Abyssinian

The Abyssinian cat is said to be descended from a cat called Zula, brought to England by Captain Barrett Leonard when he returned from service in the Abyssinian wars in the 1860�s. Apparently he brought two cats, but Zula was the sole survivor. There is no verifiable record of Abyssinian cats directly descended from Zula, but Abyssinians were certainly exhibited at Crystal Palace in 1871, so that this breed may claim to be one of the original pedigree cats. Certainly every Abyssinian in the world is descended from cats bred in the Unitied Kingdom.

Physical Characters: The Abyssinian's body is of medium length, lithe, with well-developed muscles. The legs are slender in proportion to the body, with a fine bone structure. The paws are small and oval. The Abyssinian has a fairly long tail, broad at the base and tapering to a point.

The head is broad and moderately wedge-shaped, with almond-shaped eyes that can be gold, green, hazel or copper. The nose and chin usually form a straight vertical line when viewed in profile. Their alert, relatively large ears are broad and cupped at the base, and moderately pointed at the tips, where tuffs of hair commonly seen. Large ear tuffs are viewed as a must for show breeds. An M-shaped marking is sometimes found in the fur on the forehead.

Temperament: Abyssinians are extroverted, willful and intelligent, but are usually not "lap cats", being too preoccupied with exploring and playing as they would in their natural habitat. Although very popular among breeders and owners, Abyssinians aren't often used as show cats because of their shyness towards strangers and their timid nature. They have quiet, engaging voices that can often be misleading. Abys, as they are affectionately referred to by their fans, need a great deal of contact with the family to keep them happy and can get depressed without daily activity and attention. They generally get on well with other cats, although they need their space and the females can sometimes be irritable around other cats. Abyssinians are known for their curiosity and enjoy exploring their surroundings, including heights, although they are sensible cats that do not take unnecessary risks.

Inherited Defects of the Abyssinian Cat: The Abyssinian can be prone to patellar luxation (dislocation or slipping kneecap), renal amyloidosis (kidney disease), retinal atrophy (a rare eye condition that leads to impaired vision).
Abyssinian Cat Club - UK

The Abyssinian Cat Club (link to their website) in the UK was founded in 1929. Their first "members show" took place in an upper room in Brooke Street, Holborn, London, on March 12th 1930 as reported by the Times newspaper.At the time there were only about 30 Abyssinian cats in England. 21 of them were at the show. The Abyssinian was a rare breed in 1930. It is much less rare today, being almost common (but no less fine a cat).The Times newpaper described the breed as rather small and elegant with quite large ears. The journalist referred to the color of this cat breed as looking like that of a rabbit. One of the Abyssinians was melanistic black and the ticking was referred to as being caused by the tips of the individual hairs being blackish or dark brown. Perhaps of more interest the character was described as being rather shy and gentle and not liking strangers that much but very affectionate (presumably to those people and other animals that he/she was familiar with). {source: Times Archive - dated March 13th 1930}


Things of Interest
In 1963 an Abyssinian cat was worth about £700 ($1400 approx.). In today's money that is about £7000+ or $14,000 at least. This is perhaps a reflection of the rarity of the breed at that time. By my reckoning the breed is one of the least rare purebred cats today (see rare cat breeds). {src: Times Archive}

In the demanding world of the show cat, and if you want an Abyssinian that is truly of show cat quality, it is useful to take note of what are considered "faults" in appearance. These are purely cosmetic, of course.

Apparently in the 1970s breeders were less rigorous or the standard was a little easier to meet and some cats had a white patch on the neck/chest area (called a "locket" after lockets worn as jewelry). This is now considered a fault and has been largely bred out. White patches are caused by the white spotting gene or piebald gene, which is behind the tuxedo appearance of the well known non-pedigreed black and white cats (Tuxedo cats).
As mentioned above this cat's popularity is based in part on the beautifully ticked coat caused by the Agouti gene. The coat is also dependent on the presence of the tabby gene, which produces the familiar tabby pattern such as the lines (mackerel) pattern or in the Bengal cat the marbled pattern.
Such patterns are definitely a no go area for the Abyssinian cat as the coat needs to have a pure shaded (used in a laypersons sense) appearance. Patterns are considered a fault. These markings can be apparent as bands (rings) on the tail and legs and breeders use their knowledge of selective breeding to try and eliminate them.

