Karl Friedrich Louis Dobermann
Karl Friedrich Louis Dobermann (; ; 2 January 1834 – 9 June 1894) was the first breeder of Doberman Pinscher. He started the creation of this dog breed in the town of Apolda, in the Grand Duchy of Saxe-Weimar-Eisenach around 1890, following the Franco-Prussian War. Ed. TFH Publications Inc, 2009. . P. 7 Dobermann served in the dangerous role of local , and ran the Apolda dog pound. With access to dogs of many breeds, he aimed to create a breed that would be ideal for protecting him during his collections, which took him through many dangerous, bandit-infested areas. He set out to breed a new type of dog that, in his opinion, would be the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cropping (animal)
Cropping is the removal of part or all of the external flaps of an animal's ear. The procedure sometimes involves bracing and taping the remainder of the ears to train them to point upright. Almost exclusively performed on dogs, it is an old practice that was once done for perceived health, practical or cosmetic reasons. Veterinary science states there is no medical or physical advantage to the animal from the procedure,Slatter, Douglas H. (2002''Textbook of small animal surgery''3rd edition. Philadelphia: W.B. Saunders (imprint of Elsevier Health Sciences), 2896 pages, , p.1746 leading to concerns of animal cruelty over performing unnecessary surgery on animals. In modern times, cropping is banned in many nations, but is still legal in a limited number of countries. Where permitted, it is seen only in certain breeds of dog, such as the pit bull, Doberman Pinscher, Schnauzer, Great Dane, Boxer and Cane Corso. History and purposes In 2000, veterinarian Bruce Fogle wrote: Tradi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guard Dog
A guard dog or watchdog (not to be confused with an attack dog) is a dog used to watch for and guard property against unwanted or unexpected human or animal intruders. The dog is discerning so that it does not annoy or attack the resident humans of the house. History The use of dogs as guardians is well known since ancient times. The Romans used to put mosaics (''Cave canem'' mosaics) at the entrance of the houses to warn visitors and intruders of the presence of dangerous dogs at the property. One of the first dog types used as guardians were the ancestral Mastiff-type landraces of the group known as Livestock guardian dogs which protected livestock against large predators such as wolves, bears and leopards. Orthrus is a famous example of a livestock guardian dog from the Greek mythology known for guarding Geryon's red cattle. Some ancient guard dogs in more urban areas, such as the extinct bandogges, were chained during the day and released at night to protect propertie ...

Canine Follicular Dysplasia
Follicular dysplasia is a genetic disease of dogs causing alopecia, also called hair loss. It is caused by hair follicles that are misfunctioning due to structural abnormality. There are several types, some affecting only certain breeds. Diagnosis is achieved through a biopsy, and treatment is rarely successful. Certain breeds, such as the Mexican Hairless Dog and Chinese Crested Dog, are bred specifically for alopecia. Structural follicular dysplasia Structural follicular dysplasia varies by breed but all involve weakened hairs that break easily. Hair loss is originally seen in areas of repeated grooming or trauma, for instance the neck because of contact with a collar. Hair regrowth may occur, but the hair will be even weaker and the pattern will repeat. The dogs are affected between the ages of two to four years, and it is most commonly seen on the back towards the tail. Progression of the hair loss to cover the trunk can occur. Commonly affected breeds *Irish Water Spaniel *Po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verband Für Das Deutsche Hundewesen
Verband für das Deutsche Hundewesen (VDH) is Germany's Kennel club for dogs and represents Germany in the world federation Fédération Cynologique Internationale. It is headquartered in Dortmund, Germany. As the country-wide controlling body, the VDH represents 167 member organizations with more than 650,000 members. In addition, there are over 250 different breeds of dog in the VDH. History On July 16, 1906, the :de:Kartell der Stammbuchführender Spezialklubs für Jagd- und Nutzhunde was founded as the second German umbrella organization alongside the delegate commission; first president was :de:Albert de Gingins. In 1914, the cartel changed its name to "Kartell der Rassezuchtvereine und allgemeine Verbände" and in 1925 to "Deutsches Kartell für Hundewesen" (DKH). After Hitler's seizure of power in 1933, the Reichsverband für die Deutsche Hundewesen (RDH) was established as a "unitary organization" and the German Cartel for Dogs, Delegates Commission and Association ...

Albinism
Albinism is the congenital absence of melanin in an animal or plant resulting in white hair, feathers, scales and skin and pink or blue eyes. Individuals with the condition are referred to as albino. Varied use and interpretation of the terms mean that written reports of albinistic animals can be difficult to verify. Albinism can reduce the survivability of an animal; for example, it has been suggested that albino alligators have an average survival span of only 24 hours due to the lack of protection from UV radiation and their lack of camouflage to avoid predators. It is a common misconception that all albino animals have characteristic pink or red eyes (resulting from the lack of pigment in the iris allowing the blood vessels of the retina to be visible), however this is not the case for some forms of albinism. Familiar albino animals include in-bred strains of laboratory animals (rats, mice and rabbits), but populations of naturally occurring albino animals exist in the wil ...

Tyrosinase
Tyrosinase is an oxidase that is the rate-limiting enzyme for controlling the production of melanin. The enzyme is mainly involved in two distinct reactions of melanin synthesis otherwise known as the Raper Mason pathway. Firstly, the hydroxylation of a monophenol and secondly, the conversion of an o-diphenol to the corresponding o-quinone. o-Quinone undergoes several reactions to eventually form melanin. Tyrosinase is a copper-containing enzyme present in plant and animal tissues that catalyzes the production of melanin and other pigments from tyrosine by oxidation. It is found inside melanosomes which are synthesized in the skin melanocytes. In humans, the tyrosinase enzyme is encoded by the ''TYR'' gene. Catalyzed reaction Tyrosinase carries out the oxidation of phenols such as tyrosine and dopamine using dioxygen (O2). In the presence of catechol, benzoquinone is formed (see reaction below). Hydrogens removed from catechol combine with oxygen to form water. The substrate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melanin
Melanin (; from el, μέλας, melas, black, dark) is a broad term for a group of natural pigments found in most organisms. Eumelanin is produced through a multistage chemical process known as melanogenesis, where the oxidation of the amino acid tyrosine is followed by polymerization. The melanin pigments are produced in a specialized group of cells known as melanocytes. Functionally, eumelanin serves as protection against Ultraviolet, UV radiation. There are five basic types of melanin: eumelanin, pheomelanin, neuromelanin, allomelanin and pyomelanin. The most common type is eumelanin, of which there are two types— brown eumelanin and black eumelanin. Pheomelanin, which is produced when melanocytes are malfunctioning due to derivation of the gene to its recessive format is a cysteine-derivative that contains polybenzothiazine portions that are largely responsible for the of red yellow tint given to some skin or hair colors. Neuromelanin is found in the brain. Research ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100.

Vertebra
The spinal column, a defining synapomorphy shared by nearly all vertebrates,Hagfish are believed to have secondarily lost their spinal column is a moderately flexible series of vertebrae (singular vertebra), each constituting a characteristic irregular bone whose complex structure is composed primarily of bone, and secondarily of hyaline cartilage. They show variation in the proportion contributed by these two tissue types; such variations correlate on one hand with the cerebral/caudal rank (i.e., location within the backbone), and on the other with phylogenetic differences among the vertebrate taxa. The basic configuration of a vertebra varies, but the bone is its ''body'', with the central part of the body constituting the ''centrum''. The upper (closer to) and lower (further from), respectively, the cranium and its central nervous system surfaces of the vertebra body support attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
