My review is only for the new dog park off of Warm Springs.
I had been to the previous Sunset Dog Park once before the renovations, I was totally turned off by this trip that I never went back. Not only was the park not well kept but they people were rude and didn't watch their dogs.
This dog park has TOTALLY changed for the better since the renovations last year, it's probably the best dog park in the city. There is a enough room for the dogs to run without feeling like you can't control them if needed. There are plenty of places for dog's best friend to sit down and even a shelter over a group of tables for shade.
I have probably been to this park 25 in the last two months and have never had a problem with the people or the dogs. Everyone is friendly and picks up after their dogs. I would definitely recommend checking out the new dog park if you haven't been in a while.
