Aggressive dogs at the park

I read some reviews saying that there are aggressive dogs at this park but I was hoping that I would have a better experience. Yesterday, I took my 5 month old puppy and she was very excited to be there until a black male dog (not sure what breed) started chasing her and humping aggressively. He was jumping on her causing her to fall on the ground. The owner was nowhere to be found. I always watch my dog when she plays because I want to make sure that she’s not aggressive with other dogs but it looks like that some owners do not care if their dog is ruining the fun. it’s a shame
