A full ban (cannot fly in cabin or cargo) applies to breeds the carrier names as 'dangerous/aggressive': Pit Bull (all types), Staffordshire Terrier, American Staffordshire Terrier, Shar Pei, Boxer (all types), Bull Terrier, American Bulldog, Bullmastiff, Akita Inu, Dogo Argentino, Fila Brasileiro, Anatolian Shepherd (no exact breed_id found in the local catalog — Kangal exists but is a distinct breed, not substituted), Doberman, Rottweiler, Tosa Japonés (a close match 'tosa_inu' exists but was NOT included above due to naming ambiguity — the carrier used 'Tosa Japonés' specifically, the catalog only has 'Tosa Inu'; the match is approximate and was left out to avoid a false engine match on an imprecise id), Dogue de Bordeaux, American Akita, Neapolitan Mastiff, Presa Canario (matched to dogo_canario), German Shepherd, Mastín Italiano (matched to cane_corso — Cane Corso is sometimes called 'Italian Mastiff' in Russian; a semantic, not literal, match). Brachycephalic breeds themselves are NOT fully banned — only a signed liability waiver ('carta de deslinde de responsabilidad') is required at the counter. The same applies to a separate list of small breeds (silky terrier, beagle, bichon frise, Maltese, all Chihuahuas, toy fox terrier, poodle, schnauzer, Yorkshire terrier, dachshund) — a waiver is required, not a ban.
