I forgot to mention crate training simply because it didn't work for Tigger. I mean, he spends most of his day in the crate when we're at work, but he still makes a mess. We've been told when he's at the kennel whenever they clean up the first thing he does is remark his territory.

We did try the "free-range terrier program" one day...the day he decided to tear apart my love seat from college. We didn't really have room for it anyway.
