Is A Sullivan's off-leash?

Yes. Dogs run off-leash throughout the park, with no separate on-leash section.

The park is fully fenced, which keeps the compact off-leash space secure without an easy exit to the surrounding residential streets.

How busy does it usually get?

Expect a quiet, low-key scene rather than a crowd. The park draws mostly neighborhood regulars, so visits tend to stay calm.

Is it a good fit for small dogs?

The compact size suits small and socially confident dogs. It is a single shared space rather than separate small- and large-dog zones, so plan for one open area.
