Dingo

The dingo (Canis lupus dingo) is a free-ranging dog found mainly in Australia, as well as Southeast Asia, where it is said to have originated. It is currently classified as a subspecies of the grey wolf, Canis lupus. A dingo's habitat ranges from deserts to grasslands and the edges of forests. Dingoes will normally make their dens in deserted rabbit holes and hollow logs close to an essential supply of water.

The dingo is the largest terrestrial predator in Australia, and plays an important role as an apex predator. However, the dingo is seen as a pest by sheep farmers due to frequent attacks on livestock. Conversely, their predation on rabbits, kangaroos and rats is of benefit to cattle stations. For many Australians, the dingo is a cultural icon. There is fear of the species becoming extinct, similar to the case of the thylacine in Tasmania, commonly known as the Tasmanian tiger, thought to have become extinct in the 20th century.

The dingo is seen by many as being responsible for thylacine extinction on the Australian mainland about two thousand years ago, although a recent study challenges this view. Dingoes have a prominent role in the culture of Aboriginal Australians as a feature of stories and ceremonies, and they are depicted on rock carvings and cave paintings. The dingo has several names in both scientific and non-scientific literature, with "dingo" being the most commonly used.

The dingo is regarded as part of the native Australian fauna by many environmentalists and biologists, as these dogs existed on the continent before the arrival of the Europeans and a mutual adaption of the dingoes and their surrounding ecosystems had occurred. However, the contrary view has dingoes as just another introduced predator that are only native to Thailand.

In Australia, the term "wild dog" is also widely used, but generally includes dingoes as well as dingo-hybrids and other feral dogs. Domestic and pariah dogs in southern Asia share so many characteristics with Australian dingoes that they are now considered to be members of the same taxon Canis lupus dingo, a particular subspecies of Canis lupus. While the relationship with humans varies widely among these animals, they are all quite similar in terms of physical features.

African wild dog

Lycaon pictus is a canid found only in Africa, especially in savannas and lightly wooded areas. It is variously called the African wild dog, African hunting dog, Cape hunting dog, painted dog, painted wolf, painted hunting dog, spotted dog, or ornate wolf. The scientific name "Lycaon pictus" is derived from the Greek for "wolf" and the Latin for "painted".

African wild dog Credit

It is the only canid species to lack dewclaws on the forelimbs. This is the largest African canid and is the world's second largest extant wild canid, behind only the gray wolf,. Adults typically weigh 18-36 kilograms (40–79 lb). A tall, lean animal, it stands about 75 cm (30 in) at the shoulder, with a head and body length of 75–141 cm (30–56 in) plus a tail of 30 to 45 cm (12 to 18 in).

African wild dog Credit

Animals in southern Africa are generally larger than those in eastern or western Africa. Little sexual dimorphism is shown, though judging by skeletal dimensions, males are usually 3-7% larger. It has a dental formula of 3.1.4.23.1.4.3 for a total of 42 teeth. The premolars are relatively large compared with those of other canids, allowing it to consume a large quantity of bone, much like the hyena.

African wild dog (Lycaon pictus)

The heel of the lower carnassial M1 is crested with a single cusp, which enhances the shearing capacity of teeth and thus the speed at which prey can be consumed. This feature is called trenchant heel and is shared with two other canids: the Asian dhole and the South American bush dog.

African wild dog Credit

The African wild dog lives and hunts in large packs. Like most members of the dog family, it is a cursorial hunter, meaning it pursues its prey in a long, open chase. These chases may occur at great speeds of up to 66 km/hr for 10 to 60 minutes, and over great distances (at about 50km/hr for 5.6km).  Lycaon pictus is the only extant species in the genus Lycaon.

American Pit Bull Terrier

The American Pit Bull Terrier (APBT) is a medium-sized, solidly built, short haired dog whose early ancestors came from England and Ireland. It is a member of the molosser breed group. The American Staffordshire Terrier and The American Pit Bull Terrier (APBT) by breed are from the same lineage; Staffordshires was the name given by AKC, and American Pit Bull Terriers by UKC.

