Responsibility...that's the key. It's beyond me why anyone would leave their dog unsupervised. People should be watching their dogs with the same diligence they do their kids. So many people arrive and seem to forget they have a pet with them until it's time to go. Once it starts getting busy wherever we end up, unless we know a majority of the people there, we have a 30ft lead that we attach her to. Did the owner of the little dog have a leash? I'm asking only because I've had Emmy on her lead taking a walk several times at Hidden Shores, and I can't tell you how many "little" dogs, unleashed, run out from trailers and start barking and snapping at her. A few seconds later the owners run out to snatch them up, always with a quick "sorry." As a puppy, she always assumes they want to play with her; this may not be the case as she gets older...I dunno. It seems that always the little dogs in the park are the ones to be aggresive. Just an observation. It would be horrifying to watch any dog/pet be killed, hurt, etc. I just feel that 99% of the time any issues can be resolved by responsible owners.
On another note, are you going to be out on the 4th?
