No brachycephalic ban or full breed ban was found on T0. What was found instead: Spanish law (Real Decreto 287/2002, implementing Ley 50/1999 on potentially dangerous animals) requires a MUZZLE (not a transport ban) for breeds classified as potentially dangerous — Pit Bull Terrier, Staffordshire Bull Terrier, American Staffordshire Terrier, Rottweiler, Dogo Argentino, Fila Brasileiro, Tosa Inu, Akita Inu — as well as for ANY dog weighing more than 20 kg regardless of breed. Direct quote: 'deberán portar bozal' (must wear a muzzle). The carrier may deny boarding if this requirement is not met, but it is not an unconditional ban — so not entered in banned_breeds (that field means outright refusal always, whereas here refusal only happens if unmuzzled). This is a Spanish legal requirement applicable to all carriers at Spanish airports, not a Binter/Naysa-specific policy.