The real difference between the two breeds is 6-8" in height and 25-35 lb in weight; the American Staffordshire being the larger of the two. The dog was bred first to bait bulls and bears. When bear-baiting and bull-baiting were deemed inhumane, rat-baiting and dog fighting became more popular. The APBT Breed was used in both sports, and its prevalence in being put in pits with rats, or other dogs led to "pit" being added to its name.

 

The American Pit Bull is medium-sized, and has a short coat and smooth well-defined muscle structure. Its eyes are round to almond shaped, and its ears are small to medium in length and can be natural or cropped. The tail is slightly thick and tapers to a point. The coat is glossy, smooth, short, and stiff to the touch. The accepted coat color can vary widely, but, both the AKC and UKC do not recognize merle coloring.

Twelve countries in Europe, as well as Australia, Canada, Ecuador, Malaysia, New Zealand, Puerto Rico, Singapore, and Venezuela have enacted some form of breed-specific legislation on pit bull-type dogs, including American Pit Bull Terriers, ranging from outright bans to restrictions and conditions on ownership. The state of New South Wales in Australia places restrictions on the breed, including mandatory sterilization.

A few counties, and cities in the United States as well as the Province of Ontario in Canada, have outright banned ownership of the American Pit Bull terrier, and the breed is banned in the UK. Old Family Red Nose (OFRN) is an old strain of American Pit Bull Terriers known for their specific reddish colorization. A dog of the red-nosed strain has a copper-red nose and coat, red lips, red toe nails, and red or amber eyes.

Chihuahua

The Chihuahua is the smallest breed of dog and is named for the state of Chihuahua in Mexico. Chihuahuas come in a wide variety of sizes, head shapes, colors, and coat lengths. The Chihuahua’s history is puzzling and there are many theories surrounding the origin of the breed. Both folklore and archeological finds show that the breed originated in Mexico.

The most common and most likely theory is that Chihuahuas are descended from the Techichi, a companion dog favored by the Toltec civilization in Mexico. No records of the Techichi are available prior to the 9th century, although dog pots from Colima, Mexico, buried as part of the western Mexico shaft tomb tradition which date back to 300 BC are thought to depict Techichis.

It is probable that earlier ancestors were present prior to the Mayans as dogs approximating the Chihuahua are found in materials from the Great Pyramid of Cholula, predating 1530 and in the ruins of Chichen Itza on the Yucatán Peninsula. Chihuahuas are very small dogs, and are the smallest breed recognized by some kennel clubs. There are two main varieties recognized by kennel clubs, the short-haired and the long-haired.

There is a second varietal split as well, having to do with the shape and size of the dog's head. These two descriptive classifications are "apple head" and "deer head", but only the apple head is conformationally correct. Breed standards for this dog do not generally specify a height; only a weight and a description of their overall proportions.

The temperament of its human guardian can make a difference in the temperament of the pup. Tempered Chihuahuas can be easily provoked to attack, and are therefore generally unsuitable for homes with small children. The breed tends to be fiercely loyal to one particular guardian and in some cases may become over protective of the person, especially around other people or animals.

Doberman Pinscher

The Doberman Pinscher (alternatively spelled Dobermann in many countries) or simply Doberman, is a breed of domestic dog originally developed around 1890 by Karl Friedrich Louis Dobermann, a tax collector from Germany. Doberman Pinschers are among the most common of pet breeds, and the breed is well known as an intelligent, alert, and loyal companion dog. Although once commonly used as guard dogs or police dogs, this is less common today.

In many countries, Doberman Pinschers are often one of the most recognizable breeds, in part because of their actual roles in society, and in part because of media attention. Recent careful breeding has greatly improved the disposition of this breed, and the modern Doberman Pinscher is an energetic and lively breed suitable for companionship and family life. Although many Dobermans have been outdoor dogs, they are best suited to live indoors.

