RottiMommy- I have to agree with what you are saying. We have a small parking lot right out our door. Would that be a good place or is that to close to home for them? I wake up every day and ask my husband if it's Tuesday yet.
That should be fine as long as it's not a place you take your Dobie girl a lot prior to meeting the other dog. They do get to think they own everwhere they spend time. Mine think they own the whole neighborhood because thats where we walk.

Hope it helps
