Medial Patellar Luxation
A luxating patella, sometimes called a trick knee, is a condition in which the patella, or kneecap, dislocates or moves out of its normal location. Patellar luxation is a common condition in dogs, particularly small and miniature breeds. The condition usually becomes evident between the ages of 4 and 6 months. It can occur in cats, as well, especially domestic short-haired cats. It also occurs in humans, where it can be associated with damage to the anterior cruciate ligament. There have been several reports of patella luxation in other species such as miniature pigs, alpacas, llamas, cattle and goats. Causes Rarely, it can be caused by some form of blunt trauma, but most frequently, it is a developmental, congenital defect. In congenital cases, it is frequently bilateral. The condition can also be inherited through genetics. This can also be caused by obesity. Diagnosis Diagnosis is made through palpation of the knee, to see whether it slips inside the joint more than would n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orthopedics
Orthopedic surgery or orthopedics ( alternatively spelt orthopaedics), is the branch of surgery concerned with conditions involving the musculoskeletal system. Orthopedic surgeons use both surgical and nonsurgical means to treat musculoskeletal trauma, spine diseases, sports injuries, degenerative diseases, infections, tumors, and congenital disorders. Etymology Nicholas Andry coined the word in French as ', derived from the Ancient Greek words ὀρθός ''orthos'' ("correct", "straight") and παιδίον ''paidion'' ("child"), and published ''Orthopedie'' (translated as ''Orthopædia: Or the Art of Correcting and Preventing Deformities in Children'') in 1741. The word was assimilated into English as ''orthopædics''; the ligature ''æ'' was common in that era for ''ae'' in Greek- and Latin-based words. As the name implies, the discipline was initially developed with attention to children, but the correction of spinal and bone deformities in all stages of life eventually ...

Maltese (dog)
Maltese dog refers both to an ancient variety of dwarf canine from Italy and generally associated also with the island of Malta, and to a modern breed of dog in the toy group. The contemporarvarietyis genetically related to the Bichon, Bolognese, and Havanese breeds. The precise link, if any, between the modern and ancient species is not known. Nicholas Cutillo suggested that Maltese dogs might descend from spitz-type canines, and that the ancient variety probably was similar to the latter Pomeranian breeds with their short snout, pricked ears, and bulbous heads. These two varieties, according to Stanley Coren, were perhaps the first dogs employed as human companions. The modern variety traditionally has a silky, pure-white coat, hanging ears and a tail that curves over its back, and weighs up to . The Maltese does not shed. The Maltese is kept for companionship, ornament, or competitive exhibition. Maltese dogs in antiquity The old variety of Maltese appears to have bee ...

Cat Diseases
The cat (''Felis catus'') is a domestic species of small carnivorous mammal. It is the only domesticated species in the family Felidae and is commonly referred to as the domestic cat or house cat to distinguish it from the wild members of the family. Cats are commonly kept as house pets but can also be farm cats or feral cats; the feral cat ranges freely and avoids human contact. Domestic cats are valued by humans for companionship and their ability to kill rodents. About 60 cat breeds are recognized by various cat registries. The cat is similar in anatomy to the other felid species: they have a strong flexible body, quick reflexes, sharp teeth, and retractable claws adapted to killing small prey. Their night vision and sense of smell are well developed. Cat communication includes vocalizations like meowing, purring, trilling, hissing, growling, and grunting as well as cat-specific body language. Although the cat is a social species, they are a solitary hunter. As a pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abyssinian (cat)
The Abyssinian is a breed of domestic short-haired cat with a distinctive "ticked" tabby coat, in which individual hairs are banded with different colors. They are also known simply as Abys. The source of the name is not because Ethiopia, formerly Abyssinia, is thought to be the original home of these cats, but because the first "Abyssinians" exhibited in shows in England were reported to have been imported to England from there. Its true origin — according to genetic studies — is likely to have been the coast of the Indian Ocean in parts of Southeast Asia, and its introduction to Abyssinia (and others) was through colonialists and merchants stopping through Calcutta. Although regarded as comparatively obscure in the past as a breed compared to others, the Abyssinian ranked in 2016 among the top five most popular breeds by The Cat Fancier Association and The International Cat Association. The breed's distinctive appearance, seeming long, lean and finely colored compared to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devon Rex
The Devon Rex is a tall-eared, short-haired breed of cat that emerged in England during the late 1950s. They are known for their slender bodies, wavy coat, and large ears. This breed of cat is capable of learning difficult tricks but can be hard to motivate. Breed history The Devon Rex is a breed of cat with a curly, very soft short coat similar to that of the Cornish Rex. They are often thought of as one of the most hypoallergenic cats available because of their type of coat. However, they are technically not hypoallergenic. The first Devon was discovered by Beryl Cox in Buckfastleigh, Devon, UK, in 1959. The breed was initially thought to be linked with the Cornish Rex; however, test mating proved otherwise. Appearance Hair Cats have three types of hair: guard hair, awn hair, and down hair. The Devon Rex's coat is unusual because there is little guard hair. The curl in Devon Rex fur is caused by a different mutation and gene than that of the Cornish Rex and German Rex, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teddy Roosevelt Terrier