Kennel club standards describe Doberman Pinschers as dogs of medium-large size with a square build and short coat. They are compactly built and athletic with endurance and swiftness. The Doberman Pinscher should have a proud, watchful, determined, and obedient temperament. The dog was originally intended as a guard dog, so males should have a masculine, muscular, noble appearance. Females are thinner, but should not be spindly.

The Doberman is a dog of medium size. Although the breed standards vary among kennel and breed clubs, the dog typically stands between 26 to 28 inches, 27.5 being ideal (66 to 72 cm), the female is typically somewhere between 24 to 26 inches, 25.5 being ideal (61 to 68 cm). The Doberman has a square frame: its length should equal its height to the withers, and the length of its head, neck and legs should be in proportion to its body.

European lines, particularly those from the former Yugoslavia and former Soviet Union, tend to be larger than those in North America. There are no standards for the weight of the Doberman Pinscher. The ideal dog must have sufficient size for an optimal combination of strength, endurance and agility. The male generally weighs between 75-90.4 lbs. (34 and 45 kg) and the female between 59.5-79.4 pounds (27 and 41 kg).

Siberian Husky

The Siberian Husky (Russian: сибирский хаски, "Sibirsky husky") is a medium to large, dense-coat working dog breed that originated in north-eastern Siberia. The breed belongs to the Spitz genetic family. It is recognizable by its thickly furred double coat, sickle tail, erect triangular ears, and distinctive markings. Huskies are an active, energetic, and resilient breed whose ancestors came from the extremely cold and harsh environment of the Siberian Arctic.

Siberian Huskies were bred by the Chukchi of Northeastern Asia to pull heavy loads long distances through difficult conditions. The dogs were imported into Alaska during the Nome Gold Rush and later spread into the United States and Canada. They were initially sent to Alaska and Canada as sled dogs but rapidly acquired the status of family pets and show dogs.

Because of their efficiency as a working breed, most huskies are bred to be able to withstand long work days on little amounts of food. The Siberian Husky's coat is thicker than most other dog breeds, comprising two layers: a dense undercoat and a longer topcoat of short, straight guard hairs. It protects the dogs effectively against harsh Arctic winters, but the coat also reflects heat in the summer.

The American Kennel Club describes the Siberian Husky's eyes as "an almond shape, moderately spaced and set slightly obliquely." The eyes of a Siberian Husky are ice-blue, dark blue, amber, or brown. Show-quality dogs are preferred to have neither pointed nor square noses. Siberian Husky tails are heavily furred; these dogs will often curl up with their tails over faces and noses in order to provide additional warmth.

The tail should be expressive, held low when the dog is relaxed, and curved upward in a "sickle" shape when excited or interested in something. The breed standard indicates that the males of the breed are ideally between 21 and 23.5 inches (53 and 60 cm) tall at the withers and weighing between 45 and 60 pounds (20 and 27 kg). Females are smaller, growing to between 20 to 22 inches (51 to 56 cm) tall at the withers and weighing between 35 to 50 pounds (16 to 23 kg).

German Shepherd

The German Shepherd is a breed of large-sized dog that originated in Germany. German Shepherds are a relatively new breed of dog, with their origin dating to 1899. As part of the Herding Group, German Shepherds are working dogs developed originally for herding sheep. Since that time, however, because of their strength, intelligence, trainability and obedience.

German Shepherds around the world are often the preferred breed for many types of work, including search-and-rescue, police and military roles and even acting. German Shepherds are the second-most popular dog in the United States  and fourth-most popular in the United Kingdom. When the UK Kennel first accepted registrations for the breed in 1919, fifty-four dogs were registered and by 1926 this number had grown to over 8,000.

The breed first gained international recognition at the decline of World War I after returning soldiers spoke highly of the breed and animal actors Rin Tin Tin and Strongheart popularised the breed further. The first German Shepherd Dog registered in the United States was Queen of Switzerland; however, her offspring suffered from defects as the result of poor breeding, which caused the breed to suffer a decline in popularity during the late 1920s.

