I have found it difficult in my metropolitan area to find the dog parks. Some are run by the city, others by the state or county departments, so there is no one website. To add to the frustration the parks are regularly closed for maintenance or re-sodding around here. And on several occasions I showed up to the dog park to find it closed for its weekly mowing or flea spraying. So I started a website to catalog the dog parks near me. I found about 20 in Santa Clara county. I mapped them all and recorded the days and times they were open so I could go to the right park on the right days.
Mostly dog parks are found by word of mouth around here. Everyone seems to know about two or three of them but no one is quite sure of their names and sometimes give different directions. So I cataloged them with the park name but included the maps so I can find exactly the one I want.
