Why does my dog keep destroying my house when nobody is home?
	
	
		I got a Lab mix at the end of June.  He only did a couple of minor things wrong in the beginning but considering he is around 1 year and was not trained properly, I just kept training him with no.  He also humps my other male dog, but only when I am not around.  When I leave, he will chew up paper, pee all through my house and poop everywhere.  The pee can start at the top of the stairs and go down the stairs through the living room, dining room, and the kitchen.  The previous owners gave me a cage, which he destroyed, so I got a metal crate.  Unfortunately, my 40-lb dog chewed up the bed in there, ruined the liner, and banged against the door so much he broke it and got out.  So, when I got home the cage was broken and he again peed and pooped everywhere.  I praise him and award him when he goes outside, I take him out before I put him in the cage and awarded him when he went in the cage, so what am I doing wrong?  Also, when he goes in the house I mix bleach and water and mop the whole house since I have hardwood floors.  Usually my brother is home with him so he does not have to be put in the crate, which I do not even have that option since he ruined both cages, but he cannot be trusted to run the house like my other dog.  What other options can I try?
