Make sure the dog knows what you are wanting him to get on. By this I mean show him a few pigs and get him interested in them. If he is a young dog and hasn't seen many pigs then be careful using an e collar on him to break him right now, you may just make him not want to hunt at all if your not careful. JMO
x2, pup needs to know it is ok to be in the woods first as well as it is hog you want...before e collar...
