I seem to be the only person in the Valley that does not love this dog park. I liked it better before it was "improved". There was more space for dogs to run and spread out. Now the park is carved up into smaller sections and very crowded. I have seen more dog fights here than in any dog park in the Valley.
I think the real problem here is the people. The same people who illegally park their rented BMWs in handicapped spots at Fashion Square bring there pit bulls and accessory dogs here and are completely oblivious when they get aggressive/go to the bathroom.
I actually saw a woman put her four year old in the park then go back to her car to get her dog. Of course all the other dogs surrounded the little guy, who was terrified. The woman had the nerve to come back to the park and yell at the people standing around for not watching her kid. (I was far enough away that she was back before I could walk across the park, but trust me, it was one of the 'What would you do?' scenarios) There also seem to be a lot of professional dog sitters who bring 5 or 6 dogs to the park and then "pretend" not to notice when the dog squats.
Long story short - in a pinch I'll go there if it's empty but I leave once the Ed Hardy crowd comes in.
