A follow up fecal examination should be conducted in 2-4 weeks after first treatment to determine the need for retreatment. Nursing 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. |