The Teddy Roosevelt Terrier is a small to medium-sized American hunting terrier. It is lower-set, with shorter legs, and is more muscular with heavier bone density than the related American Rat Terrier. Much diversity exists in the history of the Teddy Roosevelt Terrier breed, and it shares a common early history with the American Rat Terrier, Fox Paulistinha, and Tenterfield Terrier. The Rat Terrier's background is said to stem from the terriers or other dogs that were brought over by early English and other working-class immigrants. Since the breed was a farm, hunting, and utility dog, little to no planned breeding was used other than breeding dogs with agreeable traits to each other to produce the desired work ethic in the dog. The Feist (dog), Bull Terrier, Smooth Fox Terrier, Manchester Terrier, Whippet, Italian Greyhound, the now extinct English White Terrier, Turnspit Dog, and Wry-legged Terrier all share in the Teddy Roosevelt Terrier's ancestry. These early ratting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plummer Terrier
The Plummer Terrier is a working terrier. It was originally bred by Brian Plummer to hunt vermin, especially rats. The breed, while unrecognized by any kennel club, is known for its rugged determination and hardiness. Origins and history In the late 1960s and throughout the 1970s, Brian Plummer worked as a somewhat reluctant teacher of several schools throughout southern Yorkshire and the Midlands. He was already well-known in his local neighborhood for going around with a pack of terriers to catch rats, when he decided to create his own terrier breed in the 1970s. Well-versed in breeding, he strove to produce a unique strain of terrier by mixing the Jack Russell Terrier with the Beagle, Fell Terrier, and Bull Terrier. These terriers were worked hard and as the breed developed, so too did Plummer's reputation as a breeder of hardy terriers that bred true to type. Initially known as the Huddlesford Rat Pack, the breed is now named after him. The Beagle introduced to Plumm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boston Terrier
The Boston Terrier is a breed of dog originating in the United States of America. This "American Gentleman" was accepted in 1893 by the American Kennel Club as a non-sporting breed. Color and markings are important when distinguishing this breed from the AKC standard. They should be either black, brindle or seal with white markings. Boston Terriers are small and compact with a short tail and erect ears. The AKC says they are highly intelligent and very easily trained. They are friendly and can be stubborn at times. The average life span of a Boston Terrier is around 11 to 13 years. The American Kennel Club ranked the Boston Terrier as the 21st most popular breed in 2019. History The Boston terrier breed originated around 1875, when Robert C. Hooper of Boston purchased from Edward Burnett a dog named Judge (known later as Hooper's Judge), which was of a bull and terrier type lineage. Hooper's Judge is directly related to the original bull and terrier breeds of the 19th and earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papillon (dog)
The Papillon (, French for 'butterfly eared), also called the Continental Toy Spaniel, is a breed of dog, of the spaniel type. One of the oldest of the toy spaniels, it derives its name from its characteristic butterfly-like look of the long and fringed hair on the ears. A Papillon with dropped ears is called a Phalene. Appearance and behavior Papillons are very intelligent and self-assured dogs that have a very easy time learning new tricks. These dogs can be sociable with children and strangers, but are generally reserved around new people. They can also be socialized to get along well with other pets, but care should be taken with rambunctious pets or cats with claws, as they may injure them. If not properly socialized, Papillons can be distrustful and exhibit aggressive tendencies toward other dogs and people. Papillons may also be very playful and affectionate. Widely known as great companion dogs, they have the spirit and energy to keep up with active families, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Chihuahua (dog)
The Chihuahua or es, Chihuahueño, italic=no is a Mexican breed of toy dog. It is named for the Mexican state of Chihuahua and is among the smallest of all dog breeds. It is usually kept as a companion animal or for showing. History DNA studies suggest that native American dogs entered North America from Siberia roughly 10,000 years ago, and were then isolated for some 9000 years until the arrival of the first Europeans; these pre-contact dogs exhibited a unique genetic signature that is now almost gone. A study based on sequencing of ancient dog genomes, published in 2020, suggests that this pre-colonial ancestry survives in two Mexican breeds, to the extent of about 4% in the Chihuahua (and some 3% in the Xoloitzcuintli). Colonial records refer to small, nearly hairless dogs at the beginning of the nineteenth century; one claims that sixteenth-century conquistadores found them plentiful in the region later known as Chihuahua. In a letter written in 1520, Hernan Cor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pekingese
The Pekingese (also spelled Pekinese) is a breed of toy dog, originating in China. The breed was favored by royalty of the Chinese Imperial court as a companion dog, and its name refers to the city of Peking (Beijing) where the Forbidden City is located. The breed has several characteristics and health issues related to its unique appearance. Because of its desirable characteristics, the Pekingese has been part of the development of designer crossbreeds, such as the Peekapoo (crossed with a poodle) and Peke-a-tese (crossed with a Maltese). Appearance Modern breeders and dog show judges seem to prefer the long-haired type over the more traditional spaniel-type coat. The Pekingese's flat face and large eyes are some of the breed's most obvious characteristics. The body is compact and low to the ground. Pekingese also have a muscular and durable body. The breed's unusual rolling gait may have been deliberately developed through selective breeding, to prevent the court dogs f ...
