Wow 53 acres of fenced dogpark sounds amazing! The biggest we have been to is in Jacksonville, FL, and is about 25 acres. It seems huge, with ponds, a wooded area with trails, big open fields for ball tossing. I hope you have a wonderful time!
Some dogparks are wonderful, some downright dangerous. Depends on the people as well as the dogs. It can vary by time of day, a rough crowd may come in the mornings, and a more mellow crowd in the evenings, or on weekends.
We are so lucky to have several small ones near us, and one "big" 6 acre park where we meet the basenji gang on Sundays. We had 14 basenjis today, 17 last Sunday, and it was fun for everyone. I have seen bad things happen, thankfully not often, you have to really pay attention not only to yours but to other people as well. And if you ever get a bad feeling….LEAVE ASAP !
Overall I am a big fan of dogparks, though mine mainly lie around and don't participate in too much of the running and chasing, with the exception of Eddie and squirrels!
