The English Cocker Spaniel is a breed of gun dog.
 The English Cocker Spaniel is an active, good-natured, sporting dog standing well up at the withers and compactly built.
 There are "field" or "working" cockers and "show" cockers.
 It is one of several varieties of spaniel and somewhat resembles its American cousin, the American Cocker Spaniel, although it is closer to the working-dog form of the Field Spaniel and the English Springer Spaniel.

 Canigou Cambrai, also known as Albert (1992–2008), an English Cocker Spaniel, is the most recent of his breed to win best-in-show at Crufts in 1996, the seventh occasion it was awarded to a Cocker Spaniel and the first time for forty six years.
 For a while he was the most successful black male Cocker Spaniel of all time in the UK, and his descendants continue to be multi-show winning champions around the world.
The American Cocker Spaniel is a breed of sporting dog.
 It is a spaniel type dog that is closely related to the English Cocker Spaniel; the two breeds diverged during the 20th century due to differing breed standards in America and the UK.
 In the United States, the breed is usually called the Cocker Spaniel, while elsewhere in the world, it is called the American Cocker Spaniel in order to differentiate between it and its English cousin, which was already known as "Cocker Spaniel" before the American variety was created.
 The word "cocker" is commonly held to stem from their use to hunt woodcock in England, while "spaniel" is thought to be derived from the type's origins in Spain.
Exquisite Model of Ware, (born 9 July 1935), was a female English Cocker Spaniel who won the title of Best In Show at Cruft's in both 1938 and 1939.
 She was the most successful female English Cocker Spaniel in Great Britain prior to the Second World War.
A Cockapoo (also known as a spoodle) is a mixed-breed dog that is the cross between either Cocker Spaniel breeds (American Cocker Spaniel or English Cocker Spaniel) and a poodle (in most cases a miniature poodle or toy poodle).
Cocker Spaniels are dogs belonging to two breeds of the spaniel dog type: the American Cocker Spaniel and the English Cocker Spaniel, both of which are commonly called simply "Cocker Spaniel" in their countries of origin.
 In the early 20th century, Cocker Spaniels also included small hunting Spaniels.
The Villanuco de Las Encartaciones (Basque: "Enkarterriko billanuko" , Cantabrian: "Villanucu", English: Little Villein of Las Encartaciones ) is a Spanish breed of dog typical of the region of Las Encartaciones (Biscay), Cantabria and northern Burgos (Spain).
The Villano de Las Encartaciones (Basque: "Enkarterriko billano" , Cantabrian: "Villanu", English: Villein of las Encartaciones ) is a Spanish working dog originated in Las Encartaciones, a comarca of the province of Biscay, in the Basque country, eastern Cantabria and northern Burgos.
 There are less than 100 of them in existence.
 The Villano derived from the Spanish Bulldog, of which it represents a lighter, faster and more agile version.
 The dog is used to catch Monchina cattle, which are raised in a feral state in northern Spain.
 The Villano is also used for boar hunting given its qualities as a catch dog.
 Males stand 60 to 65 cm at the shoulder and weigh up to 35 kg.
The English Springer Spaniel is a breed of gun dog in the Spaniel family traditionally used for flushing and retrieving game.
 It is an affectionate, excitable breed with a typical lifespan of twelve to fourteen years.
 They are very similar to the Welsh Springer Spaniel and are descended from the Norfolk or Shropshire Spaniels of the mid-19th century; the breed has diverged into separate show and working lines.
 The breed suffers from average health complaints.
 The show-bred version of the breed has been linked to "rage syndrome", although the disorder is very rare.
 It is closely related to the Welsh Springer Spaniel and very closely to the English Cocker Spaniel; less than a century ago, springers and cockers would come from the same litter.
 The smaller "cockers" hunted woodcock while the larger littermates were used to flush, or "spring," game.
 In 1902, The Kennel Club recognized the English Springer Spaniel as a distinct breed.
 They are used as sniffer dogs on a widespread basis.
 The term "Springer" comes from the historic hunting role, where the dog would flush (spring) birds into the air.
The Asno de las Encartaciones , Basque: "" , is a breed of small domestic donkey from the western part of the autonomous community of the Basque Country, in north-east Spain.
 It is named for the comarca of Las Encartaciones (Enkarterri), in the province of Biscay (Bizkaia).
 It is the only small donkey breed of Spain, and resembles the Gascon donkey, now a sub-type of the Pyrenean donkey.
 The Asno de las Encartaciones is critically endangered, and is protected by conservation measures.
