Whether or not to induce vomiting in your canine depends on what he has eaten. In some cases, it is appropriate. To safely induce vomiting, canine experts recommend that you identify the substance or material before proceeding. If you are unable to identify the substance, or if your dog is already vomiting or showing signs of respiratory distress, call your veterinarian.
When and How To Induce Vomiting
If your dog has consumed a small foreign object such as a crayon, small toy or other object that may be difficult to pass, you can induce vomiting to retrieve it.
For every ten pounds of your dog's body weight, administer one teaspoon of regular strength hydrogen peroxide (3%). Pull the liquid up into a needleless syringe or turkey baster. Open your dog's mouth and squirt the liquid as far back in his throat as possible to encourage swallowing. Your dog will begin to vomit either immediately, or within 20 minutes.
Do not induce vomiting if your dog has ingested a caustic substance.
