•Call your veterinarian or pet poison control center/hotline. Have as much of the following information ready as possible: your dog’s approximate weight, any health problems the dog suffers from, what he may have eaten, when he may have eaten it, and the amount potentially involved. If you are instructed to induce emesis at home, proceed. Otherwise follow the directions given to you by the veterinarian you have spoken with.
•If the dog has not eaten within the last two hours, offer him a small meal. This makes it more likely that the dog will vomit but is not essential if the dog is uninterested in food.
•Measure 1 milliliter (ml) of 3% hydrogen peroxide per pound of dog weight, using either the syringe or teaspoon. One teaspoon is approximately five ml. The maximum amount of hydrogen peroxide to be given at any one time is 45 ml, even if a dog weighs over 45 pounds.
•Squirt the hydrogen peroxide into the back of the dog’s mouth using the syringe or turkey baster.
•If vomiting has not occurred within 15 minutes or so, give one more dose of hydrogen peroxide measured out as described above. If vomiting still does not occur, call your veterinarian or the pet poison control center/hotline back for instructions.
•Once vomiting has occurred, collect a sample in a leak-proof container to bring to your veterinarian’s office for identification if you are unsure of exactly what your dog may have eaten.
•Thoroughly clean up the vomit. Wear latex or rubber gloves while handling vomit, particularly if it potentially contains a material that is hazardous to human health.
•Unless instructed otherwise by your veterinarian or the pet poison control center/hotline, take the dog to a veterinary clinic immediately for evaluation and continued treatment.
