Dixie Belle,

I would search for Pet Friendly hotels first. You need to make sure that your pup has a place to sleep. I always use TRAVELOCITY. It allows you to select your options and one of the options is Pets Allowed! Travelocity.Com

After you have a hotel, you can look for attractions and events. If all else fails, have you considered a camping trip? You could rent an RV if you don't like roughing it. But if you are the outdoors type, you can pack up your tents and sleeping bags and head out to the great outdoors. Your dog will be able to run around sans leash and you will all have a great time. Just a thought.
