Duke Park in Troy, Ohio, is a very nice city park. It's big, over ten acres, and has nearly everything you would like to see in a park. There's a soccer field, a baseball diamond, tennis courts, over two miles of paved walking trails, a pond with a big fountain, a playground with handicapped-accessible equipment, and a fenced dog park.
The dog park section at Duke Park is big, over two acres. There's a separate enclosure for dogs under thirty pounds. Both sides of the park have metal benches, but no shelters for people. The ground in the park is covered in thick grass that the city maintains well.
And to that end, the city has provided lots of self-sealing poop bags and trash cans. The human dog park visitors are very serious about keeping the park clean and neat. But they still bring in toys to share with other canine visitors. One unusual detail of this dog park is the fact that there isn't a water fountain in the dog park itself.
There are a water fountain and a place to wash your dog just outside the inner gate of the park, on a concrete apron. There is also a bulletin board with postings for local rescue groups, training classes, and other dog info. In the summer, hot dog carts and other food vendors stroll through the park and make treats available to people.
Duke Park is nicely landscaped, with plenty of flowers and trees. The paved paths are nice and wide, to accommodate joggers, bicycles, and people with dogs. The path is largely flat, with plenty of benches and water fountains for people. Your dog is welcome on the path, provided that you're using a leash. If you do use the path, please make sure that you have plenty of poop bags and bring water for your dog.
