lung worm

panacur 5 day guard is a good one you have to give it over 5 days and its liquid..i had a mare that used to be in with donkeys on occasion so needed to worm her more regularly as donkeys carry the worm.the worm can stay dormant in your field as larvae for 5 years! so make sure the field is cleaned and you are very vigalent with the worming!
