I personally think the retractable leash is a safety hazard for both the dog & those that are unfortunate enough to walk near one.It seems that "most" not all owners aren't aware of the dangers these leashes pose. I especially am concerned for the dogs that are near multi modal paths & streets. If the dog decides to bolt into an oncoming vehicle...well you get the picture.Also if the dog is at the end of the extended leash it doesn't appear to be an easy thing for the owner to retract the dog.Control seems to be an issue.maybe i'm wrong but this is just my opinion. Sorry this had to happen to your aunt.Thank God ...it could have been worse!
