To safely make a dog throw up at home, the recommended and safest method is to use 3% hydrogen peroxide, but only if a veterinarian or poison control center advises it. Here's how to do it properly:

• Dosage: Give 1 teaspoon (5 ml) of 3% hydrogen peroxide per 10 pounds (4.5 kg) of the dog's body weight, not exceeding 3 tablespoons in total

• Preparation: If possible, feed your dog a small meal first (e.g., canned food or a slice of toast) because food can help stimulate vomiting and make it easier for the dog to expel the contents

• Administration: Use a syringe (without a needle), eyedropper, or turkey baster to squirt the hydrogen peroxide into the back of the dog's mouth, aiming to the side to avoid choking. Wrapping a towel around the dog's neck can help manage drips and mess

• Aftercare: Encourage the dog to walk around gently for about 10 minutes to help mix the peroxide with stomach contents. Vomiting usually occurs within 10 to 15 minutes. If the dog does not vomit, you may give one more dose but no more than twice

• Important warnings: Never use other substances like syrup of ipecac or salt, as these can be harmful or toxic. Do not induce vomiting if the dog has ingested sharp objects, corrosive substances, or if the dog is unconscious, having seizures, or having trouble breathing. Always contact a veterinarian before attempting to induce vomiting

• After vomiting: Monitor your dog closely and contact your vet for further advice or treatment. You may need to collect a vomit sample for the vet to analyze

This method is effective for recent ingestion (ideally within 2-3 hours) of certain toxins such as antifreeze, chocolate, grapes, or rodent poison

. In summary, the safest home method to induce vomiting in dogs is administering 3% hydrogen peroxide at the correct dose under veterinary guidance, followed by careful monitoring and veterinary follow-up
