It's easy to attract an animal like that, but you'll need a little site preparation.

Has it rained lately where you live? If not, get out the sprinkler, and water well a patch of ground where you will put this trap. Then get out your spade fork and dig it up just as if you're putting in a garden. All dug up, go to your local nursery and find yourself an array of fall plants and a bag of mulch, and go plant that garden. Here's the trick: Don't put a fence around it. That dog will turn up soon enough to dig up your garden. If you're lucky, the plant roots will still hold their boxy shape from the container they came in and if they haven't been pulverized in the process you can stick them back in the dirt again after you capture Boson.
