The shared rule for taking pets on public transport in Taiwan is: your pet must be inside a carrier, cage or container that meets the size limits, and its head, tail and legs must not stick out. The carrier size limits for the Taipei MRT and the High Speed Rail are both around 55 cm long and 45 cm wide, but height limits and pet stroller rules differ. Always check the operator's official website for the latest rules before you travel.
Information compiled: October 2026. Transport operators may change their rules at any time. The information below is for reference only — the operators' official announcements prevail.
