Good Morning and welcome to Just answer. I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
This could be very toxic to your puppy so it is best to induce vomiting by giving him 1 teaspoon of hydrogen peroxide per 20 pounds of his weight...if he has not vomited within 10 minutes d it again. Concentrated salt water will work also.
