The Chihuahua is very small-sized dog. It has always been a popular and an adorable dog, loved and owned by many celebrities. There are ongoing debates about the origin of the Chihuahua. Some argue that an old Aztec civilization was the origin of Chihuahua, while some others assert that it came from ancient Egypt. While the former group explains that the Chihuahua was actually brought by Spanish settlers to Mexico from old Aztec, and then it came to the United States, the later group suggests it made its way from Egypt to Spain via Mexico.

Long haired Chihuahuas looks very similar to Pomeranians. The hair of the long haired Chihuahua is commonly known as "long coats" or "smooth coats". With their apple-shaped head, big eyes and tasseled ears, they look simply exquisite. They are the smallest dog in the world. Their size may vary between six inches and nine inches. Show dogs may weigh less than six pounds in average, however the weight of the normal pet dog may be as high as ten pounds or more.

While considering temperament and personality, there is no distinction between the short haired and long haired Chihuahua. Both of them are very loving and affectionate. They have a jovial personality on one hand and also a very alert type on the other. They are the most preferred pets for the elderly and disabled people because of their friendliness and socialization. This breed also has a negative reputation of being very stubborn and van be tough to train. However, following a successful training, this breed turns out to be an excellent pet.

Although it belongs to the Toy group, many standard breeders do not recommend either short or long haired Chihuahua for households with small children. They go very well with adults and offer nice companionship. Due to their small size and fragile bone structure a long haired Chihuahua must be handled very carefully, otherwise there is always a risk for potential injury. They can make friendships very easily with other breeds and animals, such as cats and dogs from other breeds.

Both the short and long haired Chihuahua can not tolerate cold temperatures. They need to wear coats or sweaters to feel comfort during the winter and spring seasons. Like any other long haired breeds, long haired Chihuahuas need proper grooming and utmost care. If the dog does not receive proper grooming and care, the hair will become full of knots, mats and burs and the hair will lose its shine.

Similar to any other long haired breeds, the long haired Chihuahua demands extensive grooming in order to maintain the luster in its wavy hair. Regular care of the hair is necessary to eliminate knots, mats and burs as well as to keep them free from ticks and hitchhikers. Monthly bathing with residue-free shampoo is mandatory.

From a genetic angle, short hair is dominant over long hair. If both the partners are long haired Chihuahua, only then is it possible to have long haired Chihuahuas as offspring. It is the responsibility of the professional breeders to keep good breeding records of their long haired Chihuahuas, so that the highest quality in offspring can be effectively maintained.

They need to maintain an excellent record of each of the dog of this variety in order to ensure the high quality of the breed as well as to customize certain textures over the long coat. When the pedigree is properly documented, the price increases dramatically.
