses, but do not exceed three doses

• After vomiting: Keep your dog in a comfortable, easy-to-clean area. Monitor for any signs of distress or continued vomiting and contact your veterinarian immediately after vomiting occurs

• Important precautions: Do not induce vomiting if your dog has ingested corrosive substances (like bleach or drain cleaner), sharp objects, hydrocarbons (gasoline), or if your dog is already vomiting, unconscious, or has certain health conditions (e.g., brachycephalic breeds)

. Always consult a veterinarian before inducing vomiting.

Inducing vomiting can be dangerous if done incorrectly, so it should only be done when advised by a veterinary professional or in clear emergency situations such as ingestion of toxins like rat poison or chocolate

. In summary, the safest at-home method to induce vomiting in dogs is 3% hydrogen peroxide at about 1 teaspoon per 10 pounds of body weight, given orally, with careful monitoring and veterinary consultation
