The Metrorex metro network covers four lines and 64 stations, paired with STB's dense tram, bus, and trolleybus grid. Small pets in a carrier ride free; medium and large dogs require a leash plus muzzle on the metro. Trams and buses are usually permissive at the driver's discretion. Buy a 24-hour STB pass for €2 — the cheapest big-city dog access in the EU.
