Boston plays it strict: dogs are leashed almost everywhere by default, and off-leash life runs on two tracks. The dependable one is the city’s fenced “Dog Recreation Spaces” and the Cambridge and Somerville dog parks — off-leash all day inside the fence. The other is time- or place-limited: Boston Common’s off-leash zone moves to a different signed lawn each day, Brookline’s Green Dog parks are off-leash only mornings, and Cambridge’s Fresh Pond is off-leash all day but only with a visible city license and real voice control. Here are the spots that are genuinely official, with the rules — and the licenses — that actually apply, each verified against the source.

South End / Back Bay · Carleton St at Southwest Corridor Park, Boston, MA 02116
A fenced off-leash dog park in the state-run Southwest Corridor Park, tucked along Carleton Street between Braddock Park and Holyoke Street — benches, shade and a seasonal canine water fountain.
Dorchester · 92 Mt Ida Rd, Dorchester, MA 02122
A City-designated off-leash Dog Recreation Space in Dorchester's hilltop Ronan Park. Off-leash is allowed only within the designated space; the rest of the park is leash-only.
Downtown / Beacon Hill · 139 Tremont St, Boston, MA 02111
Boston Common offers off-leash access on designated lawn parcels that rotate to protect the turf, run by the Friends of the Public Garden's Common Canine program with Boston Parks. There's no fence — off-leash is allowed only where the signs are.
Neighborhood Nine · 99 Sherman St, Cambridge, MA 02140
A dedicated off-leash dog area near the New Street entrance of Danehy Park, Cambridge's largest park. Off-leash all day within the dedicated space — no morning-only restriction.
West Cambridge · 250 Fresh Pond Pkwy, Cambridge, MA 02138
A 162-acre reservation around Cambridge's drinking-water reservoir where dogs may be off-leash all day — but only under strict criteria. It's a shared-use trail, not a fenced run, so genuine voice control is required.
South Brookline · Newton St, Brookline, MA 02467
Brookline's Green Dog program allows off-leash hours at the top of the hill (Avon Street side) of Larz Anderson Park. Off-leash is morning-to-early-afternoon most of the year, extending to dusk in winter.
