I have always used the same wormer I do for my mini horses: either strongid or ivermectin according to weight. I have a little 6 month old jennet that was just wormed along with my mini horses with zimectrin to make sure you get rid of those nasty bot worms. I worm every 8 weeks; rotating my wormer. I know alot of folks are worming with the zimectrin gold, but so far we don't have any problem with tapeworm, so I haven't paid the extra for the gold. What color is your little guy?
