I purchased three goats from out of state. We do not see too much of lung worm in our part of California, but I purchased goats whom lived right off of a creek. On and off coughing for six months. Did the basic worming when I got them home, but want to make sure I get it all out of their system. We live in a "cattle & swine" area. Most vets unsure about goats. Any suggestions would be appreciated. Better safe than sorry.
