With what and how often do people worm their llamas? When I got my first two the people I got them from told me to use an injectable ivermectin for cattle. Others have told me to use oral ivermectin for horses. I'm having trouble getting a straight answer on which wormers and how often, and what the proper wormer rotation would be. I rotate wormers for my horses, and worm them every four months. Same for llamas, different? I have been told ivermectin rotated with dectomax...what do all of you folks do?
