We use the fenbendazole horse wormer for our dogs, but it requires double strength by body weight, so need to do good research for human consumption if people go that route. NOTE: If you use it for your dogs, DO NOT use with dogs who have the MDR1 mutation, mainly herding dogs. We have to give our Australian Shepherds different meds than we do our Great Pyrenees and random mutts, who all use fenbendazole horse wormer.
