Jack Russell Nikki tearing everything apart

Thank you for all the tips,� I learn with every newsletter and do understand some of the Jack Russel do's and dont's much better.
�
Unfortunately we need urgently tips on tearing.
�
Our Jackie - Nikki - is this September 1 year old but he tears everything apart.�He was an adorable puppy but now ........�He demolish 5 cushions already and last night was the last one.� My husband was so cross at him and slap him with 'n news paper (if he do something wrong we use rolled advertisement bulletins actually) to hit him.� It's�more the noise that scared him�than the hit on his bum. � But after this�experience Nico just want to get rid of Nikki.� �He also chewed our rattan chairs on the patio.� But this stopped a few weeks ago,�but now he tear everything apart.� (actually start costing us a lot of money - we're�thinking of�opening a check account on Nikki's name............ Nic the ripper!!)
�
He's not doing this when we are at home, just when were not there.�
�
We have another Jackie also - Sammy - she's 3 years old but has good manners - even asks you to sit on your lap.� All the things Nikki did Sammy never did.� When people tell us Jackies are busy and naughty we couldn't speak with, because Sammy did not do such things.� But boy!! - �Nikki is an understatement.!!
�
Please help!!� I need to keep Dad and the boys happy and Nikki to stay.

Kind regards
