Stay away from this park. The dogs that frequent this park belong as extras/stand-ins for Cujo.
I left Washington Park when I moved to be closer to school and this little park was my only closest option. My dog was never aggressive until she had to defend herself here. All the dogs swarm to the gates when you come (a behavior that makes the incoming dog extremely nervous even aggressive), the owners don't pick up after their dog with the excuse that there are no bags provided, there is no little/big dog separation, and most of the dogs aren't trained to even come to their owner in case of an event. It's like a meth lab waiting to explode.
On a busy night, you can literally walk in and feel the tension between the dogs. My last time there, it was extremely busy but I still let my dog in because she's never had any problems before. All the dogs teamed up and chased my 90lb baby the moment she got in and the owners (mostly college students) literally just stared dumbfounded and watched until she snapped back to defend herself. Then I was the one being glared at and given the stink-eye like it was my fault.
I'm sorry, I didn't know I just stepped into Michael Vick's backyard by accident instead of the dog park.
I had to re-socialize my dog at one of the fancy, for-rich people indoor doggy daycare (thank heavens for Groupon) and finally, 1 1/2 years later, my dog can finally step foot in a dog park. She's still prone to ignore other dogs and doesn't tend to be very social with the dogs in the park, but it's a step in the right direction. Wish I had never gone here.
