San Antonio keeps it simple but strict: dogs must be leashed everywhere in public except inside the city’s fenced dog parks, where they can run free — off-leash anywhere else can bring a fine. The crown jewel is Phil Hardberger Park, which has two separate dog parks (east and west) linked for walkers by the landmark Tobin land bridge over the highway. Don’t expect swimming — even the parks beside Olmos and Salado creeks keep dogs out of the water — and do plan around brutal Hill Country summer heat. Here are the best fenced off-leash parks in town, with the rules that actually apply, each verified against the official source.
