Got Pepperoni

It is not easy to train for a marathon and I give anyone credit for doing it. My poor friend D has a fear of dogs and is training for a marathon. She has now found her great 5 mile loop has a dog that is not chained, or held back in an manor and likes to come after her. She gets very nervous and her heart starts pumping hard (like it isn't already but that's another story).

On occasions that M runs with her, M brings pepperoni sticks in hopes that she can than throw at the dog and he will chase and eat it and leave them alone. I don't think she's actually used it yet. I hope she never gets to that point.

Today D says she got chased by a dog - it is not easy to be a runner and have to deal with animals that allowed to rome like us humans. I do believe it is better now than it used to be years ago (when I was young - yes that was years ago). So any suggestions to prevent from major scarring on legs from animal teeth marks - other than the pepperoni?
