Duck Toller
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 retriever, spaniel, setter, and possibly a farm collie mongrel, although the latter has yet to be confirmed. The breed was perfected in the ...

Pastern
The pastern is a part of the leg of a horse between the fetlock and the top of the hoof. It incorporates the Equine_forelimb_anatomy#Metacarpal_bones, long pastern bone (proximal phalanx) and the Equine_forelimb_anatomy#Middle_phalanx, short pastern bone (middle phalanx), which are held together by two sets of paired ligaments to form the pastern joint (proximal interphalangeal joint). Anatomically homologous to the two largest bones found in the human finger, the pastern was famously mis-defined by Samuel Johnson in A Dictionary of the English Language, his dictionary as "the knee of a horse". When a lady asked Johnson how this had happened, he gave the much-quoted reply: "Ignorance, madam, pure ignorance." Anatomy and importance The pastern consists of two bones, the uppermost called the "large pastern bone" or proximal phalanx, which begins just under the fetlock joint, and the lower called the "small pastern bone" or middle phalanx, located between the large pastern bone an ...

Addison's Disease
Addison's disease, also known as primary adrenal insufficiency, is a rare long-term endocrine disorder characterized by inadequate production of the steroid hormones cortisol and aldosterone by the two outer layers of the cells of the adrenal glands ( adrenal cortex), causing adrenal insufficiency. Symptoms generally develop slowly and insidiously and may include abdominal pain and gastrointestinal abnormalities, weakness, and weight loss. Darkening of the skin in certain areas may also occur. Under certain circumstances, an adrenal crisis may occur with low blood pressure, vomiting, lower back pain, and loss of consciousness. Mood changes may also occur. Rapid onset of symptoms indicates acute adrenal failure, which is a clinical emergency. An adrenal crisis can be triggered by stress, such as from an injury, surgery, or infection. Addison's disease arises when the adrenal gland does not produce sufficient amounts of the steroid hormones cortisol and (sometimes) a ...

Autoimmune Thyroiditis
In immunology, autoimmunity is the system of immune responses of an organism against its own healthy cells, tissues and other normal body constituents. Any disease resulting from this type of immune response is termed an "autoimmune disease". Prominent examples include celiac disease, diabetes mellitus type 1, Henoch–Schönlein purpura, systemic lupus erythematosus, Sjögren syndrome, eosinophilic granulomatosis with polyangiitis, Hashimoto's thyroiditis, Graves' disease, idiopathic thrombocytopenic purpura, Addison's disease, rheumatoid arthritis, ankylosing spondylitis, polymyositis, dermatomyositis, and multiple sclerosis. Autoimmune diseases are very often treated with steroids. Autoimmunity means presence of antibodies or T cells that react with self-protein and is present in all individuals, even in normal health state. It causes autoimmune diseases if self-reactivity can lead to tissue damage. History In the later 19th century, it was believed that the immune system ...

Collie Eye Anomaly
Collie eye anomaly (CEA) is a congenital, inherited, bilateral eye disease of dogs, which affects the retina, choroid, and sclera. It can be a mild disease or cause blindness. CEA is caused by a simple autosomal recessive gene defect. There is no treatment. Affected breeds It is known to occur in Collies ( smooth and rough collies), Shetland Sheepdogs, Australian Shepherds, Border Collies, Lancashire Heelers, Nova Scotia Duck Tolling Retrievers, and the Hokkaido. Frequency is high in Collies and Shetland Sheepdogs, and low in Border Collies and NSDTRs. In the United States, incidence in the genotype of collies has been estimated to be as high as 95 percent, with a phenotypic incidence of 80 to 85 percent. Pathogenesis CEA is caused by improper development of the eye. Failure of the cells of the posterior portion of the optic vesicles to express growth hormone affects the differentiation of other cells of the eye. The choroid, especially lateral to the optic disc, is hypopl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. ...

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. 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 head and of the acetabulum are covered by cartilage. While bones provide the strength necessary to support body weight, cartilage ensures a smooth fit and a wide range of motion. Normal hip function can be affected by congenital conditions such as dysplasia, trauma, and by acquired diseases such as osteoarthritis and rheumatoid arthritis. Dysplastic hip anatomy The hip could have ... [...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] |

Howl (sound)
Howling is a vocal form of animal communication seen in most canines, particularly wolves, coyotes, foxes, and dogs, as well as cats and some species of monkeys. Howls are lengthy sustained sounds, loud and audible over long distances, often with some variation in pitch over the length of the sound. Howling is generally used by animals that engage in this behavior to signal their positions to one another, to call the pack to assemble, or to note their territory. The behavior is occasionally copied by humans, and has been noted to have varying degrees of significance in human culture. In canines The long-distance howling of wolves and coyotes is one way in which canines communicate. Long-distance contact calls are common in Canidae, typically in the form of either barks (termed "pulse trains") or howls (termed "long acoustic streams"). Wolves howl to assemble the pack usually before and after hunts, to pass on an alarm particularly at a den site, to locate each other during a ...

Search And Rescue Dog
A search-and-rescue (SAR) dog is a dog trained to respond to crime scenes, accidents, missing persons events, as well as Natural disaster, natural or Disaster, man-made disasters. These dogs detect human scent, which is a distinct odor of skin flakes and water and oil secretions unique to each person and have been known to find people under water, snow, and collapsed buildings, as well as remains buried underground. SAR dogs are a non-invasive aid in the location of humans, alive or deceased.
