When was first made in 1879 was Initially known as Buchanan's Blend and then House of Commons (after the British House of Commons), its nickname, referring to the black and white labelling, was eventually adopted as the official brand instead. The brand's motif (featuring a black Scottish Terrier and a white West Highland White Terrier) was conceived by James Buchanan during the 1890s.

In 1968, the Black & White brand featured in an important trademark infringement case, Maier Brewing Co. v. Fleischmann Distilling Corp., 390 F.2d 117 (9th Cir. 1968), when a brewing company started manufacturing beer under the brand name "Black and White".

After a series of mergers and acquisitions involving Dewar's (1915), Distillers Company, and Guinness (forming United Distillers), the brand is now owned by Diageo. It claims to be the most successful in France, Venezuela, and Brazil. At present, the brand is sold only outside the United Kingdom.^[1]

The Scottish Terrier (Scottish Gaelic: Abhag Albannach; also known as the Aberdeen Terrier), popularly called the Scottie, is a breed of dog. Initially one of the highland breeds of terrier that were grouped under the name of Skye Terrier, it is one of five breeds of terrier that originated in Scotland, the other four being the modern Skye, Cairn, Dandie Dinmont, and West Highland White terriers. They are an independent and rugged breed with a wiry outer coat and a soft dense undercoat. The First Earl of Dumbarton nicknamed the breed "the diehard". According to legend, the Earl of Dumbarton gave this nickname because of the Scottish Terriers' bravery, and Scotties were also the inspiration for the name of his regiment, The Royal Scots, Dumbarton’s Diehard. Scottish Terriers, were originally bred to hunt vermin on farms.

They are a small breed of terrier with a distinctive shape and have had many roles in popular culture. They have been owned by a variety of celebrities, including the 32nd president of the United States, Franklin Delano Roosevelt, whose Scottie Fala is included with FDR in a statue in Washington, D.C., as well as by the 43rd president, George W. Bush. They are also well known for being a playing piece in the board game Monopoly. Described as territorial, feisty dogs, they can make a good watchdog and tend to be very loyal to their family. Healthwise, Scottish Terriers can be more prone to bleeding disorders, joint disorders, autoimmune diseases, allergies, and cancer than some other breeds of dog, and there is a condition named after the breed called Scotty cramp. They are also one of the more successful dog breeds at the Westminster Kennel Club Dog Show with a best in show in 2010.

The West Highland White Terrier, commonly known as the Westie, is a breed of dog from Scotland with a distinctive white harsh coat with a somewhat soft white undercoat. It is a medium-sized terrier, although with longer legs than other Scottish breeds of terrier. It has a white double coat of fur which fills out the dog's face, giving it a rounded appearance.

The breed is intelligent, quick to learn, and can be good with children, but does not always tolerate rough handling. The Westie is an active breed, and is social with a high prey drive, as they were once used to hunt rodents.

The modern breed is descended from a number of breeding programmes of white terriers in Scotland before the 20th century. Cousin to the Cairn Terrier, the Westie was bred to hunt small rodents at places such as farms. Edward Donald Malcolm, 16th Laird of Poltalloch, is credited with the creation of the modern breed from his Poltalloch Terrier, but did not want to be known as such.

Other related breeds included George Campbell, 8th Duke of Argyll's Roseneath Terrier and Dr Americ Edwin Flaxman's Pittenweem Terriers. This breed of small white Scottish terriers was given its modern name for the first time in 1908, with recognition by major kennel clubs occurring around the same time.

The breed remains very popular in the UK, with multiple wins at Cruft's. It has been in the top third of all breeds in the US since the 1960s. It has been featured in television and film, including in Hamish Macbeth, and in advertising by companies such as Cesar dog food and the Scotch whisky Black & White.

Several breed-specific and non-specific health problems appear in the breed, including a condition in young dogs nicknamed "westie jaw" which causes an overgrowth of bone in the jaw of the dog. It can also be prone to skin disorders, with a breed-specific condition called hyperplastic dermatosis occurring. They are a very energetic and boisterous breed, needing regular exercise of around one hour per day.
