I've only had them a week and a half and the vet said they must have gotten it from the pet shop they're in anyway he told me to give the ivomec every 10 days. First day is 0.01 ml. 10 days later 0.02 ml and 10 days later 0.03. Then go back to him and see if the lice is gone. That seems like it's not enough to do anything. Has anyone else's pigs been prescribed this medicine and that time line? I feel like it isn't enough. Also is there anything I can do in the mean time to help with the itching? A shampoo,cream or flea brush ? By the way the both weigh 0.6 lbs each
