The dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the wolf. Also called the domestic dog, it is derived from extinct gray wolves, and the gray wolf is the dog's closest living relative. The dog was the first species to be domesticated by humans. Experts estimate that hunter-gatherers domesticated dogs more than 15,000 years ago, which was before the development of agriculture. Due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.
"Water Spaniel" (most widely accepted image of a Tweed Spaniel)
The Tweed Water Spaniel, or Tweed Spaniel, is a breed of dogextinct since the 19th century. It is best known for being involved in the early development of the modern Curly Coated Retriever and Golden Retriever breeds of dogs. They were described as generally brown, athletic dogs from the area around Berwick-upon-Tweed near the River Tweed and close to the Scottish Borders. A type of water dog, the breed was not well known outside the local area. This breed may have been created by crossing local water dogs with imported St. John's water dog, another breed which is also now extinct. (Full article...)
The Labrador Retriever ("Labrador" or "Lab" for short), is a retriever, and is the most popular breed of dog (by registered ownership) in the United States, Canada, and the United Kingdom. The breed is friendly, intelligent, energetic and good natured, making them excellent companions and working dogs.

The Kennel Club (KC) is the official kennel club of the United Kingdom. It is the oldest recognised kennel club in the world. Its role is to oversee various canine activities including dog shows, dog agility and working trials. It also operates the national register of pedigree dogs in the United Kingdom and acts as a lobby group on issues involving dogs in the UK. To celebrate its 150th anniversary on 5 April 2023, King Charles III confirmed the club with a 'royal' prefix, however until the members of the KC have voted to change the trading title to include "Royal" it will remain the Kennel Club.
The Kennel Club has four principal physical locations. Its headquarters are on Clarges Street in Mayfair, London, incorporating a private members' club (with bar, lounge, and dining facilities), meeting and conference rooms, art gallery, library, picture library, and a residential apartment for the use of the Chairman. A second site at Aylesbury, Buckinghamshire, houses the administrative offices, and charitable trust headquarters. The third site is Stoneleigh Park in Warwickshire, where the Kennel Club Building consists of a restaurant, an educational centre, and showground facilities. The fourth location is near Hexham, Northumberland, and is named the Emblehope and Burngrange Estate. It is the KC's centre of excellence for working dogs, and consists of 7,550 acres of assorted terrains including farmland (with a working farm), moorland, and woodland. A gamekeeper is employed, enabling gun dogs to engage in shooting parties, whilst the farm has a population of sheep, enabling sheepdog breeds to be trained and demonstrated. (Full article...)
