Calling all dog trainers!

So a few weeks ago we installed this invisible fence for our dog, Chloe. With it comes this video that makes training your dog seem really easy. Chloe first got really bored with the training, then for a while she was afraid of going anywhere near the edge of the yard, and now she just runs away! The problem is she has this thing about chasing squirrels, and there are tons of them out now collecting their food for the winter. Chloe has figured out that if she runs really fast she can get through without really getting shocked. Either that or she is so crazy about chasing the squirrels that she doesn't care. Where's the Dog Whisperer when I need him!
