My little Yorkie has become a fan of chewing our cabinet corners too and so far the only thing that's stopped her is Nature's Miracle Best Behavior Pet Training Aid. Be super careful with it though, it's really really strong... one whiff and it will have you coughing and hacking like crazy. I made the mistake of spraying a ton of it on the carpet back when Tuffy was chewing on it and both of us were sneezing and coughing for days before the stuff wore off. It only takes one spray to do the trick.
