Pekingese Dog
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 A companion dog is a dog which is not primarily a working dog but a pet. The primary function of a companion dog is not to perform a useful job but to provide companionship to humans. A companion dog can also be called an emotional support anima ..., and its name refers to the city of Beijing (Peking) 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 dog, 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 Cephalic index#Brachycephalic ...

Melanistic Mask
A melanistic mask (also referred to as a mask or masking) is a dog coat pattern that gives the appearance of a mask on the dog's face. The hairs on the muzzle, and sometimes entire face or ears, are colored by eumelanin instead of pheomelanin pigment. Eumelanin is typically black, but may instead be brown, dark gray, or light gray-brown. Pheomelanin ranges in color from pale cream to mahogany. The trait is caused by M264V (''EM''), a completely dominant allele (form) of the melanocortin 1 receptor gene. Appearance At minimum, a melanistic mask will appear on the muzzle, and may also be visible on the eartips, entire ears, or entire face. Hairs in those areas will be colored by eumelanin instead of pheomelanin pigment, making it look as though the dog has a mask on its face. Eumelanin is usually black, but may instead be liver (also known as chocolate; dark brown), blue (also known as slate; dark grey), or isabella (also known as lilac; light grey-brown); accordingly, a mask m ...

Hot Spot (veterinary Medicine)
Pyotraumatic dermatitis, also known as a hot spot or acute moist dermatitis, is a common infection of the skin surface of dogs, particularly those with thick or long coats. It occurs following self-inflicted trauma of the skin. Pyotraumatic dermatitis rarely affects cats. Signs The dog persistently licks, chews, scratches or rubs at a focal area of skin, which quickly causes hair loss. The skin becomes red, moist and weeps. The affected area is obviously defined and separate from the surrounding healthy skin and coat. Usually only one area of the skin is affected. The size of the affected area is variable. If the area is difficult for the dog to scratch, or if the disease is caught early, hair may still be present. Areas commonly affected include the rump above the tail, the head and neck near the ears, and the top and sides of the lumbar area. Cause Pyotraumatic dermatitis is caused by self-inflicted trauma to the skin, which is incited by pain or irritation, such as infestation ...

Pedigree Dogs Exposed
''Pedigree Dogs Exposed'' is a BBC One investigative documentary, produced by Jemima Harrison, which looks into health and welfare issues facing pedigree dogs in the United Kingdom. It was originally broadcast on 19 August 2008. The Kennel Club (KC), the governing body of pedigree dogs in the UK which runs the prestigious Conformation show, dog breed show Crufts, was criticised for allowing breed standards, judging standards, and breeding practices to compromise the health of pedigree dogs. The programme generated much criticism of the Kennel club, Kennel Club. It also caused various sponsors and trade exhibitors to withdraw their participation from Crufts and other Kennel Club events. The BBC—which had broadcast Crufts for 42 years—withdrew its coverage of Crufts in 2009, and chose not to renew it thereafter. The Kennel Club initially denied the filmmakers' assertion that many of the dogs suffered from diseases and stated that the vast majority of dog breeds are healthy. I ...

Progressive Retinal Atrophy
Progressive retinal atrophy (PRA) is a group of genetic diseases seen in certain breeds of dogs and, more rarely, cats. Similar to retinitis pigmentosa in humans, it is characterized by the bilateral degeneration of the retina, causing progressive vision loss culminating in blindness. The condition in nearly all breeds is inherited as an autosomal recessive trait, with the exception of the Siberian Husky (inherited as an X chromosome linked trait) and the Bullmastiff (inherited as an autosomal dominant trait). There is no treatment. Types of PRA In general, PRAs are characterised by initial loss of rod photoreceptor cell function followed by that of the cones and for this reason night blindness is the first significant clinical sign for most dogs affected with PRA. As other retinal disorders, PRA can be divided into either dysplastic disease, where the cells develop abnormally, and degenerative, where the cells develop normally but then degenerate during the dog's lifetime. ...

