The Russian Spaniel is a type of spaniel first standardised in 1951 in the Soviet Union after World War II by cross breeding English Cocker Spaniels, English Springer Spaniels and other spaniel breeds.
 Physically it is similar to a Cocker Spaniel, but has a shorter, tighter coat and a longer body.
 Developed and used as hunting dogs, this breed does not suffer from any major health complaints other than those normally associated with spaniels.
 Popular in its native Russia, the breed was only introduced overseas in the 1990s, and is not yet recognised by any major kennel clubs.
Ch.
 Felicity's Diamond Jim, CD, RE (June 8, 2000 – May 6, 2011), commonly known as James, was an English Springer Spaniel, best known for being the 2007 Best In Show winner at the Westminster Dog Show.
 It was his 51st Best in Show victory, and his last, as his owners chose to retire James after the win to focus him on his work as a certified therapy dog.
 He was handled exclusively by the same handler who took Ch.
 Salilyn 'N Erin's Shameless to a best-in-show at Westminster in 2000.
 In retirement he was recognised in 2008 by the English Springer Spaniel Field Trial Association for his work as a sire and has produced many champion offspring, including Ch.
 Cerise Jesse James.
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 "'Landseer" is a dog breed.
 The breed is not recognized by all kennel clubs .
 It is not to be confused with a white and black Newfoundland, which is also often called a "landseer".
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.
