Summer Streets is back from 7am-1pm on Saturday August 2nd, 9th, 16th, where the city shuts down 6.9 miles of streets from the Brooklyn Bridge to Central Park to cars, so you can walk, bike or take a stroll with your dog without any cars. It runs up Lafayette and Park Avenue.
This year they will have a special stop for dogs and their owners. The Summer Streets Dog Park at 52nd Street & Park Avenue will be up for the event, with the same rules as a typical dog park.
Here is a one page guide for the event and more information.
