I know we dont really have a problem with "bad apples" because we dont have a dog park, a bunch of dog lovers get together at certain times at chosen parks to play, basicly that lady with a chow mix would not know the "play groups" existed. there is a huge park that lots of people go to at an arranged time, I love it, there is plenty of room etc.. there is another that meets between 4-6 PM in a school yard, and there is a several hundred acre farmer feild at the end of 1st avenue its so big, that many people run there dogs there, its the main place we take the dogs to run. they can disapear after a rabbit warren for several minuts we dont think anything of it, because they may disapear from sight but they have no where to go, its enclosed in 3 sides by a large creek and a high fence. so once they loose the rabbits they come runnin back, I say let your dogs play how they like, its this chow mix lady thats the stupid one.
