Starting a pup by its self

I like to start pups on a piglet that they can easly whoop and slowly move them up to a pig that will thro them off. In my opion if a pup gets jacked up to young it can set them back but not always that why I think it's confidence is most important when they are young. I use to work the pen but got away from it. I think the more time you spend with that pup the better it will only help you as a team cuz you will know him inside and out. I like to stake a pig out in the woods walk them few hundred out and set and watch they will pick it up then they know right off that woods equals pigs lol
