naughty dog

This is Rocky and you can see it in one of his dirty trick! :(
I’m really desperated on his badly behaviour, he’s destroyed the basement door!
We’ve tried to teach him good manners, but he can’t stop making pranks!
He usually spends fairly time alone till I arrive at home in the afternoon and I take him out for a walk so that, I do believe he gets bored and starts smashing things. Once he was found on the  flat roof running after a cat!!  Any advice? he keeps breaking all what he bumps into! Below you can see another photo of Rocky with my hunsband in the basement
