Entropion
Entropion is a medical condition in which the eyelid (usually the lower lid) folds inward. It is very uncomfortable, as the eyelashes continuously rub against the cornea causing irritation. Entropion is usually caused by genetic factors. This is different from when an extra fold of skin on the lower eyelid causes lashes to turn in towards the eye ( epiblepharon). In epiblepharons, the eyelid margin itself is in the correct position, but the extra fold of skin causes the lashes to be misdirected. Entropion can also create secondary pain of the eye (leading to self trauma, scarring of the eyelid, or nerve damage). The upper or lower eyelid can be involved, and one or both eyes may be affected. When entropion occurs in both eyes, this is known as "bilateral entropion". Repeated cases of trachoma infection may cause scarring of the inner eyelid, which may cause entropion. In human cases, this condition is most common to people over 60 years of age. Symptoms Symptoms of entropion incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Welsh Springer Spaniel
The Welsh Springer Spaniel (''Welsh'': ''Llamgi Cymru'') is a dog breed, breed of dog and a member of the spaniel family. Thought to be comparable to the old Land Spaniel, they are similar to the English Springer Spaniel and historically have been referred to as both the Welsh Spaniel and the Welsh Cocker Spaniel. They were relatively unknown until a succession of victories in dog trials by the breed increased its popularity. Following recognition by The Kennel Club in 1902, the breed gained the modern name of Welsh Springer Spaniel. The breed's coat only comes in a single colour combination of white with red markings, usually in a piebald pattern. Loyal and affectionate, they can become very attached to family members and are wary of strangers. Health conditions are limited to those common among many breeds of dog, although they are affected more than average by Hip dysplasia (canine), hip dysplasia and some eye conditions. They are a working dog, bred for hunting, and while n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chow Chow
The Chow Chow is a spitz-type of dog breed originally from northern China. The Chow Chow is a sturdily built dog, square in profile, with a broad skull and small, triangular, erect ears with rounded tips. The breed is known for a very dense double coat that is either smooth or rough. The fur is particularly thick in the neck area, giving it a distinctive ruff or mane appearance. The coat may be shaded/self-red, black, blue, cinnamon/fawn, or cream. History The Chow Chow has been identified as a basal breed that predates the emergence of the modern breeds in the 19th Century. One writer proposed that the Chow Chow originated in China 2,000 years ago or possibly originated in Arctic Asia 3,000 years ago which migrated to Mongolia, then to China. One Chinese legend mentions large war dogs from Central Asia that resembled black-tongued lions. One Chinese ruler was said to own 5,000 Chows. The Chinese also used Chows to pull dog sleds through swampy terrain, and this was r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trachoma
Trachoma is an infectious disease caused by bacterium ''Chlamydia trachomatis''. The infection causes a roughening of the inner surface of the eyelids. This roughening can lead to pain in the eyes, breakdown of the outer surface or cornea of the eyes, and eventual blindness. Untreated, repeated trachoma infections can result in a form of permanent blindness when the eyelids turn inward. The bacteria that cause the disease can be spread by both direct and indirect contact with an affected person's eyes or nose. Indirect contact includes through clothing or flies that have come into contact with an affected person's eyes or nose. Children spread the disease more often than adults. Poor sanitation, crowded living conditions, and not enough clean water and toilets also increase spread. Efforts to prevent the disease include improving access to clean water and treatment with antibiotics to decrease the number of people infected with the bacterium. This may include treating, all ...

Cavalier King Charles Spaniel
The Cavalier King Charles Spaniel is a British breed of toy dog of spaniel type. Four colours are recognised: Blenheim (chestnut and white), tricolour (black/white/tan), black and tan, and ruby; the coat is smooth and silky. The lifespan is usually between eight and twelve years. The Cavalier King Charles changed dramatically in the late seventeenth century, when it was inter-bred with flat-nosed breeds. Until the 1920s, it shared the same history as the smaller King Charles Spaniel. Breeders attempted to recreate what they considered to be the original configuration – a dog resembling Charles II's spaniel of the English Civil War period, when supporters of the king were known as Cavaliers. History During the early part of the 18th century, John Churchill, 1st Duke of Marlborough, kept red and white King Charles type spaniels for hunting. The duke recorded that they were able to keep up with a trotting horse. His estate was named Blenheim in honour of his victory at t ...

Human Eye
The human eye is a sensory organ, part of the sensory nervous system, that reacts to visible light and allows humans to use visual information for various purposes including seeing things, keeping balance, and maintaining circadian rhythm. The eye can be considered as a living optical device. It is approximately spherical in shape, with its outer layers, such as the outermost, white part of the eye (the sclera) and one of its inner layers (the pigmented choroid) keeping the eye essentially light tight except on the eye's optic axis. In order, along the optic axis, the optical components consist of a first lens (the cornea—the clear part of the eye) that accomplishes most of the focussing of light from the outside world; then an aperture (the pupil) in a diaphragm (the iris—the coloured part of the eye) that controls the amount of light entering the interior of the eye; then another lens (the crystalline lens) that accomplishes the remaining focussing of light into ...

