Hip Dysplasia (canine)
In dogs, hip dysplasia is an abnormal formation of the hip socket that, in its more severe form, can eventually cause lameness and arthritis of the joints. It is a genetic (polygenic) trait that is affected by environmental factors. It is common in many dog breeds, particularly the larger breeds, and is the most common single cause of arthritis of the hips. During growth, both the ball (the head of the femur, or thighbone) and the socket in the pelvis (acetabulum) must grow at equal rates. In hip dysplasia, this uniform growth during puppyhood does not occur. The result is laxity (looseness) of the joint, followed by degenerative joint disease (DJD) or osteoarthritis (OA), which is the body's attempt to stabilize the loose hip joint. Overview Normal hip anatomy In the normal anatomy of the hip joint, the almost spherical end of the femur head (the caput, or caput ossis femoris) fits into the acetabulum (a concave socket located in the pelvis). The bony surfaces of the femur he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vertebral Column
The vertebral column, also known as the backbone or spine, is part of the axial skeleton. The vertebral column is the defining characteristic of a vertebrate in which the notochord (a flexible rod of uniform composition) found in all chordata, chordates has been replaced by a segmented series of bone: vertebrae separated by intervertebral discs. Individual vertebrae are named according to their region and position, and can be used as anatomical landmarks in order to guide procedures such as Lumbar puncture, lumbar punctures. The vertebral column houses the spinal canal, a cavity that encloses and protects the spinal cord. There are about 50,000 species of animals that have a vertebral column. The human vertebral column is one of the most-studied examples. Many different diseases in humans can affect the spine, with spina bifida and scoliosis being recognisable examples. The general structure of human vertebrae is fairly typical of that found in mammals, reptiles, and birds. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subluxation
A subluxation is an incomplete or partial dislocation of a joint or organ. According to the World Health Organization (WHO), a subluxation is a "significant structural displacement", and is therefore always visible on static imaging studies, such as X-rays. In contrast, the chiropractic belief of "vertebral subluxation" may or may not involve a significant displacement or even pain or clear dysfunction.WHO guidelines on basic training and safety in chiropractic p. 4, including footnote.

Spaniel
A spaniel is a type of gun dog. Spaniels were especially bred to flush game out of denser brush. By the late 17th century, spaniels had been specialized into water and land breeds. The extinct English Water Spaniel was used to retrieve water fowl shot down with arrows. Land spaniels were setting spaniels—those that crept forward and pointed their game, allowing hunters to ensnare them with nets, and springing spaniels—those that sprang pheasants and partridges for hunting with falcons, rabbits and smaller mammals such as rats and mice for hunting with greyhounds. During the 17th century, the role of the spaniel dramatically changed as Englishmen began hunting with flintlocks for wing shooting. Charles Goodall and Julia Gasow (1984) write that spaniels were "transformed from untrained, wild beaters, to smooth, polished gun dogs." The word "spaniel" would seem to be derived from the medieval French ''espaigneul''"Spanish"to modern French, ''espagnol''. Definition and descr ...

Mastiff
A mastiff is a large and powerful type of dog. Mastiffs are among the largest dogs, and typically have a short coat, a long low-set tail and large feet; the skull is large and bulky, the muzzle broad and short (brachycephalic) and the ears drooping and pendant-shaped. European and Asian records dating back 3,000 years show dogs of the mastiff type. Mastiffs have historically been guard dogs, protecting homes and property, although throughout history they have been used as hunting dogs, war dogs and for blood sports, such as fighting each other and other animals, including bulls, bears and even lions. Historical and archaeological evidence suggests that mastiffs have long been distinct in both form and function from the similarly large livestock guardian dogs from which they were most likely developed; they also form separate genetic populations. The Fédération Cynologique Internationale and some kennel clubs group the two types together as molossoid dogs; some modern livest ...