In some cats a straight line in profile from the forehead to the end of the nose if considered the objective (I am thinking of the Modern Siamese). This is considered part of the "Oriental" look. The Abyssinian cat profile should have a nose "break". This means the profile where the top of the nose meets the forehead has an angle to (not straight). The break varies from breed to breed and breed standard to breed standard. In the Abyssinian cat it is a noticeable but not profound nose break.

Beagle

The Beagle is a small hound bred for hunting rabbit and hare. The head is somewhat lengthy and is domed at the occiput. Eyes are hazel or deep brown in color, large and set apart with a soft, "pleading" expression that is common to most hounds. The finely textured ears are long, low set and gently rounded at the tips. The medium-length muzzle is square and straight with a somewhat defined stop. The shoulders and chest are broad and muscular, without being bulky. The well-muscled back is short and the loin is wide and gently arched. The gaily carried tail is high-set with a light curve, and is rather short when compared to the Beagle's size. Coloring can be any true hound color. The length of the coat is medium/close and the texture is coarse.


Temperament: The Beagle is extremely friendly and gentle—traits that make fit very well in a family environment. Beagles are perfect for families with children, as they are tolerant, loving and playful. They can be kept in homes with other animals but must be socialized early because of their hunting instincts. The Beagle can live indoors but requires a fenced yard in which to roam in addition to a daily walk. The Beagle does not like to be left alone, so owners would be well advised to keep a companion animal with their Beagle, especially when away. It is important that a Beagle is walked on a leash in order to prevent it from running off in pursuit of intriguing scents. This breed responds well to obedience training if worked with regularly. Potential owners should also keep in mind that the Beagle was bred to have a strong, melodious bark/howl for hunting purposes—a characteristic that may potentially disturb neighbors.

Habitat & Exercise: Beagles are quite small, it can accomadate itself in small living space such as apartments. A small yard is sufficient for playing with childrens and have a routine exercise.
Energetic and possessing great stamina, the Beagle needs plenty of exercise, including a brisk daily walk. It should have a fenced yard of reasonable size to romp in. Always use a lead when walking this breed or you will be running the risk of it disappearing in search of wild game.

Grooming: The Beagle's smooth short-haired coat is easy to look after. Brush with a firm bristle brush, and bathe with mild soap only when necessary. Dry shampoo occasionally. Be sure to check the ears carefully for signs of infection and keep the nails trimmed. This breed is an average shedder.

Colouring:
Beagles appear in a range of colours. Although the tricolour (white with large black areas and light brown shading) is the most common, Beagles can occur in any hound colour.
Tricoloured dogs occur in a number of shades, from the "Classic Tri" with a jet black saddle (also known as "Blackback"), to the "Dark Tri" (where faint brown markings are intermingled with more prominent black markings), to the "Faded Tri" (where faint black markings are intermingled with more prominent brown markings). Some tricoloured dogs have a broken pattern, sometimes referred to as pied. These dogs have mostly white coats with patches of black and brown hair. Tricolour Beagles are almost always born black and white. The white areas are typically set by eight weeks, but the black areas may fade to brown as the puppy matures. (The brown may take between one and two years to fully develop.) Some Beagles gradually change colour during their lives, and may lose their black markings entirely.

Two-colour varieties always have a white base colour with areas of the second colour. Tan and white is the most common two-colour variety, but there is a wide range of other colours including lemon, a very light tan; red, a reddish, almost orange, brown; and liver, a darker brown, and black. Liver is not common and is not permitted in some standards; it tends to occur with yellow eyes. Ticked or mottled varieties may be either white or black with different coloured flecks (ticking), such as the blue-mottled or bluetick Beagle, which has spots that appear to be a midnight-blue colour, similar to the colouring of the Bluetick Coonhound. Some tricolour Beagles also have ticking of various colours in their white areas.

Types of Breed: The American Kennel Club and the Canadian Kennel Club recognize two separate varieties of Beagle: the 13-inch (330 mm) for hounds less than 13 inches (33 cm), and the 15-inch (380 mm) for those between 13 and 15 inches (33 and 38 cm). The Kennel Club (UK) and FCI affiliated clubs recognize a single type, with a height of between 13 and 16 inches (33 and 41 cm).

