I don't understand people who let their dogs roam like that. Dogs running around the neighborhood can cause accidents (like what happened in this case), get hit by cars, eat things that may make them sick, potentially scare little kids etc. Plus, there's the previously mentioned issue of them going "potty" in other people's yards--yuck! Owners need to be more responsible, and hopefully the people in this case have learned that lesson and won't let this type of scenario happen again.