Rottweiler
The Rottweiler (, ) is a breed of domestic dog, regarded as medium-to-large or large. The dogs were known in German as , meaning Rottweil butchers' dogs, because their main use was to herd livestock and pull carts laden with butchered meat to market. This continued until the mid-19th century when railways replaced droving. Although still used to herd stock in many parts of the world, Rottweilers are now also used as search and rescue dogs, guard dogs, and police dogs.Adolf Pienkoss, ''The Rottweiler'', 3rd ed., Borken, Germany: Internationale Föderation der Rottweilerfreunde, 2008. History According to the FCI Standard, the Rottweiler is considered to be one of the oldest surviving dog breeds. Its origin goes back to Roman times. These dogs were kept as herder or driving dogs. They marched over the Alps with the Roman legions, protecting the humans and driving their cattle. In the region of Rottweil, these dogs met and mixed with the native dogs in a natural crossing. ...

Golden Retriever
The Golden Retriever is a Scottish breed of retriever dog of medium size. It is characterised by a gentle and affectionate nature and a striking golden coat. It is commonly kept as a pet and is among the most frequently registered breeds in several Western countries. It is a frequent competitor in dog shows and obedience trials; it is also used as a gundog, and may be trained for use as a guide dog. The breed was created by Sir Dudley Marjoribanks at his Scottish estate Guisachan in the late nineteenth century. He cross-bred Flat-coated Retrievers with Tweed Water Spaniels, with some further infusions of Red Setter, Labrador Retriever and Bloodhound. The breed was recognised by the Kennel Club in 1913, and during the interwar period spread to many parts of the world. History The Golden Retriever was developed in Scotland in the nineteenth century by Sir Dudley Marjoribanks (later to become Baron Tweedmouth) from Flat-coated Retrievers judiciously crossed with Twe ...

Nova Scotia Duck Tolling Retriever
The Nova Scotia Duck Tolling Retriever is a medium-sized gundog bred primarily for hunting. It is often referred to as a "toller". It is the smallest of the retrievers, and is often mistaken for a small Golden Retriever. Tollers are intelligent, eager to please, alert, and energetic. The name "toller" is derived from their ability to lure waterfowl within gunshot range. The breed originated in Yarmouth County, Nova Scotia, Canada. The American Kennel Club ranks the toller as the 87th most popular dog breed. History The breed was developed in the Acadian community of Little River Harbour in Yarmouth County, Nova Scotia, around the beginning of the 19th century. The toller was originally referred to as the Little River Duck Dog before being officially recognized by the Canadian Kennel Club in 1945 as a purebred dog. The toller is a mixture of retrievers, spaniels, setters, and possibly a farm collie mongrel, although this has yet to be confirmed. The breed was perfected in the ...

Retriever
A retriever is a type of gun dog that retrieves game for a hunter. Generally gun dogs are divided into three major classifications: retrievers, flushing spaniels, and pointing breeds. Retrievers were bred primarily to retrieve birds or other prey and return them to the hunter without damage; retrievers are distinguished in that nonslip retrieval is their primary function. As a result, retriever breeds are bred for soft mouths and a great willingness to please, learn, and obey. A soft mouth refers to the willingness of the dog to carry game in its mouth without biting into it. "Hard mouth" is a serious fault in a hunting dog and is very difficult to correct. A hard-mouthed dog renders game unpresentable or at worst inedible. The retriever's willingness to please, patient nature and trainability have made breeds such as the Labrador retriever and Golden retriever popular as a disability assistance dog. The outstanding reputation of the retriever has landed both the Labrador an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Shepherd Dog
The German Shepherd or Alsatian is a German breed of working dog of medium to large size. The breed was developed by Max von Stephanitz using various traditional German herding dogs from 1899. It was originally bred as a herding dog, for herding sheep. It has since been used in many other types of work, including disability assistance, search-and-rescue, police work, and warfare. It is commonly kept as a companion dog, and according to the Fédération Cynologique Internationale had the second-highest number of annual registrations in 2013. History During the 1890s, attempts were being made to standardise dog breeds. Dogs were being bred to preserve traits that assisted in their job of herding sheep and protecting their flocks from predators. In Germany this was practised within local communities, where shepherds selected and bred dogs. It was recognised that the breed had the necessary skills for herding sheep, such as intelligence, speed, strength and keen senses o ...
