The Southeast Dog Park is comprised of grass and dirt, so canines that like to play in the water will likely leave quite muddy. There is also no running water here, so be sure to bring your own unless you want your canine drinking from the pond. They also have a water runoff drain and a small pond for canines that enjoy water features.
Doggie bags are available for those that did not bring their own, and the grounds usually stay relatively clean and although there is a lot of room there is no shade, and you are at the mercy of the Texas sun. There are no pavilions in the dog park to create shade, and the only trees they have are far too small to produce any shade themselves.
Outside of the Southeast Dog Park, the rest of the park could provide you some solace. Near the playground, some pavilions create shade, but your canine would need to be on leash in this area of the park. There are also restrooms open to the public with running water for you to hydrate your canine if you brought your bowl.
Your canine is required to be up to date on their vaccinations, and you are required to have those vaccination tags around their neck. You are not required to get a permit from the city or register your canine with the local government, so this makes for an excellent spot for visitors to come or for you to stop by on a long road trip.