Great Dane

A "gentle giant," the Great Dane is nothing short of majestic. Sometimes referred to as the "king of dogs," this extremely large dog breed is known for being strong yet elegant, with a friendly, energetic personality. Striking in the show ring, this breed is also popular as a family pet. Coat colors can be brindle, fawn, blue, black, harlequin and mantle.

The Great Dane is a giant dog that combines nobility with robustness and power with elegance. It has a long narrow head with an accentuated frontal stop and a rather large nasal canal. Its neck is long and muscular and its front legs are perfectly straight. It has muscular thighs and round feet with short, dark nails. The Great Dane's tail is medium-length, reaching to the point of the hock. Its eyes are round and usually dark - with a lively intelligent expression. Its ears are either cropped rather long, pointed, and carried erect, or left natural. Its well developed white teeth must close in a scissors bite.

All Danes have short, thick, shiny, close-fitting hair. The color of the coat indicates the variety, fawn, brindle, black, blue, mantle harlequin and sometimes merle. Although not a recognized color, chocolate does occur in a recessive gene. Merle is a common result of harlequin breeding, but it is not a recognized color. Black coats and dark eyes, while blue Danes may have lighter eyes.

Size, Proportion, Substance: The male should appear more massive throughout than the bitch, with larger frame and heavier bone. In the ratio between length and height, the Great Dane should be square. In bitches, a somewhat longer body is permissible, providing she is well proportioned to her height. Coarseness or lack of substance is equally undesirable. The male shall not be less than 30 inches at the shoulders, but it is preferable that he be 32 inches or more, providing he is well proportioned to his height. The female shall not be less than 28 inches at the shoulders, but it is preferable that she be 30 inches or more, providing she is well proportioned to her height. Danes under minimum height must be disqualified.

Temperament: The Great Dane is a gentle giant. Dignified, kind, sweet and affectionate, it is playful and patient with children. It loves everyone and needs to be around people. The Great Dane does not bark much and only becomes aggressive when the circumstances require it. A steady dog, responsible and dependable. Brave and loyal, it is a good watchdog. Because of his giant size, the Great Dane should be thoroughly obedience trained when young so it will be manageable when fully grown. Teach this giant dog not to lean against people, especially children. The objective in training this dog is to achieve a pack leader status. It is a natural instinct for a dog to have an order in their pack. When we humans live with dogs, we become their pack. The entire pack cooperates under a single leader. Lines are clearly defined. You and all other humans must be higher up in the order than the dog. That is the only way your relationship can be a success. Dogs who know their place below humans in the pack order will be good with children. If you are not a firm, confident, consistent pack leader who knows how to correct the dog when he is showing signs of aggression, the dog can be dog-aggressive, especially with same sex dogs.

Grooming: The smooth short-haired coat is easy to groom. Comb and brush with a firm bristle brush and dry shampoo when necessary. Bathing this giant is a major chore, so it pays to avoid the need by daily grooming. The nails must be kept trimmed. This breed is an average shedder.

Color, Markings and Patterns Brindle--The base color shall be yellow gold and always brindled with strong black cross stripes in a chevron pattern. A black mask is preferred. Black should appear on the eye rims and eyebrows, and may appear on the ears and tail tip. The more intensive the base color and the more distinct and even the brindling, the more preferred will be the color. Too much or too little brindling are equally undesirable. White markings at the chest and toes, black-fronted, dirty colored brindles are not desirable.

Fawn--The color shall be yellow gold with a black mask. Black should appear on the eye rims and eyebrows, and may appear on the ears and tail tip. The deep yellow gold must always be given the preference. White markings at the chest and toes, black-fronted dirty colored fawns are not desirable.

Blue--The color shall be a pure steel blue. White markings at the chest and toes are not desirable. The one in the beginning of the

Black--The color shall be a glossy black. White markings at the chest and toes are not desirable.

Harlequin--Base color shall be pure white with black torn patches irregularly and well distributed over the entire body; a pure white neck is preferred. The black patches should never be large enough to give the appearance of a blanket, nor so small as to give a stippled or dappled effect. Eligible, but less desirable, are a few small gray patches, or a white base with single black hairs showing through, which tend to give a salt and pepper or dirty effect.

