Raising my subwoofer

Newb here.  I just  bought a new  subwoofer it's like svs 2000.   I need to raise it about 8-12 inches.  Does anyone make a stand or any idea as to how make one?  The reason we inherited a dog that when we forget to crate him while we're gone, he marks when he gets anxiety or whatever his issue.  We have tried everything so here I am. 

Thanks
