It's the only fenced in dog park in Austin (to my knowledge), which is good if your dog likes to run away. It's a lot of fun when it gets really busy. At times there are more than 50 dogs and their owners in this small area, so it can get crowded, but it's alright because everyone is nice and glad you're there. Take water because there is no running water there and the dogs often run out.
Overall great place to meet people and let your dog blow off some steam and play with others.
Pros: fenced in, nice people
