There are a few benches for seating located along the fenceline. One large tree stands in the middle of the dog run and provides a great deal of shade during mid-day. The ground here is not well maintained, and the grass has died, leaving dirt in its wake. Your canine will likely leave pretty dirty. On a rainy day, this dirt will turn to mud and your cleanliness troubles compound.
There are no structures to provide shade or protection from the elements, but the tree does protect you from the elements decently in the spring and summer months. Eisenhower Park, the park that surrounds the dog park, is rather lovely. Pavilions are around with picnic tables underneath.
There are large playgrounds for children, public restrooms, and a lakeside section. However your canine is allowed in some of these areas, they are required to remain on the leash anytime they are outside of the fenced dog park. The park also hosts a ton of activities and events in large fields. Information regarding these activities can be found on the city parks and recreation website.
The Eisenhower Dog Park has beautiful vegetation and beautiful views throughout, but the dog park is not up to par. If you are a local in the area, this dog park is an excellent resource for you in a pinch, but non-residents and travelers can do better at other parks nearby or on their travel route.