 The breed was named Deutscher Schäferhund by von Stephanitz, literally translating to "German Shepherd Dog". The breed was so named due to its original purpose of assisting shepherds in herding and protecting sheep. At the time, all other herding dogs in Germany were referred to by this name; they thus became known as Altdeutsche Schäferhunde or Old German Shepherd Dogs.

The modern German Shepherd breed is criticized by some for straying away from von Stephanitz's original ideology for the breed: that German Shepherds should be bred primarily as working dogs and that breeding should be strictly controlled to eliminate defects quickly. He believed that, above all else, German Shepherds should be bred for intelligence and working ability.

Great Dane

The Great Dane, also denoted as Grand Danois, is a German breed of domestic dog (Canis lupus familiaris) known for its giant size. The name of the breed in Germany is Deutsche Dogge (German Mastiff). They are known for their enormous bodies and great height. The Great Dane is one of the world's tallest dog breeds; the current world record holder, measuring 112 cm (44 in) from paw to shoulder, is "Zeus".

Their large size belies their friendly nature, with Great Danes known for seeking physical affection with their owners. The Great Dane combines, in its regal appearance, dignity, strength and elegance with great size and a powerful, well-formed, smoothly muscled body. It is one of the giant working breeds, but is unique in that its general conformation must be so well balanced that it never appears clumsy, and shall move with a long reach and powerful drive.

The Great Dane is a short haired breed with a strong galloping figure. In the ratio between length and height, the Great Dane should be square. The male dog should not be less than 30 in (76 cm) at the shoulders, a female 28 in (71 cm). Danes under minimum height are disqualified. From year to year, the tallest living dog is typically a Great Dane.

Like most dogs, Great Danes require daily walks to maintain their health. However, it is important not to over exercise this breed, particularly when young. Great Dane puppies grow very large, very fast, which puts them at risk of joint and bone problems. Because of a puppy's natural energy, Dane owners often take steps to minimize activity while the dog is still growing.

Given their large size, Great Danes continue to grow (mostly gaining weight) longer than most dogs. Even at one year of age a Great Dane will continue to grow for several more months. Great Danes, like most giant dogs, have a fairly slow metabolism. This results in less energy and less food consumption per pound of dog than in small breeds. The average life span of Great Danes is 6 to 8 years. Like many larger breeds, Great Danes are at particular risk for hip dysplasia.

American Bulldog

The American Bulldog is a breed of sporting and working dogs. The names associated with the Bully and Standard types are those of the breeders who were influential in developing them, John D. Johnson (Bully) and Alan Scott (Standard). The American bulldog is a stocky, well built, strong-looking dog, with a large head and a muscular build. Its coat is short and generally smooth.

 

The breed is a light to moderate shedder; however, they should be brushed on regular basis. Colors, while historically predominantly white with patches of red, black, or brindle, have grown in recent years to include many color patterns including black, red, brown, fawn, and all shades of brindle. The color conformation is quite varied, but solid black or any degree of merle is considered a cosmetic fault, and a blue color is a disqualification by the NKC Breed Standard. Black pigmentation on the nose and eye rims is preferred, with only some pink allowed.

 

Eye color is usually brown, but heterochromia also occurs, although considered a cosmetic fault. American Bulldogs can be droolers; this varies and is more prevalent in the Bully type, which is generally a larger, heavier dog with a shorter muzzle. Standard or Performance types are generally more athletic with longer muzzles and a more square head. It is important to note that many modern American Bulldogs are a combination of the two types usually termed "hybrid."

 

In general, American Bulldogs weigh between 27 to 54 kg (60 to 120 lb) and are 52 to 70 cm (20 to 28 in) at the withers, but have been known to greatly exceed these dimensions, especially in the "out of standard," nonworking stock. American Bulldogs are typically confident, social, and active dogs that are at ease with their families. It is not uncommon for an American Bulldog to require a high level of attention due to their highly emotional personality. They bond strongly with their owners.

