How do i train my pig to behave well?

i got a tecup pig named pickles. he is about six months old. he's been behaving badly. he knocks over the garbage can, and gets into anything he can. he will go outside to the bathroom but only if i force him to go out. he won't responde to a comand. i would also like to train him to go and lye down on command too. please help so he can be a better behaved pig. i would also like some recomendations on some toys that'll keep his attention.
