A Pyrantel base RFD liquid dewormer for puppies and adult dogs. RFD is for the use of removing large roundworms and hookworms. For maximum control puppies should be treated at 2,3,6,8 and 10 weeks of age. Lactating females should be treated 2-3 weeks after whelping. Dogs in an environment that can lead to re-infestation should be treated monthly. Administer 1 full teaspoon or 5mL for every 5 lbs of body weight. RFD is very palatable and is willingly licked out of a bowl. If necessary it can be placed on food. May need to repeat 3-4 weeks.