They are capable of jumping in excess of seven feet vertical due to the dense muscle build of the breed. Young American Bulldogs may be slightly aloof with strangers, but as they mature the breed's normal confidence should assert itself. This breed tolerates children and can do very well with them, provided they are socialized early and understand their limits. The more exposure to good training practices, other dogs, and people, the more likely the success at being controlled both inside and outside of their environment.

Dogue de Bordeaux

The Dogue de Bordeaux, Bordeaux Mastiff, French Mastiff or Bordeauxdog is a French Mastiff breed and one of the most ancient French dog breeds..They are a typical brachycephalic molossoid type breed. Bordeaux are very powerful dogs, with a very muscular body. This brawny breed has been put to work in many different capacities, from pulling carts and hauling heavy objects, to guarding flocks and, historically, the castles of the European elite.

 

The Dogue de Bordeaux is a well balanced, muscular and massive dog with a powerful build. The Dogue's size should come mostly from width and muscles, rather than height. The breed is set somewhat low to the ground and is not tall like the English Mastiff. The body of the Dogue de Bordeaux is thick-set, straight top-line and a gentle rounded croup.

 

The front legs should be straight and heavy-boned, well up on pasterns, down to tight cat like feet. The straight tail begins thickly at the base and then tapers to a point at the end. It should not reach lower than the hocks. The tail is thick at the base and tapers to the tip and is set and carried low. The breed is to be presented in a completely natural condition with intact ears, tail, and natural dewclaws.

 

It should be evaluated equally for correctness in conformation, temperament, movement, and overall structural soundness. The breed standards by European FCI and the American Kennel Club specify a minimum weight of 100 pounds (45 kg) for a female and 115 pounds (52 kg) for a male. There is no formally stated maximum weight, but dogs must be balanced with regard to their overall type and the conformation standards of the breed.

The standard states that the desirable height, at maturity, should range between 23 1⁄2 to 27 inches (60 to 69 cm) for male dogs and from 22 1⁄2 to 25 1⁄2 inches (57 to 65 cm) for females. Deviation from these margins is considered a fault. The Dogue has a mean litter size of 8.1 puppies (range 2-17. The breed has a high stillborn and early neonatal mortality rate.

English Mastiff

The English Mastiff, referred to by most Kennel Clubs simply as the Mastiff, is a breed of large dog perhaps descended from the ancient Alaunt and Pugnaces Britanniae. Distinguishable by enormous size, massive head, and a limited range of colours, but always displaying a black mask, the Mastiff is noted for its gentle temperament. The lineage of modern dogs can be traced back to the early 19th century, and the modern type was stabilised in the 1880s.

 

 

 

Following a period of sharp decline, the Mastiff has increased its worldwide popularity. With a massive body, broad skull and head of generally square appearance, it is the largest dog breed in terms of mass. Though the Irish Wolfhound and Great Dane are taller, they are not nearly as robust. The body is large with great depth and breadth, especially between the forelegs, causing these to be set wide apart.

 

 

 

The colours of the Mastiff coat are differently described by various kennel clubs, but are essentially fawn or apricot, or those colours as a base for black brindle. A black mask should occur in all cases. The fawn is generally a light "silver" shade, but may range up to a golden yellow. The apricot may be a slightly reddish hue up to a deep, rich red. The brindle markings should ideally be heavy, even and clear stripes, but may actually be light, uneven, patchy, faint or muddled. Pied Mastiffs occur rarely.

 

 

 

Other non-standard colours include black, blue brindle, and chocolate (brown) mask. Some Mastiffs have a heavy shading caused by dark hairs throughout the coat or primarily on the back and shoulders. This is not generally considered a fault. Brindle is dominant over solid colour. Apricot is dominant over fawn, though that dominance may be incomplete. Most of the colour faults are recessive, though black is so rare in the Mastiff that it cannot be certain if it is recessive, or a mutation that is dominant.