Keratoconjunctivitis Sicca
Dry eye syndrome, also known as keratoconjunctivitis sicca, is the condition of having dry eyes. Symptoms include dryness in the eye, irritation, redness, discharge, blurred vision, and easily fatigued eyes. Symptoms range from mild and occasional to severe and continuous. Dry eye syndrome can lead to blurred vision, instability of the tear film, increased risk of damage to the ocular surface such as scarring of the cornea, and changes in the eye including the neurosensory system. Dry eye occurs when either the eye does not produce enough tears or when the tears evaporate too quickly. This can be caused by age, contact lens use, meibomian gland dysfunction, pregnancy, Sjögren syndrome, vitamin A deficiency, omega-3 fatty acid deficiency, LASIK surgery, and certain medications such as antihistamines, some blood pressure medication, hormone replacement therapy, and antidepressants. Chronic conjunctivitis such as from tobacco smoke exposure or infection may also lead to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corneal Ulcers In Animals
A corneal ulcer, or ulcerative keratitis, is an inflammatory condition of the cornea involving loss of its outer layer. It is very common in dogs and is sometimes seen in cats. In veterinary medicine, the term ''corneal ulcer'' is a generic name for any condition involving the loss of the outer layer of the cornea, and as such is used to describe conditions with both inflammatory and traumatic causes. Corneal anatomy of the dog and cat The cornea is a transparent structure that is part of the outer layer of the eye. It refracts light and protects the contents of the eye. The cornea is about one-half to one millimeter thick in the dog and cat. The trigeminal nerve supplies the cornea via the long ciliary nerves. There are pain receptors in the outer layers and pressure receptors deeper. Transparency is achieved through a lack of blood vessels, pigmentation, and keratin, and through the organization of the collagen fibers. The collagen fibers cross the full diameter of the corn ...

Brachycephalic Airway Obstructive Syndrome
Brachycephalic obstructive airway syndrome (BOAS), also known as brachycephalic airway obstructive syndrome (BAOS), brachycephalic airway syndrome (BAS), and brachycephalic syndrome (BS), is a pathological condition affecting brachycephalic, short nosed dogs and cats which can lead to severe respiratory distress. There are four different anatomical abnormalities that contribute to the disease, all of which occur more commonly in brachycephalic breeds: an elongated soft palate, stenotic nares, a hypoplastic trachea, and everted laryngeal saccules (a condition which occurs secondary to the other abnormalities). Because all of these components make it more difficult to breathe in situations of exercise, stress, or heat, an animal with these abnormalities may be unable to take deep or fast enough breaths to blow off carbon dioxide. This leads to distress and further increases respiratory rate and heart rate, creating a vicious cycle that can quickly lead to a life-threatening situatio ...

Major Trauma
Major trauma is any injury that has the potential to cause prolonged disability or death. There are many causes of major trauma, blunt and penetrating, including falls, motor vehicle collisions, stabbing wounds, and gunshot wounds. Depending on the severity of injury, quickness of management, and transportation to an appropriate medical facility (called a trauma center) may be necessary to prevent loss of life or limb. The initial assessment is critical, and involves a physical evaluation and also may include the use of imaging tools to determine the types of injuries accurately and to formulate a course of treatment. In 2002, unintentional and intentional injuries were the fifth and seventh leading causes of deaths worldwide, accounting for 6.23% and 2.84% of all deaths. For research purposes the definition often is based on an Injury Severity Score (ISS) of greater than 15. Classification Injuries generally are classified by either severity, the location of damage, or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mongrel
A mongrel, mutt, or mixed-breed dog is a dog that does not belong to one officially recognized breed, including those that result from intentional breeding. Although the term ''mixed-breed dog'' is sometimes preferred, many mongrels have no known purebred ancestors. Crossbreed dogs, and " designer dogs", while also a mix of breeds, differ from mongrels in being intentionally bred. At other times, the word ''mongrel'' has been applied to informally purpose-bred dogs such as curs, which were created at least in part from mongrels, especially if the breed is not officially recognized. Although mongrels are viewed as of less commercial value than intentionally bred dogs, they are thought to be less susceptible to genetic health problems associated with inbreeding (based on the theory of heterosis), and have enthusiasts and defenders who prefer them to intentionally bred dogs. Estimates place the prevalence of mongrels at 150 million animals worldwide. Terminology Mixed-breed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Withers
Withers are the ridge between the shoulder blades of an animal, typically a quadruped. In many species, this ridge is the tallest point of the body. In horses and dogs, it is the standard place to measure the animal's height. In contrast, cattle are often measured to the top of the hips. The term (pronounced ) derives from Old English ''wither'' ("against'), because the withers are the part of a Working_animal#Draft_animals , draft animal that pushes against a Mechanical load, load. Horses The withers in horses are formed by the dorsal spinal processes of roughly the 3rd through 11th thoracic vertebrae, which are unusually long in this area. Most horses have 18 thoracic vertebrae. The processes at the withers can be more than long. Since they do not move relative to the ground as the horse's head does, the withers are used as the measuring point for the height of a horse. Horses are sometimes measured in hand (unit), hands – one hand is . Horse heights are extremely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
