The problem is, that nothing is licensed for goats, so we have to use sheep medicines etc. I have an awful problem at the moment with Cain and Abel. Never had a worm problem in all the years we have had them, but the vet thinks they have a parasite problem - or liver damage. Anyway, I have come to the conclusion that my dosage of panacur has not been enough, they are big tall boys. Poor boys have had sheep pour on, and all sorts over the last couple of weeks, so hopefully back on track. That has taught me to make sure they get enough wormer in future.