Shar Pei
The Shar Pei (Cantonese: ''shā pèih'' or Mandarin: 沙皮 ''shā pí'') is a dog breed from southern China. Traditionally kept as a property guardian, the Shar Pei was driven to the brink of extinction in the 20th century. The breed is known in the West for its deep wrinkles, whilst a traditional less wrinkled form is maintained in Hong Kong. History There are no records indicating the origins of the Shar Pei, although it closely resembles effigies of an un-wrinkled type of guard dog kept in southern China during the Han dynasty; some believe the modern breed, along with the Chow Chow, descends from these dogs. The breed has been identified as a basal breed that predates the emergence of the modern breeds in the 19th century. The Shar Pei was once very popular, but war and political turmoil in China in the 20th century took its toll on the breed and by the 1970s it was close to extinction. In 1973 a Hong Kong businessman named Matgo Law appealed to the international commu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichiasis
Trichiasis ( , ) is a medical term for abnormally positioned eyelashes that grow back toward the eye, touching the cornea or conjunctiva. This can be caused by infection, inflammation, autoimmune conditions, congenital defects, eyelid agenesis and trauma such as burns or eyelid injury. Standard treatment involves removal or destruction of the affected eyelashes with electrology, specialized laser, or surgery. In many cases, removal of the affected eyelashes with forceps resolves the symptoms, although the problem often recurs in a few weeks when the eyelashes regrow. Severe cases may cause scarring of the cornea and lead to vision loss if untreated. Mild cases may not require treatment. Repeated cases of trachoma infection may cause trichiasis. Posterior misdirection of normal lashes most frequently affects the lower lid. In dogs Trichiasis in dogs is hair from the eyelid growing in the wrong direction and rubbing on the eye, causing irritation. It usually occurs at the late ...

Neapolitan Mastiff
The Neapolitan Mastiff or is an Italian breed of large dog of mastiff type. It descends from the traditional guard dogs of central Italy. It was recognised as a breed by the Ente Nazionale della Cinofilia Italiana in 1949, and accepted by the Fédération Cynologique Internationale in 1956. It is closely related to the Cane Corso. History The Neapolitan Mastiff derives from the traditional catch and guard dogs of central Italy. Selection of the breed was begun in 1947 by Piero Scanziani, who had seen one at an exhibition in Naples in 1946. He drew up the first standard, which in 1949 was officially recognised by the Ente Nazionale della Cinofilia Italiana. It received full acceptance from the Fédération Cynologique Internationale in 1956.

English Springer Spaniel
The English Springer is a dog breed, breed of gun dog in the Spaniel group traditionally used for flushing and retrieving game. It is an affectionate, excitable breed with a typical lifespan of twelve to fourteen years. They are very similar to the Welsh Springer Spaniel and are descended from the Norfolk Spaniel, Norfolk or Shropshire Spaniels of the mid-19th century; the breed has diverged into separate show and working lines. The breed suffers from average health complaints. The show-bred version of the breed has been linked to "rage syndrome", although the disorder is very rare. It is closely related to the Welsh Springer Spaniel and very closely to the English Cocker Spaniel; less than a century ago, springers and cockers would come from the same litter. The smaller "cockers" hunted woodcock while the larger littermates were used to flush, or "spring", game. In 1902, The Kennel Club recognized the English Springer Spaniel as a distinct breed. They are used as sniffer dogs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boxer (dog)
The Boxer is a medium to large, short-haired dog breed of mastiff-type, developed in Germany. The coat is smooth and tight-fitting; colors are fawn, brindled, or white, with or without white markings. Boxers are brachycephalic (they have broad, short skulls), have a square muzzle, mandibular prognathism (an underbite), very strong jaws, and a powerful bite ideal for hanging on to large prey. The Boxer was bred from the Old English Bulldog and the now extinct Bullenbeisser, which became extinct by crossbreeding rather than by a decadence of the breed. The Boxer is a member of both The Kennel Club and American Kennel Club (AKC) Working Group.http://www.akc.org/dog-breeds/boxer/#standard "Get to Know the Boxer", 'The American Kennel Club', Retrieved 14 May 2014 The first Boxer club was founded in 1895, with Boxers being first exhibited in a dog show for St. Bernards in Munich the next year.

Cocker Spaniel
Cocker Spaniels are dogs belonging to two breeds of the spaniel dog type: the American Cocker Spaniel and the English Cocker Spaniel of which are commonly called simply Cocker Spaniel in their countries of origin. In the early 20th century, Cocker Spaniels also included small hunting spaniels. Cocker Spaniels were originally bred as hunting dogs in the UK, with the term "cocker" deriving from their use to hunt the Eurasian woodcock. When the breed was brought to the United States, it was bred to a different Breed standard (dogs), standard, which enabled it to specialize in hunting the American woodcock. Further physical changes were bred into the cocker in the United States during the early part of the 20th century. Spaniels were first mentioned in the 14th century by Gaston III, Count of Foix in his work the ''Livre de Chasse''. The "cocking" or "cocker spaniel" was a type of field or land spaniel in the 19th century. Prior to 1901, Cocker Spaniels were only separated from Field ...
