To induce vomiting in dogs safely at home, the recommended method is using 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 the dog's body weight. This can also be calculated as 1 ml per pound of body weight, or 1 teaspoon per 5 pounds, depending on the source. The maximum dose is usually capped at about 3 tablespoons (45 ml) for larger dogs

• Administration: Use an oral syringe or a turkey baster to squirt the hydrogen peroxide into the side of the dog's mouth, between the back teeth, to avoid inhalation. Be careful not to let the dog inhale the liquid to prevent aspiration

• After giving the dose: Walk the dog around for about 10 minutes to help stimulate vomiting. Most dogs will vomit within 15 minutes. If the dog does not vomit, you may repeat the dose up to a total of 3 or 4 times, waiting 10-15 minutes between doses, but do not exceed the recommended maximum dose

• Important precautions:
  • Only induce vomiting if recommended by a veterinarian or poison control center.
  • Do not induce vomiting if the dog has ingested corrosive substances (bleach, acids), sharp objects, hydrocarbons (gasoline), or if the dog is already showing symptoms of toxicity or cannot protect its airway.
  • Avoid inducing vomiting in brachycephalic breeds (e.g., Bulldogs), cats, or if more than 2 hours have passed since ingestion

• After vomiting: Monitor your dog closely and take the vomit to your veterinarian for analysis if possible. Always follow up with veterinary care to ensure no further treatment is needed

This method is considered the safest and most effective at-home approach to induce vomiting in dogs in emergency situations, but professional guidance is essential to avoid complications
