The Downey Dog Park is a mix of dirt and grass depending on how much traffic it is getting. With the dogs coming out of the pond, the soil can turn to mud quite quickly. Drinking water is also available here through a fountain, but you will need to bring your dog bowl.
You and your four-legged friend can run and play some long-range games with all the extra space, but the tree canopy might prevent fetch, or least prevent you from throwing it very far. However, if you plan on wearing a canine out, there is plenty of space and they certainly can run themselves out of steam here.
Dog bags are available, and garbage cans are abundant and emptied often. There is plenty of bench seating down the center of the dog park under the shade of the trees as well as along the fence line. It is roadside which makes this park particularly easy to get to but can be quite noisy.
The greater area of the Downey Dog Park contains a lot of other amenities. There are pavilions with shade and BBQ's spread throughout. The park also includes a public splash pad which is like a small water playground for children, with paid access for one dollar to cover the costs of maintaining.
The fence that surrounds the Downey Dog Park also separates it into two sections, one for small canines and one for large canines. The small canine section stays far more green. This section also does not have water access, so your canine is likely to leave far cleaner. Overall this is an amazing place to spend a few hours with your canine.
