If you cannot find any other dog parks, you can put a 20 foot training lead (usually a nylon material) on her, or a 50 foot tag line (I believe this one is usually a nylon rope type, but worth it for the length). I know both are alot of line to mess with, but you would be able to take her to a city park or open field to wear her out by playing with her. Just an option....

There is a small fenced in one out by Lakeway but the small dog area is way to small. We've been going to Georgetown. Huge fenced in dog park with double entry gates. Separate small dog area although we take our small guys into the big dog area without any problem. It's near the university campus. Take University to the campus and turn left at the light.
