The Kerry Beagle is one of the oldest Irish Hounds, believed to be descendant from the Old Southern Hound or Celtic Hounds, detailed pedigrees date back as far as 1794. Originally bred as a scent hound used to track game, larger hounds were then sent in to do the actual hunting.

The Kerry Blue Terrier is a breed of dog. In Ireland it is often called the Irish Blue Terrier. Originally bred to control “vermin” including rats, rabbits, badgers, foxes, otters and hares, over time the Kerry became a general working dog used for a variety of jobs including herding cattle and sheep, and as a guard dog. Today the Kerry has spread around the world as a companion and working dog. Despite winning Crufts (the most important UK dog show) in 2000, it remains an unfashionable breed, still distinctly uncommon, but not as threatened as some of the other terrier breeds such as Skye Terrier, Sealyham Terrier, and Dandie Dinmont Terrier.

The King Charles Spaniel (also known as the English Toy Spaniel) is a small dog breed of the spaniel type. In 1903, the Kennel Club combined four separate toy spaniel breeds under this single title. The other varieties merged into this breed were the Blenheim, Ruby and Prince Charles Spaniels, each of which contributed one of the four colours available in the breed.Thought to have originated in the Far East, toy spaniels were first seen in Europe during the 16th century. They were made famous by their association with Charles II of England (1630–1685) and have been linked with English royalty since the time of Mary I of England (1516–1558). Members of the breed have been owned by Grand Duchess Anastasia Nikolaevna of Russia, Queen Victoria and Elizabeth II.The King Charles Spaniel and the other types of toy spaniels were crossbred with the Pug in the early 19th century to reduce the size of the nose, as was the style of the day. The 20th century saw attempts to restore lines of King Charles Spaniels to the breed of Charles II’s time. These included the unsuccessful Toy Trawler Spaniel and the now popular Cavalier King Charles Spaniel. The Cavalier is slightly larger, with a flat head and a longer nose, while the King Charles is smaller, with a domed head and a flat face.Historically the breeds that were merged into the King Charles Spaniel were used for hunting; due to their stature they were not well suited. They have kept their hunting instincts, but do not exhibit high energy and are better suited to being lapdogs. The modern breed is prone to several health problems, including cardiac conditions and a range of eye issues.

The Koolie is a working or herding dog which has existed in Australia since the early 19th century when it was bred from imported British working dogs.There is substantial variation in the Koolie population, as Koolies were bred to exhibit different characteristics in different regions. The Koolie Club of Australia defines the breed based on its ability to work rather than on its Conformation show. However, most Koolie breeders refer to the Koolie as a breed rather than as a type, and assert that it “breeds true”, with various types or strains.The Koolie is a ‘heading dog’, one which has a natural instinct to cast out (i.e., circle widely), round sheep and bring them back to their owner. Koolies are known as silent, upright, working dogs. They are used for “heading” sheep and also for quiet careful work at close quarters at lambing time or for “shedding” (cutting out) sheep.
