People tend to check in during these times:
Doggie pools and water bowls are available at the park. Bring your own tennis balls!
Cool for the dogs not for the humans on a hot day.
Great secret entrance for this dog park at 60th and York. It's a ramp closed to cars, but works for runners and people to get to the river walk - it will save you going the long way at 63rd.
Usually pretty crowded but it's a very nice location next to the river.
The park is accessible at 63rd & York, over the pedestrian bridge. They have separate runs for large and small dogs, and there are even paddy pools! Great way to keep your pup cool on a hot day!
