There are a few dog parks around the city but I take Layla to the one at the end of Broadway. If you're ever driving on circle by the new Stonebridge developments (with the new walmart and stuff) there's a big fenced off area with a giant hill and that's the dog park
Which part of the city are you in? I just go to that park because I'm closest to it. I've actually never tried going to any of the others!