Mantle--The color shall be black and white with a solid black blanket extending over the body; black skull with white muzzle; white blaze is optional; whole white collar is preferred; a white chest; white on part or whole of forelegs and hind legs; white tipped black tail. A small white marking in the blanket is acceptable, as is a break in the white collar.

Any variance in color or markings as described above shall be faulted to the extent of the deviation. Any Great Dane which does not fall within the above color classifications must be disqualified.

Exercise:
Although Great Danes have a fairly slow metabolism they need daily exercise the same as any other dog, and a fair amount of it. A common misconception is that they are slow and docile and don't need walking; this is incorrect and in most cases Great Danes are full of energy and need regular walking. The Great Dane was bred to hunt wild boar and guard the manor. They are robust, alert and agile when needed to be.

Health:
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. Great Danes have some health problems that are common to large breeds. Not a long lived breed. Be careful to buy from a conscientious breeder, as some very poor specimens are being sold to the unsuspecting public. Beware of hip dysplasia; buy only from OFA certified stock. Also prone to bloat, tumors, heart disease, and tail injuries. Do not jog with this dog until it is at least one year old.

Mastiff

The Old English Mastiff is one of the heaviest breeds; a male Mastiff can exceed 200 pounds. This dog is very massive, powerful and muscular. The head is heavy and square with a short muzzle. There is a black mask around the eyes and nose no matter what the general coat color. The eyes are small, dark, and hazel. The small ears should also be dark-colored. The teeth should meet in a scissors or slightly undershot bite. The tail is set quite high, tapers to the tip, and reaches to the hocks. The short coat comes in golden fawn, light fawn, brindle, silver, tiger, and apricot and is easy to groom. In the eighteenth century it was described as follows:
"As a lion is to a cat, so is a mastiff compared to a dog."

Guinness Book of World Records recognizes a mastiff from England named Zorba as the heaviest dog in the world, at over 343lb (156 kg). Zorba stood 37 inches (94 cm) at the shoulder and was 8 feet 3 inches (251 cm) from the tip of his nose to the tip of his tail[citation needed]. Zorba set this record in November 1989, when he was 8 years old, and about the size of a small donkey. There is a picture of a Neopolitan Mastiff circulating online being walked next to a small horse and the two animals are the same size. This is a doctored photo and there is no evidence in history of a dog of this magnitude. According to the Guiness Book of World Records, the tallest dog is a Great Dane named Gibson. The dog is 42.3 inches tall.

Temperament: Originally valued for their abilities as a fierce guard and fighting dog, today's Mastiff is a gentle giant. It is a self-confident, watchful, and patient dog who is gentle-natured towards his family. Intelligent and dignified. It rarely barks, but it is in its nature to defend its territory and family. Calm, steady and docile, this dog is normally excellent with children, (not recommend for toddlers though, because of their great size). Good natured, but very large and heavy. Responds well to gentle, patient training. This breed loves to please and needs lots of companionship. The breed is innately good natured, calm, easygoing, and surprisingly gentle. It is a well-mannered house pet but needs sufficient room for exercise and activity. The Mastiff is an extremely loyal breed, exceptionally devoted to its family and good with children.

The Mastiff's dominance varies widely depending on the lineage. They can be aloof with strangers or fairly friendly. Do not hit a Mastiff or you are asking for it! A born guard dog, brave and loyal. When strangers visit, it is likely to refuse to let them in unless they are accepted by its handler. The Mastiff generally holds intruders at bay rather than attacking. Protection training is unnecessary for this naturally protective breed. It is very possessive of home, family and car. It may be combative with other dogs if not very well socialized as a puppy, so extra effort should be given to socialize a Mastiff puppy. If properly socialized it will get along well with other dogs. The Mastiff tends to drool, wheeze and snore loudly. They can be somewhat difficult to train.

Grooming: The smooth, short-haired coat is easy to groom. Brush with a firm bristle brush and wipe over with a piece of toweling or chamois for a gleaming finish. Bathe or dry shampoo when necessary. This breed is an average shedder.

