Question: What do Samoyed and Pyrenean Shepherd have in common?

Context paragraphs:
Samoyedic languages: The Samoyedic ( ) or Samoyed languages ( ) are spoken on both sides of the Ural mountains, in northernmost Eurasia, by approximately 25,000 people altogether.  They derive from a common ancestral language called Proto-Samoyedic, and form a branch of the Uralic languages.  Having separated perhaps in the last centuries BC, they are not a diverse group of languages, and are traditionally considered to be an outgroup, branching off first from the other Uralic languages.

Pyrenean ibex: The Pyrenean ibex ("Capra pyrenaica pyrenaica"), Spanish common name bucardo, was one of the four subspecies of the Spanish ibex or Iberian wild goat, a species endemic to the Iberian Peninsula.  Pyrenean ibex were most common in the Cantabrian Mountains, Southern France, and the northern Pyrenees.  This species was common during the Holocene and Upper Pleistocene, during which their morphology, primarily some skulls, of the Pyrenean ibex was found to be larger than other "Capra" subspecies in southwestern Europe from the same time.

Perianal gland tumor: A perianal gland tumor is a type of tumor found near the anus in dogs that arises from specialized glandular tissue found in the perineum.  Perianal glands do not exist in cats.  It is also known as a hepatoid tumor because of the similarity in cell shape to hepatocytes (liver cells).  It is most commonly seen in intact (not neutered) dogs and is the third most common tumor type in intact male dogs.  There are two types of perianal gland tumors, perianal gland adenomas, which are benign, and perianal gland adenocarcinomas, which are malignant.  Both have receptors for testosterone.  Perianal gland adenomas are three times more likely to be found in intact male dogs than females, and perianal gland adenocarcinomas are ten times more common in male dogs than females.  The most commonly affected breeds for adenomas are the Siberian Husky, Cocker Spaniel, Pekingese, and Samoyed; for adenocarcinomas the most commonly affected breeds are the Siberian Husky, Bulldog, and Alaskan Malamute.

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.

Fritillaria pyrenaica: Fritillaria pyrenaica is a species of flowering plant in the family Liliaceae, native to the Pyrenees in Spain and France.  Common names include Pyrenean fritillary and Pyrenean snake's-head.  It is a bulbous perennial growing to 45 cm .  The pendent, bell-shaped flowers are borne in spring.  They have recurved tepals which are purple tinged with brown and yellow.  Like other species in this genus, notably "F. meleagris", they are strongly chequered.

Spanish Romanesque: Spanish Romanesque to designate the spatial division of the Romanesque art corresponding to Hispanic-Christian kingdoms of the Iberian Peninsula in the 11th and 12th centuries.  However, its stylistic features are essentially common to the European Romanesque, and in the particular differentiated between areas that usually subdivided.  The southern half of the peninsula lacks of Romanesque art since remained under Muslim rule (Andalusi art).  The Romanesque in the central area of the peninsula is low and late, with virtually no presence at south of the Ebro and the Tagus; It is the northern third peninsular the area where are concentrated the Romanesque buildings.  In view of the fact that the Romanesque is introduced into the peninsula from east to west, for the purposes of its study, the regional delimitation is done in the same direction: in "eastern kingdoms" (the kingdoms or Pyrenean areas: Catalan Romanesque, Aragonese Romanesque and Navarrese Romanesque), and "western kingdoms" (Castilian-Leonese Romanesque, Asturian Romanesque, Galician Romanesque and Portuguese Romanesque).

Samoyed (dog): The Samoyed ( or ; Russian: Самоедская собака or Самоед ) is a breed of large herding dog, from the spitz group, with a thick, white, double-layer coat.  It takes its name from the Samoyedic peoples of Siberia.  These nomadic reindeer herders bred the fluffy white dogs to help with the herding, and to pull sleds when they moved.  An alternate name for the breed, especially in Europe, is Bjelkier.

Quercus pyrenaica: Quercus pyrenaica, commonly known as Pyrenean oak, is a tree native to southwestern Europe and northwestern Africa.  Despite its common name, it is rarely found in the Pyrenees Mountains and is more abundant in central and southern Spain.

Horminum: Horminum is a genus of flowering plants in the family Lamiaceae, comprising a single species, Horminum pyrenaicum.  Common names include Dragonmouth and Pyrenean Dead-nettle.
