British Milk (sheep): The British Milksheep originally was known as the Alderbred and is a breed of domesticated sheep developed by Lawrence Alderson in Wiltshire and Northumberland.  It was exported to several countries including Hungary, France and Greece, and from there other neighbouring countries.  It now can be found mainly in the UK, Hungary and Canada, although the population in Britain was decimated during the outbreak of foot-and-mouth disease in 2001.  The exact composition of the breed has never been declared but it was based on high-performance animals in existing flocks of Dorset Horn, Bluefaced Leicester and Eastrip Prolific sheep kept by the Alderson family.  Additional individual animals were selected from Lleyn, Texel and East Friesian breeds.  Subsequent selection was based on measures of productivity, without regard for uniformity of appearance.  A standardised breed type emerged gradually as the blending process continued.  The animals were exposed to rugged conditions in the upper Pennines in northern England to develop robustness and adaptability.  Progeny testing from the initial stages laid the foundation for continuous genetic improvement.  Initially, total ownership of females of the breed was retained by the family and only rams were sold, but groups of females were released to other breeders in 1981.  Numbers of flocks and animals increased rapidly and there were more than 5,000 breeding ewes by the mid-1980s with flocks widespread in Britain.  A flock book was published in 1986.  As the name of the breed suggests, it is a prolific milk producer, and several large dairy flocks were established.  However, it is a robust, general-purpose sheep rather than a specialist dairy breed.  It is known for its extremely high prolificacy, and rams are used to sire high-performance crossbred daughters.  The quality of its carcase and wool are extra beneficial traits.  In all countries outside Britain, the British Milksheep is used more as a dairying breed with dual-purpose qualities, but it is used also in most countries as a crossing sire; in Britain on hill and longwool breeds, in France in the Alps and Pyrenees on mountain breeds, in Greece on Chios dairy ewes, and in Hungary on the predominant Merino population.  In France it has contributed to the development of the Boulonnais breed.

Vatra (Slovak magazine): Vatra was a Slovak magazine.  Published monthly after war by Slovak emigrants in Great Britain in years 1948–1952.  Originally papers of Slovak Youth in Great Britain, Vatra brought to its readers as many news from the home country as could gather, and also some announcements of activities by various groups of our countrymen in England and elsewhere in exile.  All 1948 - 1952 issues are held in British Library.  Today's "Vatra" is published on Internet with articles mainly on Slovak history.

Slovak White goose: The Slovak White goose (Slovak: "Slovenská biela hus") is a breed of domestic goose originating in Nitra in Slovakia.  The Slovak White goose is an autochthonous breed of Slovakia.

Slovak Cuvac: The Slovak Cuvac is a Slovak breed of dog, bred for use as a livestock guard dog.  This mountain dog—also known as Slovensky Cuvac, Slovak Chuvach, Tatransky Cuvac and Slovensky Kuvac—is closely related to the Hungarian Kuvasz.  The alternate German and English spelling "Tchouvatch" reflects the pronunciation: "chew-votch".  The breed is recognised under sponsorship from Slovakia by the Fédération Cynologique Internationale with the name Slovenský čuvač.  Despite the multiple renderings in English, these refer to only one breed.  The United Kennel Club in the US uses the English version of the name "Slovak Cuvac".

King Shepherd: The King Shepherd is a dog breed developed from crossing German Shepherd Dog with Shiloh Shepherd and long-coated European lines of German Shepherd along with the Great Pyrenees in the 1990s.

Pyrenean Shepherd: The Pyrenean Shepherd (known in France originally, and also in non-AKC registries such as the UKC, as the Berger des Pyrénées, and in Spain as the Pastor de los Pirineos) is a medium-small breed of dog native to the Pyrenees mountains in southern France and northern Spain, bred since at least medieval times for herding livestock, especially sheep.  It worked as an active herder together with the Great Pyrenees, another mountain dog, which acted as the flock's guardian.

Maremma Sheepdog: The Maremma Sheepdog, in Italian Cane da pastore Maremmano-Abruzzese, is a breed of livestock guardian dog indigenous to central Italy, particularly to Abruzzo and the Maremma region of Tuscany and Lazio.  It has been used for centuries by Italian shepherds to guard sheep from wolves.  The literal English translation of the name is "The dog of the shepherds of the Maremma and Abruzzese region".  The English name of the breed derives from that of the Maremma marshlands, where until recently shepherds, dogs and hundreds of thousands of sheep over-wintered, and where the breed is today abundant although sheep-farming has decreased substantially.  The breed is widely employed in Abruzzo, where sheep herding remains vital to the rural economy and the wolf remains an active and protected predator.  Similar breeds include the Pyrenean Mountain Dog, the Kuvasz of Hungary, the Tatra of Poland, the Cuvac of Slovakia and the Šarplaninac (although not white), with all of which it may share a common ancestor; and the Akbash Dog of Turkey.

Great Pyrenees: The Pyrenean Mountain Dog, known as the Great Pyrenees in North America, is a large breed of dog used as a livestock guardian dog.  It should not be confused with the Pyrenean Mastiff.
