Eh. Venice might have some pit bull type dog in her and I still bring her to offleash areas. There are only a couple 'dog parks' in my city but plenty of 'offleash areas' which are usually NOT fenced (eliminates a number of dogs right there) and are designed with trails and plenty of open space. We go almost every day.
Maybe that makes me an irresponsible owner. I don't know. I used to be a super uptight pit bull person and did everything by the book, but not so much anymore. Nobody knows a dog better than its owner, who is usually going to make a decision in their dog's best interest. Yes, some people are stupid and bring inappropriate dogs to an offleash setting, but in my area these people are few and far between. If someone brings their social pit bull to a dog park I really don't care.
If it works for you and your dog, enjoy it. If it doesn't, good for you for being responsible and finding other alternatives.
As an anecdote, when I had pit bull fosters who CANNOT attend offleash parks (clause in the foster contract) I didn't go. I like to kill two birds with one stone and exercise the dogs together, so we went on leashed walks or jogs or went out in the middle of nowhere to play offleash. Venice only encountered other dogs at my work (daycare) or on leash in the street. She seemed a little more nervous and worried when meeting new dogs. Not aggressive, not reactive, nothing that made ME nervous, but I could tell she was uncomfortable. Now, since we've been back into the offleash park swing, we meet dogs casually, in a wide open space, with no pressure, greet, maybe play a bit, and move on. I've noticed she's way more relaxed and confident when greeting strange dogs now that we're back in this habit. In that respect, plus the exercise outlet, offleash parks are beneficial enough to me that they are worth the risk.
And for what it's worth, I have no problem with the dogs at the park 99% of the time. The issue I have in crowded, busy dog parks is that most people don't know enough about dogs and their behavior that they don't know when to intervene or let things be. That's more frustrating and worrisome than the dogs themselves. Most of these dogs wouldn't actually hurt another dog but because their owners don't think to call them off, they could certainly scare a more sensitive dog. Venice is sensitive, so I tend to avoid these areas and just go to quieter neighbourhood offleash parks, or trails in the greenbelt.
Sorry, that was way longer than it needed to be.
