The Löwchen or Little Lion Dog (German: "Löwchen" "little lion," French: "Petit chien lion," "little lion dog") "is a breed of dog.
 A small dog, they are considered by some registries as a toy dog and by the American Kennel Club as a non-sporting dog."
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.
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 Non-Sporting Group of dogs is a kennel club dog breed Group designation.
 How "Non-Sporting" is defined varies among kennel clubs, and different kennel clubs may not include the same breeds in their "Non-Sporting Group".
 Some kennel clubs do not use the "Non-Sporting" classification.
 "Non-Sporting Group" is not a term used by the international kennel club association, the Fédération Cynologique Internationale, which more finely divides its breed groupings by dog type and breed history.

 My Own Brucie (May 4, 1935–June 9, 1943), was a male American Cocker Spaniel who was the Best in Show at the Westminster Kennel Club Dog Show in both 1940 and 1941.
 He was sired by popular sire Red Brucie and died as a result of a kidney and liver ailment.
 Obituaries described him as the most photographed dog in the world.
The Welsh Springer Spaniel is a breed of dog and a member of the spaniel family.
 Thought to be comparable to the old Land Spaniel, they are similar to the English Springer Spaniel and historically have been referred to as both the Welsh Spaniel and the Welsh Cocker Spaniel.
 They were relatively unknown until a succession of victories in dog trials by the breed increased its popularity.
 Following recognition by The Kennel Club in 1902, the breed gained the modern name of Welsh Springer Spaniel.
 The breed's coat only comes in a single colour combination of white with red markings, usually in a piebald pattern.
 Loyal and affectionate, they can become very attached to family members and are wary of strangers.
 Health conditions are limited to those common among many breeds of dog, although they are affected more than average by hip dysplasia and some eye conditions.
 They are a working dog, bred for hunting, and while not as rare as some varieties of spaniel, they are rarer than the more widely known English Springer Spaniel with which they are sometimes confused.
The Cavalier King Charles Spaniel is a small spaniel classed as a toy dog by The Kennel Club and the American Kennel Club.
 It originated in the United Kingdom and is one of the more popular breeds in many countries.
 Since 2000, it has grown in popularity in the United States and ranks as the 18th most popular pure-breed in the United States (2013 Registration Statistics).
 It has a silky, smooth coat and commonly a smooth undocked tail.
 The breed standard recognizes four colours: Blenheim (chestnut and white), Tricolor (black/white/tan), Black and Tan, and Ruby.
 The breed is generally friendly, affectionate and good with both children and other animals; however, they require a lot of human interaction.
 Since they are a family dog, it is recommended to not leave them alone for long periods at a time.
 The expected average lifespan of a Cavalier King Charles Spaniel is under ten years.
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).
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.
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.
