You need to train him as to who's boss, and quick while he's still young, I make my young boar 'wait' by his feeding pallet, this was by pointing and saying 'go on' when I arrive with food, open the gate to enter, as soon as he comes to me I say 'No' and 'go on' until he gets the idea, he now waits for me! its a usefull tool when you simply dont want to 'play'! be very careful with children (personally I dont allow children in with him now) they and you can get torn by his tusks simply by him brushing past you! never underestimate him and always respect the fact that he is a boar. always have an easy escape and dont take him for granted! may sound a bit OTT but boars can be very dangerous when you least expect it!
