Alano Español or Spanish Alano (English: Spanish Alaunt) is a large breed of dog of the molosser dog type, originating in Spain. The dogs have been used as cattle catch dogs, hunting, and guarding. The breed is also known for its former use during Spanish bullfights, and is sometimes called the Spanish Bulldog in English.
Large dogs that are similar in appearance and may share the history of the Alano Español include the molossers of the Canary Islands such as the Dogo Canario (Perro de Presa Canario) as well as the Mastín Español (Spanish Mastiff) and the Dogo español (Spanish Dogo). Among some of the South American breeds, descended from these dogs after brought by the Spanish explorers and conquistadores are Cimarron Uruguayo, Dogo Argentino, the extinct Perro de Pelea Cordobes and possibly, the Fila Brasileiro.
The Alano Español is a very large dog of the Molosser type, with a large, strong head. Males should be no smaller than 58 centimetres (23 in) at the withers, and should weigh 34–40 kilograms (75–88 lb) with females somewhat smaller.
The coat is short and thick but never velvety, and is most often a brindle of any color; leonardo (fawn);black and brindle; sable wolf. White chest flashes are acceptable but prevalence of white is not. The face may or may not have a black mask.
The head is the shape of a cube and is brachycephalic. The muzzle is short with the lower jaw slightly concave, and has a very large, broad, black nose. The ears are set high and may be drop or cut short. The skin is very thick, with neck folds and some wrinkles on the face.
Despite the sometimes used English name, the Alano is not a bulldog: it should never have a flat muzzle or show signs of prognathism. The cranio-facial proportion should be 65:35, meaning a significantly longer muzzle than for instance the Boxer has.
No record or history of health issues in the breed.
Since the breed was used for hunting in packs, it is very sociable with other dogs. All large dogs must be well socialized with humans and other animals when young, if they are to be safely kept as pets. Large working dogs, such as the Alano Español, need regular training and activity all of their lives.