Health:
The mastiff is a particularly large dog demanding correct diet and exercise. Excessive running is not recommended for the first two years of the dog's life. However, regular exercise must be maintained throughout the dog's life in order to discourage slothful behavior and to prevent a number of health problems. A soft surface is recommended for the dog to sleep on in order to prevent the development of calluses, arthritis, and hygroma (an acute inflammatory swelling). Due to the breed's large size, puppies may potentially be smothered or crushed by the mother during nursing. A whelping box, along with careful monitoring can prevent such accidents. The expected lifespan is about 7 to 13 years.

Beware of hip dysplasia. As these dogs are prone to bloat, feed two or three small meals a day, instead of one large one. Also prone to CHD, gastric torsion, ectropion, PPM, vaginal hyperplasia, elbow dysplasia and PRA. Occasionally seen is cardiomyopathy.

English Mastiff history: The Mastiff name probably evolved from the Anglo-Saxon word masty, meaning powerful. The Mastiff is descended from the ancient Alaunt and Molosser and is recognized at the oldest British breed. The Mastiff might have been brought to Britain in the 6th century BC. It was used in the blood sports of bear-baiting, bull-baiting, dog fighting, and lion-baiting. Throughout its long history, the Mastiff has contributed to the development of a number of dog breeds.

When Sir Peers Legh was wounded in the Battle of Agincourt, his Mastiff stood over and protected him for many hours through the battle. Although Legh later died, the Mastiff returned to Leghs home and was the foundation of the Lyme Hall Mastiffs. Five centuries later this pedigree figured prominently in founding the modern breed.
Some evidence exists that the Mastiff came to America on the Mayflower, but the breeds documented entry to America did not occur until the late 1800s. In 1835, Britain passed legislation making baiting illegal. Subsequently, the Mastiff lost popularity and was virtually decimated in England by the Second World War; however, sufficient numbers had been brought to America by that time to keep the breed going. Since that time, it has gradually risen in popularity.

This picture from the mastiff images available in the web shows clearly how big and macho a Mastiff will be when compared with human.













Pug

One of the great things about pugs is their size. The Pug is a small breed of dog with a wrinkly, short muzzled face . Pugs are small dogs, but their small size is deceptive, they pack a punch! The word "pug" may have come from the Old English pugg or "puge", which were affectionate terms for a playful little devil or monkey. Adult pugs vary in weight from approximately 17 to 24 lbs, the females on the lower end of the scale. An adult pug is only about the size of a big cat.
They say that pugs are a big dog in a little package and it's true. They are not fru-fru dogs that are delicate or require a lot of primping and preening.
Pug puppies are often called puglets. The breed is often summarized as multum in parvo ("much in little"), describing the Pug's remarkable personality despite its small size.

Temperament: Pugs are friendly, playful dogs with wonderful temperaments. They are natural clowns and will keep you entertained.
They are wonderful with children and older people too. I have never seen a pug act out aggressively towards any person. I have two unneutered male pugs who get into occasional scrapes with each other, but only very rarely with other dogs and only then with other unneutered males. They get along well with other dogs, even much larger dogs. I have never known pugs to be intimidated by any other breeds and are good playmates at the park. Pugs are very loving and will follow their owner wherever they go.

Training: Pugs are very smart and stubborn dogs. They can be trained with a little persistence and patience. Pugs will do anything for food. Training with a treat or a toy and lots of praise seems to work the best for me. Start training right away. Instead of training in one long session that can get boring and frustrating to the dog, train in short 5-10 minute sessions throughout the day. This keeps training fun for your pug. The following are the most important things for your pug to learn. Pugs are sensitive to the tone of a human voice, so harsh punishment is generally unnecessary. While Pugs usually get along well with other dogs and pets, they generally prefer the company of humans and require a great deal of human attention; they may become slightly anxious or agitated if their owner ignores them or does not play with them. In general, they are very attentive dogs, always at their owner's feet, in their lap, or following them from room to room.

Types of pugs: It is common today to see a few different types of pugs around the place. Many people will know about black pugs and the common white pug, but many have never heard of the Chinese pug. The Chinese pug is in fact exactly the same as the Western pug but many people traditionally call them the Chinese pug because that is there proper name. This is usually the hardcore breeders whose livelihood is based around breeding the most traditional looking pugs possible. Most breeders in fact are so traditional that they actually believe that the pugs they have are the original Chinese pugs because of their difference in appearance.