The greatest weight ever recorded for a dog, 343 pounds (156 kg), was that of an English Mastiff from England named Aicama Zorba of La Susa, although claims of larger dogs exist. According to the 1989 edition of the Guinness Book of Records, in March 1989, when he was 7 years old, Zorba stood 35 inches (89 cm) at the shoulder and was 8.25 feet (251 cm) from the tip of his nose to the tip of his tail, about the size of a small donkey.

Rottweiler

The Rottweiler is a medium to large size breed of domestic dog. The dogs were known as "Rottweil butchers' dogs" (German: Rottweiler Metzgerhund) because they were used to herd livestock and pull carts laden with butchered meat and other products to market. The Rottweiler was employed in its traditional roles until the mid-19th century when railways replaced droving for herding livestock to market.

 

While still used in herding, Rottweilers are now also used as search and rescue dogs, as guide dogs for the blind, as guard dogs or police dogs, and in other roles. Although a versatile breed used in recent times for many purposes, the Rottweiler is one of the oldest of herding breeds. A multi-faceted herding and stock protection dog, it is capable of working all kinds of livestock under a variety of conditions.

The various German Rottweiler Clubs amalgamated to form the Allgemeiner Deutscher Rottweiler Klub (ADRK, General German Rottweiler Club) in 1921. This was officially recorded in the register of clubs and associations at the district court of Stuttgart on 27 January 1924. The ADRK is recognised worldwide as the home club of the Rottweiler.

The coat consists of an outer coat and an undercoat. The outer coat is of medium length, coarse, dense and flat. The undercoat should be present on the neck and thighs. The undercoat must not show through the outer coat. Rottweilers living in hot climates may have acclimatised and may be missing the undercoat. Rottweiler coats tend to be low maintenance, although they experience heavy shedding before their seasons (females) or seasonally (males). 

The color and markings of a Rottweiler are very distinctive. A Rottweiler is always, by any breed club standards, black with well-defined mahogany or rust-colored markings that do not take up more than ten percent of the dog's body color. All Rottweilers standard to AKC specifications have one mahogany dot above each eye on the inner brow ridge, on the cheeks, one strip on each side of the snout; cheek markings do not cross over the bridge of the nose, the top of the nose should remain black.

Cane Corso

The Cane Corso is an Italian breed of dog, for years valued highly in Italy as a companion, guardian and hunter. The Cane Corso is a large Italian Molosser, which is closely related to the Neapolitan Mastiff. In name and form the Cane Corso predates its cousin the Neapolitan Mastiff. It is well muscled and less bulky than most other Mastiff breeds.

 

The breed is known as a true and quite possibly the last of the coursing Mastiffs. The official Fédération Cynologique Internationale (FCI) standard expects ideal dogs to stand 62–72 cm (24–28 in) at the withers, with females in the lower range and males in the higher. Weight should be in keeping with the size and stature of these dogs, ranging from 45 to 50 kg (99 to 110 lb).

 

The overall impression should be of power, balanced with athleticism. A Corso should be moderately tight skinned; however, some dewlap on the neck is normal, and the bottom of the jawline should be defined by the hanging lip. The head of the Cane Corso is arguably its most important feature. It is large and imposing. In general, it gives the appearance of regality.

 

The forehead should be flat and convergent to the muzzle. The muzzle is flat, rectangular (when viewed from above), and generally as wide as it is long approximately 33% the total length of the skull (a ratio of 2:1). The eyes are almond in shape, set straight and when viewed from the front, set slightly above the line of the muzzle. Darker eyes are preferred, however, the color of the eyes tends to emulate the shade of brindling in the coat.

Traditionally the ears are cropped in equilateral triangles that stand erect. Cani Corso appear in two basic coat colours: black and fawn. This is further modified by genetic pigment dilution to create grey (from black) and frumentino or formentino(from fawn) colours. Brindling of varying intensity is common on both basic coat colours as well, creating tigrato (black brindle), and Grigio Tigrato (grey brindle).
