I need to use-or-lose 30 days of vacation by the end of the year and have no idea what to do. I've never taken a vacation before but want to get out of the city. Can anyone recommend dog-friendly activities or locations within a few hour's drive of Pittsburgh, preferably leaning towards cheap?

We both hate crowds, and I'm scared of hiking trails because irresponsible dog owners tend to leave their dogs off leash. I don't drink alcohol so breweries/wineries are out.

So far the only thing I've come up with is taking a weekend fishing trip to Ohio.
