I know a few places in Austin, depending on what you guys are wanting in a dog park. We only have 2 off-leash dog parks that are completely fenced in. The main one is off Riverside and 35 and really crowded and not too fun. I do know a GREAT park where I take my dogs a lot. It isn't fenced in, but there is a creek and some steep slopes blocking the way to the road so the dogs can't get over there. But that might not work too well for all of us. I'm not sure how everyone's dogs are.

There is also another park where I've taken Reece (before I got Lolly). It is huge. Its more like a place where you can go to hike. The whole thing is surrounded by a fence, but its so big that if someone's dog took off, they might get lost. There's a really pretty picnic place there.

I have a book filled with places to take your dog all over Texas. I'll look up the places in Austin/Dallas areas.
