I agree, depends on your dog and the other dogs there, I took mine once or twice but had to stop not because other dogs picked on Eko but because he was picking on them. He does not want any doggy play dates, Xena is dog friendly but other dogs seem to be aggressive to her for some reason.
I think if you are cautious, watch out for the troublemakers at the park and your dog has a good time it's fine.
