We recommend asking your veterinarian concerning for your dog's health, and reaching out to the manufacturer directly for clarification regarding follow up doses of RFD Liquid Wormer or other product questions not addressed on the label. Zoetis can be reached by either calling 888-963-8471, or by visiting their website's contact page here.
