Have you visited the Round Rock Dog Depot yet?
I have just moved to north Austin and have been looking for a place to take my puppy to play. I am used to taking her to all the parks in south Austin where she can play, socialize and tire herself out. Unfortunately, the only "dog parks" I can find in north Austin are trails where there are very few other dogs to play and no fences. So, if your dog is not necessarily the best listener, then you have to keep them on a leash. My dog did not find this as fun....
But good news! For anyone living in north Austin and especially those in Round Rock who are looking for a place to let your dog have fun and play without you having to provide the action, you have a great dog park available to you. The Round Rock Dog Depot is a 1.85 acre park that is FENCED and leash free. The park is located at 800 Deerfoot Drive (behind Lake Creek Pool). If you haven't checked it out yet, I strongly recommend it. Your dog will love you for it.
Also, Parks and Recreation have been trying to think of some events to hold at the dog park. For example, a talent show, yappy hour, meet and greet, etc. I am welcome to all ideas, so feel free to share!
