There are plenty of benches for the humans to sit and chat, and often people walking through Union Square Park will stop and look at the dogs playing. There are also lots of trees for shade on those hot summer days. The park provides water for your dog to stay hydrated and pools in the warmer weather to splash around if he wants.
When winter rolls around, bring your own supply of water just in case it is not available. Garbage cans are located at the gates and poop bags can be found along the fence. However, if the empty bags need to be replenished or you want to get Fido a toy after you're done playing, Petco is on the other side of the park. When your dog is not in the fenced in area, he must be on a leash.
Like all New York City parks, make sure your dog wears his collar with ID tag and rabies vaccination tag. Your dog must respond to your call and not chase animals like squirrels or birds. Be sure to monitor your dog and discourage barking, especially in the morning or evening. If your dog leaves the fenced-in area, he must be on a leash no longer than six feet. To get to the dog run, go to 15th Street and Union Square West.
