I have to say that Yorkietalkjilly's idea about the umbrella is genius. I was hesitant to take Gracie to our favorite park because people there started to let their dogs off lead on occasion. The umbrella has given me the courage to let Gracie enjoy walking the shaded trails and water falls that are just a couple of blocks from where we live. It's a beautiful ideal setting that we both enjoy but I was very concerned about encountering larger dogs. So far we have had no issues but I am prepared if there is even the slightest threat!
