The best place to park is in the small lot off Tenaya. And then walk down the service road to the dog park. This dog park is park of a larger recreational area. There is a skateboard area, a large open grass area, public restrooms, a small children's play area along Alexander Ave. The dog park is behind the brick building and wall of a city pump station or something.
There are three dog areas. Only two are used at a time to give one of them a chance for the grass to recover. They are long and narrow with two shade structures in each. Not surprising there isn't much shade but most dog owners hang around under the shade structures.
Two of the times we came small dogs were brought into the large dog area. The dogs were very small and I was afraid for their safety. Interesting mix of breeds. My dogs got to sniff and play and just be dogs. We stop here when we travel through Vegas or come to visit friends. My complaint is dog owners not being good neighbors...... Dog poo collection is not a priority with some owners. There is dog poo along the path to the park, on the running path and in the dog park area farthest from the entry. More poo bag dispensers on the way to the dog park and in the dog park might help this problem.
