Snouts
A snout is the protruding portion of an animal's face, consisting of its nose, mouth, and jaw. In many animals, the structure is called a muzzle, rostrum, or proboscis. The wet furless surface around the nostrils of the nose of many mammals is called the rhinarium (colloquially this is the "cold wet snout" of some mammals). The rhinarium is often associated with a stronger sense of olfaction. Variation Snouts are found on many mammals in a variety of shapes. Some animals, including ursines and great cats, have box-like snouts, while others, like shrews, have pointed snouts. Pig snouts are flat and cylindrical. Primates Strepsirrhine primates have muzzles, as do baboons. Great apes have reduced muzzles, with the exception being human beings, whose face does not have protruding jaws nor a snout but merely a human nose. Dogs The muzzle begins at the stop, just below the eyes, and includes the dog's nose and mouth. In the domestic dog, most of the upper muzzle contains organs for ...

Dog Anatomy
Dog anatomy comprises the anatomical studies of the visible parts of the body of a domestic dog. Details of structures vary tremendously from breed to breed, more than in any other animal species, wild or domesticated, as dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier that stood only at the shoulder, in length along the head and body, and weighed only . The heaviest dog was an English Mastiff named Zorba which weighed . The tallest known adult dog is a Great Dane that stands at the shoulder. Anatomy Source: Muscles The following is a list of the muscles in the dog, along with their origin, insertion, action and innervation.

Domestic Dog
The dog (''Canis familiaris'' or ''Canis lupus familiaris'') is a domesticated descendant of the wolf. Also called the domestic dog, it is Domestication of the dog, derived from the extinct Pleistocene wolf, and the modern wolf is the dog's nearest living relative. Dogs were the first species to be domesticated by hunter-gatherers over 15,000 years ago before the development of agriculture. Due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a starch-rich diet that would be inadequate for other Canidae, canids. The dog has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. Dog breeds vary widely in shape, size, and color. They perform many roles for humans, such as Hunting dog, hunting, Herding dog, herding, Sled dog, pulling loads, Guard dog, protection, Police dog, assisting police and the Dogs in warfare, military, Pet, companionsh ...

Black And Tan Coonhound
The Black and Tan Coonhound is a breed of hunting dog. Developed in the United States from crosses between the Bloodhound and the Black and Tan Virginia Foxhound, this scent hound runs its game entirely by scent and is used primarily for raccoon hunting. Description According to the FCI breed standard Black and Tan Coonhound males should be in height with females slightly smaller at although it does not specify a weight range. The United Kennel Club does however include guideline weights of males with females ranging from . The height proportions quoted by the UKC differ from the FCI and allow males to be and females . The coat is short, dense and glossy. The eyes are hazel to brown, the ears are long, wide, and thin, are set low and far back on the dog's head, and hang well down the neck. The black and tan markings are similar to the Doberman's and the Rottweiler's. The Black and Tan Coonhound's bark is loud and baying; it has been described as a deep howl. The br ...

Brachycephalic
Brachycephaly (derived from the Ancient Greek '' βραχύς'', 'short' and '' κεφαλή'', 'head') is the shape of a skull shorter than typical for its species. It is perceived as a desirable trait in some domesticated dog and cat breeds, notably the pug and Persian, and can be normal or abnormal in other animal species. In humans, the cephalic disorder is known as flat head syndrome, and results from premature fusion of the coronal sutures, or from external deformation. The coronal suture is the fibrous joint that unites the frontal bone with the two parietal bones of the skull. The parietal bones form the top and sides of the skull. This feature can be seen in Down syndrome. In anthropology, human populations have been characterized as either dolichocephalic (long-headed), mesaticephalic (moderate-headed), or brachycephalic (short-headed). The usefulness of the cephalic index was questioned by Giuseppe Sergi, who argued that cranial morphology provided a better mean ...

English Cocker Spaniel
The English Cocker Spaniel is a breed of gun dog. It is noteworthy for producing one of the most varied numbers of pups in a litter among all dog breeds. The English Cocker Spaniel is an active, good-natured, sporting dog standing well up at the withers and compactly built. There are "field" or "working" cockers and "house" cockers. It is one of several varieties of spaniel and is the foundation of its American cousin, the American Cocker Spaniel. The English Cocker is closer to the working-dog form of the Field Spaniel and the English Springer Spaniel. Outside the US, the breed is usually known simply as the Cocker Spaniel, as is the American Cocker Spaniel within the US. The word ''cocker'' is commonly held to stem from their use to hunt woodcocks. The breed can have litters of anywhere from 3 to 12 puppies. History Spaniel type dogs have been found in art and literature for almost 500 years. Initially, spaniels in England were divided among land spaniels and water ...

