Happy Jack ProPup Chewable Wormer Caution

For use only as directed below

ANADA 200-281 Approved by FDA

DIRECTIONS FOR USE: For the removal of large roundworms (ascarids) and hookworms, give 1 flavored tablet for each 10 lbs of body weight. (Dosage is designed to provide at least 2.27 mg per pound of body weight for dogs weighing over 5 lbs., and at least 4.54 mg per pound of body weight for dogs weighing 5 lbs. or less). For dogs weighing more than 10 lbs, flavored tablets may be broken in half to provide 1/2 tablet for each additional 5 lbs. body weight. The presence of these parasites should be confirmed by laboratory fecal examination.

Offer the proper dosage by hand or in the dog’s food container, with or without food. Do not withhold food from your dog prior to or after treatment. A follow-up fecal examination should be conducted in 2 to 4 weeks after first treatment to determine the need for retreatment.

Since anthelmintics cannot be relied upon to prevent reinfection or to remove larvae not present in the intestinal tract at the time of initial treatment, for maximum control, it is recommended that puppies be treated at 2, 3, 4, 6, 8, and 10 weeks of age. Lactating bitches should be treated 2-3 weeks after whelping. Adult dogs should be routinely treated at monthly intervals to protect against environmental T. canis reinfection. Retreatment of adult dogs may be necessary at monthly intervals as determined by laboratory fecal examinations or in animals kept in known contaminated quarters.
