It looks like she had a great time!
I don't know how far you were from Ft. DeSoto on the southern tip of Pinellas County, but they have the most awsome dog park & dog beach there. We are originally from St. Pete and go back to visit family - we brought Velma with once (pre Louise) and she LOVED that park.
We just do not have fenced places around here to let dogs run - the nearest dog park is a hike. Lots of open fields but too many deer and other critters to take the chance.
We will have to go. It's been years since we have been to Ft. DeSoto. I knew there was a dog park there, but as a rule we usually stay away from dog parks. Of course, the dog parks in Florida are much nicer then what I've seen in other states. The dog beach we usually go to is on Honeymoon Island. It costs five dollars per car, but it is only about a 20 minute drive from my in-laws. DeSoto is a bit further, but sounds like it would be worth the effort. Besides, I don't think we have ever done the tourist thing there with the kids. We need to do it soon as my oldest, now 14, is getting to be too cool to hang out with his parent's.

Perhaps this fall? I'm not sure if we will be down that way again before x-mas. We are trying to make our family trips coincide with dog shows for now.
