Breed: Pekingese
The Pekingese or Peke (also commonly referred to as a "Lion Dog", "Pelchie Dog", or "Foo (or Fu) Dog" due to their resemblance to Chinese guardian lions) is an ancient breed of toy dog, originating in China. They were the favored pet of the Chinese Imperial court, and the name relates to the city of Beijing where the Forbidden City resides. The breed has several characteristics and health issues related to its unique appearance.
Appearance 
The Pekingese breed is over 2000 years old and has hardly changed in all that time. One exception is that modern breeders and dog-show judges seem to prefer the long-haired type over the more-traditional spaniel-type coat.
The Pekingese's flat face is one of the breed's most obvious characteristics. The body is compact and low to the ground. The legs are noticeably bowed and restrict the Pekingese's movement. The Peke's unusual rolling gait may have been deliberately bred to prevent the court dogs from wandering.
Coat
A Pekingese has a double coat. Trimming the coat is discouraged in show dogs. The Pekingese has a noticeable mane and feathering around the ears, tail and legs.
All breed standards allow all sorts of color combinations. The majority of Pekingese are gold, red or sable. Light gold, cream, black, white, sables, black and tan and occasionally 'blue' or slate grey have appeared in the breed. The latter often has poor pigment and light eyes. Albino Pekingese (white with pink eyes) should be bred cautiously due to health problems that have been associated with albinism.
A black mask or a self-colored face is equally acceptable in show dogs. Regardless of coat color the exposed skin of the muzzle, nose, lips and eye rims is black.
Coat
Pekes weigh from 7 to 14 lb (3.2 to 6.4 kg) and stand about 6–9 inches (15–23 cm) at the withers, however they can sometimes be smaller. These smaller Pekes are commonly referred to as "Sleeve" Pekingese or just "Sleeves". The name is taken from ancient times, when emperors would carry the smallest of the breed in their sleeves. A Pekingese over 14 pounds is disqualified in the show ring.
The Pekingese is slightly longer than tall when measured from the forechest to the buttocks. The overall outline is an approximate ratio of 3 high to 5 long.
Care 
Keeping the Peke coat healthy and presentable requires brushing once a day if it is an outside dog. If you do this, they will need to see a groomer only once every 3 months. If a Peke becomes dirty, it is important to take it to a groomer as soon as possible, as it is difficult to remove dirt from its coat once it has dried, but this can be avoided by brushing regularly, especially the belly, and between the front and hind legs. One important thing for new owners to remember is that dogs intended as a house pet may be kept in a puppy cut which is much more low maintenance than a show cut. It is also important to remove dirt from the eye pores daily, and from the creases on the face to prevent sores (hotspots).
Due to their abundance of fur, it is important to keep the Pekingese cool. Pekes are indoor dogs and they are prone to having heatstroke when exposed to high temperature.
History 
The breed originated in China in antiquity, in the city of Peking most likely from Asian wolves. Recent DNA analysis confirms that the Pekingese breed is one of the oldest breeds of dog, one of the least genetically diverged from the wolf. For centuries, they could be owned only by members of the Chinese Imperial Palace.
During the Second Opium War, in 1860, the Forbidden City was invaded by Allied troops. The Emperor Xianfeng had fled with all of his court. However, an elderly aunt of the emperor remained. When the ‘foreign devils’ entered, she committed suicide. She was found with her five Pekingese mourning her passing. They were removed by the Allies before the Old Summer Palace was burnt.
Lord John Hay took a pair, later called ‘Schloff’, and ‘Hytien’ and gave them to his sister, the Duchess of Wellington, wife of Henry Wellesley, 3rd Duke of Wellington. Sir George Fitzroy took another pair, and gave them to his cousins, the Duke and Duchess of Richmond and Gordon. Lieutenant Dunne presented the fifth Pekingese to Queen Victoria of the United Kingdom, who named it Looty.
The Empress Dowager Cixi presented Pekingese to several Americans, including John Pierpont Morgan and Alice Lee Roosevelt Longworth, daughter of Theodore Roosevelt, who named it Manchu. The first Pekingese in Ireland was introduced by Dr. Heuston. He established smallpox vaccination clinics in China. The effect was dramatic. In gratitude, the Chinese minister, Li Hung Chang presented him with a pair of Pekingese. They were named Chang and Lady Li. Dr. Heuston founded the Greystones kennel.
Peke legends
There are two origination stories for the Pekingese. The first is the most common, The Lion and the Marmoset:
A lion and a marmoset fell in love. But the lion was too large. The lion went to the Buddha and told him of his woes. The Buddha allowed the lion to shrink down to the size of the marmoset. And the Pekingese was the result.
The second, less-common, originating story is The Butterfly Lions:
A lion fell in love with a butterfly. But the butterfly and lion knew the difference in size was too much to overcome. Together they went to see the Buddha, who allowed their size to meet in the middle. From this, the Pekingese came.
Another legend says that the Peke resulted from the mating of a lion and a monkey, getting its nobleness and coat from the former and its ungainly walk from the latter.
Because the Pekingese was believed to have originated from the Buddha, he was a temple dog. As such, he was not a mere toy. He was made small so that he could go after and destroy little demons that might infest the palace or temple. But his heart was big so that he could destroy even the largest and fiercest. (A book was written from this premise, although the author denies knowledge of the legends: Bride of the Rat God.)
