When is a Walk nota Walk?

The answer is when you are walking with Maggie our Springer Spaniel. We have been working on Maggie walking by our side. I have been having better walks walking down the street in front of our house but it is not a very long walk. Most of the snow has melted because of the rain and warmer weather so this morning I decided to try walking in the back of our lot to the church and school. I walk around the soccer field twice. First there was some snow left. Then we[Maggie and I] saw the rabbit hop in front of us. Maggie wanted to pull me after the rabbit but I managed to stay on trail. We had just began the trip around the field when her leg got tangled in the leash. I reached down to untangle her and she pulled the leash out of my hand and off she ran. After all the practice of come when I call went out the window. She paid no attention to me. I know not to run after her because she will run away faster than I can catch her. So I continued walking as I was still walking her. She ran far beyond our usual path but she kept me in sight. She stopped to examine some dead plants in a garden and I was able to grab her leash. What I learned from the walk is that there is a lot of work to do. My fear is there is an express way near by and she will run onto it.
