Door vs wall vs sliding
Door-mounted is the common pick — cut a hole in the door, install, done. Wall installation costs more but keeps the door intact and lets you put the flap at dog height. Sliding glass inserts need no cutting — the best rental option. Smart doors lock by chip — the security pick.
