If you are also treating tapes I would like to suggest using moxi with prazi once a month and a follow up with a 5 day10 mg per kg of fenben 2 weeks after moxi/prazi is taken. Or 1 dose of moxi plus prazi (nothing else) for several months and this should tremendously lower or eliminate most tapes and roundworm infections. Any tetracycline product should eliminate any bacterial infections that may arise . Adding fenben as mentioned above will also target some tapes and flukes , it also keeps fungal infections in check.
