Yes - I think they are hard on people with multiple dogs -
Course with Keegan's hips I don't visit it near as much as I used to - she's content to run around my yard or my parents yard - I don't have to wear her out as much as when she was a pup. But I wish they would put a sign that said if you want to play ball or whatever go to the open areas outside the dog park - that drives me NUTS when kids are running around playing ball etc - and then the dogs are getting excited and stealing balls - etc.
Course some people don't have enough common sense to fill a thimble so why am I surprised....
