Western Gateway Park is dog friendly with lots of on-leash walking trails and open space. Doggie bag dispensers and trash cans are located throughout the park. But the dogs and their people really enjoy socializing at the off-leash dog park.
To get to the dog park, use the west driveway (on the other side of the Disc Golf course) and follow the driveway to the parking lot. There is handicapped parking, drinking fountain and bathroom (vault toilet) available at the dog park.
The dog park has three sections. The east and west sections are approximately 12,500 sqft and can be reserved like all other park amenities. When not reserved, you can choose whichever section you want, but if you see only small dogs in the right or middle section, then do ask if the small dogs are OK with a larger dog in their midst. The fence around the perimeter is 5' tall. The fence around the observation area is only 3' tall. Some dogs are able to jump over. All sections have a hose bibb to fill water bowls. In the summer you may fill a small kiddie pool to let your dog get wet and cool off.
If you don't see any dogs, then try a cooler time of day in the summer, or a warmer time in the winter. Small dogs frequently meet on Saturday mornings at 11am when the Chihuahuas Meetup at the Park.
