Talk to your local animal control officer. They will assure you there are 'bad' dogs that no amount of training can help. (like phat....imagine 4 phats, off leash...lord help us.)
Again, this tread was about multi-big-off leash dogs and owners who clearly indicate they are the only ones entitled to the planet. So far, no responders to this thread would be considered that type of person.

Bad dogs....my next door neighbor has a large, mean looking pit-bull (i don't understand the the popularity of those dogs) who cowers at the sight of my little fearless kitty. It's just a big goofy dog that 'looks' mean. The same neighbor just gave away two other pits because they were "bad" dogs and couldn't be trusted. These dogs would try to crash through the wood fence and 'get' anybody walking by.

This guy has a toddler and one on the way. He NEVER hikes my park with the dog unleashed, goofy dog or not, because the signs say to, and doesn't want to lose the dog in the forest.
