White Rock Lake in Dallas,Texas has over 9 miles of walking trails, many areas for your dog to swim and for you to canoe or kayak, and a wonderful off-leash area for your pooch to play. When you are done with the fun, the two of you can grab a soda or a cookie on the patio of Cafe Lago at the South end of the lake, near the intersection of Garland Rd. and Buckner.
