I used to love running when I was young. I had a certain spot with a dog that always worried me. The same dog had bitten my grandpa while he was biking. I used to pick up a baseball sized rock at the rail road tracks for protection for the next half mile. Another dog that was on a different route was picked up by animal control. The dog's owner had a meth lab buried under the ground in an elaborate system. Made my running route there less stressful and no more carrying rocks. I would try the Columbia store... they have gear you can run in and store O.C. for the biters
