Our favorite Austin Dog Park would be Red Bud Isle. It is a small island in Town Lake at the base of the Tom Miller Dam. Its quite a large area for a dog park, and has plenty of space for the dogs to roam.
We used to frequent Bull Creek, but it is no longer an off-leash area at the moment.
If you on the north side of town Round Rock has a decent dog park. We now spend most of our time there, but only because it's close by and we are lazy.
+1 for Red Bud Isle (AKA Dog Park Island). Very fun and definitely different from the usual dog parks in other places (I'm originally from Southern California).
My wife and I also love to go to Zilker Park with our dogs. Nice trails and relaxing picnic areas.
Don't forget to look for the many restaurants that are dog friendly too!