First one is the chinese pug, second is the black pug, third is also chinese, and the one in the beginning is the fawn pug. I love black pugs the most.

Flemish Giant

Flemish Giant is a type of rabbit, most famous for its unusually large size compared to other rabbits.

Flemish giants come in seven varieties recognized by the American Rabbit Breed Association(ARBA): black, blue, fawn, light gray, sandy, steel gray, and white. They are shown in six classes (three buck classes and three doe classes): Junior bucks and does under 6 months, Intermediate bucks and does 6-8 months, and Senior bucks and does 8+ months. The show classifications under the ARBA Standard of Perfection declare that Juniors should be 6 pounds and over, Senior bucks a minimum of 13 lbs, and Senior does to be 14 lbs. There is no maximum size, however, and they commonly attain weights in excess of 22 lbs.

No one knows the exact origins of the Flemish Giant breed. Some suggest that the during the 16th and 17th century, Dutch Traders may have brought giant Patagonian rabbits from the Argentine Republic back to Europe with them. The large rabbits of Flanders were well known at the time, and may have been cross bred with the Patagonian. While the name "Flemish" comes from Flanders, the similarities to the Patagonian lead many to speculate that this giant is in fact descended primarily from the wild Argentine rabbits.

Why do pigeons bob their heads when they walk?

Most evidence suggests that the head bobbing serves a visual function.

See video: http://in.youtube.com/watch?v=NHtrsbw3K0g

This has always been an intriguing phenomenon. Pigeons (or ‘Rock Pigeons’ to be exact) have a peculiar habit of bobbing their heads up and down when they walk. This leads to a common misconception – that the legs of a pigeon are somehow connected to their heads. When they walk, they move their heads up and down; when they stand still, there is no movement!

Birds have eyes on either side of their head, so don't have stereoscopic vision. In order to see depth, they take snapshots with the same eye from two points, and their mind makes the depth calculation.

In order to shed more light on this conundrum, one must first understand the basics of ‘bird vision’. From Ornithology (the science of birds), it can be inferred that as the pigeon’s eyes are on the side of its head – allowing a greater range of vision to stay vigilant against predators from all directions – they also disable the pigeon from its sense of depth. Pigeons cannot establish distances easily. Luckily we humans have eyes on the front of our heads, giving us depth perception.

For the pigeon to compensate this shortcoming, the bird moves its head, deciding on differences in apparent motion from nearby and/or distant objects. Closer objects move faster, distant objects move slower.

Now when rock pigeons stop in one place, there is no requirement for depth perception, hence the cessation of the head bobbing. But once they start foraging for food again, the need for depth kicks in and they start moving their heads up and down – giving the illusion that their heads are somehow connected to their feet!

To illustrate this concept, here is a common example: In the past, you may have tried to shoo away a pigeon in an outdoor picnic area. When a hand is wafted towards the pigeon, it turns sharply head first – in a desperate attempt to ascertain the depth of the attack – before attempting to fly/walk away. It all happens very quickly, but look out for it next time!

Chickens bob their heads while walking. So do cranes, magpies and quails. In fact, head bobbing is a unique feature in birds and occurs in at least 8 of the 27 families of birds.

There are a few theories why some birds bob their heads when they walk:
1. Assists with balance
2. Provides depth perception
3. Sharpens their vision

However, most studies suggest that birds in motion bob their heads to stabilize their visual surroundings. In comparison, we rely more on our eye movements, not our head movements, to catch and hold images while in motion.

Picture a pigeon on a moving treadmill. What do you think would happen as the pigeon walks with the speed of the treadmill and its environment remains relatively the same? Dr. Barrie J Frost (1978) did this experiment and the pigeon’s head did not bob.

Dr. Mark Friedman (1975) also conducted a series of experiments to test the head bobbing actions of birds, using doves. His research demonstrated that the head movement is controlled more by visual stimulation than movement of the body.

Scientists continue to research head bobbing in birds. For example, scientists are currently investigating question such as “Why do some birds exhibit head bobbing, while other do not?” For more information on this topic see the related Web sites section.