Dolichocephalic
Dolichocephaly (derived from the Ancient Greek δολιχός 'long' and κεφαλή 'head') is a condition where the head is longer than would be expected, relative to its width. In humans, scaphocephaly is a form of dolichocephaly. Dolichocephalic dogs (such as German Shepherds) have elongated noses. This makes them vulnerable to fungal diseases of the nose such as aspergillosis. In humans the anterior–posterior diameter (length) of dolichocephaly head is more than the transverse diameter (width). It can be present in cases of Sensenbrenner syndrome, Crouzon syndrome, Sotos syndrome, CMFTD as well as Marfan syndrome. See also * Brachycephaly * Cephalic index * Plagiocephaly Plagiocephaly, also known as flat head syndrome, is a condition characterized by an asymmetrical distortion (flattening of one side) of the skull. A mild and widespread form is characterized by a flat spot on the back or one side of the head cause ... References External links Congenital d ...

Wolf
The wolf (''Canis lupus''; : wolves), also known as the gray wolf or grey wolf, is a large canine native to Eurasia and North America. More than thirty subspecies of ''Canis lupus'' have been recognized, and gray wolves, as popularly understood, comprise wild subspecies. The wolf is the largest extant member of the family Canidae. It is also distinguished from other ''Canis'' species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller ''Canis'' species, such as the coyote and the golden jackal, to produce fertile hybrids with them. The banded fur of a wolf is usually mottled white, brown, gray, and black, although subspecies in the arctic region may be nearly all white. Of all members of the genus ''Canis'', the wolf is most specialized for cooperative game hunting as demonstrated by its physical adaptations to tackling large prey, its more social nature, and its highly advanc ...

Spitz
Spitz (derived from the German word ''spitz'' 'pointed') is a type of domestic dog characterized by long, thick, and often white fur, and pointed ears and muzzles. The tail often curls over the dog's back or droops. While all of the breeds resemble primitive dogs, smaller breeds resemble foxes, while larger breeds resemble jackals, coyotes, wolves, and even dingoes. The exact origins of spitz dogs are not known, though most of the spitzes seen today originate from the Arctic region or Siberia. The type was described as ''Canis pomeranus'' by Johann Friedrich Gmelin in his revision of ''Systema Naturae'' in 1788. Characteristics Spitzes are well suited to living in harsh northern climates. They often have an insulating, waterproof undercoat that is denser than the topcoat to trap warmth. Small, upright ears help to reduce the risk of frostbite, square proportions and thick fur that grows on the paws protects the dogs from sharp ice. Many spitz breeds, like the Japanese Akita ...

Sled Dogs
A sled dog is a dog trained and used to pull a land vehicle in harness, most commonly a sled over snow. Sled dogs have been used in the Arctic for at least 8,000 years and, along with watercraft, were the only transportation in Arctic areas until the introduction of semi-trailer trucks, snowmobiles and airplanes in the 20th century, hauling supplies in areas that were inaccessible by other methods. They were used with varying success in the explorations of both poles, as well as during the Alaskan gold rush. Sled dog teams delivered mail to rural communities in Alaska, Yukon, Northwest Territories and Nunavut. Sled dogs today are still used by some rural communities, especially in areas of Russia, Canada, and Alaska as well as much of Greenland. They are used for recreational purposes and racing events, such as the Iditarod Trail and the Yukon Quest. History Sled dogs are used in countries such as Canada, Greenland, Siberia, Chukotka, Norway, Sweden, and Alaska. Sled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rough Collie
The Rough Collie (also known as the Long-Haired Collie) is a long-coated dog breed of medium to large size that, in its original form, was a type of collie used and bred for herding sheep in Scotland. More recent breeding has focused on the Collie as a show dog, and also companion. The breed specifications call for a distinctive long narrow tapered snout and tipped (''semiprick'') ears, so some dogs have their ears taped when young. Rough Collies generally come in shades of sable and white (sometimes mahogany), blue merle, tri-colored, and colour-headed white. Originating in the 19th century, the breed is now well known through the stories of author Albert Payson Terhune about his dog '' Lad'', and later with Eric Knight's character of '' Lassie'' and her novels, movies, and television shows. There is a smooth-coated variety known as a Smooth Collie; some breed organisations, including both the American and Canadian Kennel Clubs, consider smooth-coat and rough-coat collies t ...
