The merle coat pattern, which appears mottled, is not traditionally considered part of the breed standard. In May 2007, The Kennel Club decided not to register puppies with this coloration due to the health risks associated with the responsible gene, and in December of that year, formally amended its breed standard to disqualify merle dogs.[20] The Fédération Cynologique Internationale, which represents the major kennel clubs of 84 countries, also disqualified merle.[16] Other countries' kennel clubs, including Canada, Australia, New Zealand, and Germany, have also disqualified merle. However, in May 2008, the Chihuahua Club of America voted that merles would not be disqualified in the United States, and would be fully registrable and able to compete in AKC events. Opponents of merle recognition suspect the coloration came about by modern crossbreeding with other dogs and not by natural genetic drift.[21][citation needed]
In a 1520 letter, Hernan Cortés wrote that the Aztecs raised and sold the little dogs as food.[7] Colonial records refer to small, nearly hairless dogs at the beginning of the 19th century, one of which claims 16th-century Conquistadores found them plentiful in the region later known as Chihuahua.[8] Small dogs such as Chihuahuas were also used as living heating pads during illness or injury. Some believe this practice is where the idea of pain being transferred to animals from humans originated, which gave way to rituals such as burning the deceased with live dogs, such as the Techichi, to exonerate the deceased human's sins.[9] Chihuahuas as we know them today remained a rarity until the early 20th century; the American Kennel Club (AKC) did not register a Chihuahua until 1904.[10]
According to the American Temperament Test Society[1], the Pit Bull is second only to the Labrador Retriever in terms of temperament. The test was carried out on as many breeds as possible, administering and recording the test to find out which breeds met the highest standards in terms of temperament. This involved meeting oddly dressed strangers, firing guns to potentially spook them, walking on uncomfortable surfaces and more. They are carried out by professionals and are repeated as much as possible.
Pit bulls also constitute the majority of dogs used for illegal dog fighting in America.[10] In addition, law enforcement organisations report these dogs are used for other nefarious purposes, such as guarding illegal narcotics operations.[11][12] use against police,[13] and as attack dogs.[14] On the other side of the law, pit bulls have been used as police dogs.[15][16]
The ancestors to the Chihuahua nearly became extinct during the 1500s, when the Aztec Empire was decimated by Hernán Cortés and the Spanish colonizers. In 1850, three small dogs -- now thought to be modern versions of the Chihuahua -- were discovered in the Mexican state of Chihuahua, from which breed gets its name. Border states within the United States, such as Texas, Arizona and New Mexico, soon began to see a massive import of the dog breed. However, it wasn't until the Rhumba King, Xavier Cugat, began appearing in films carrying a Chihuahua dog in the early 1900s, that the breed gained its celebrity. Today, it has emerged as one of the most popular breeds in the United States.
A disease that seems to be increasing among Chihuahuas is GME, which stands for Granulomatous Meningoencephalitis. It is becoming more frequent among the apple head Chis. It is, at this time, a very poorly understood central nervous system disease that suddenly strikes without much warning. It comes in three types: focal (lesions in the brain or spine); multifocal (lesions in both brain and spine as well as eyes); and optical (causing blindness. There are several current methods of treating it currently and which continue to be updated as more research is done. While there are methods of controlling it in those dogs who survive the first two weeks, unfortunately, there is no true cure. It can go into remission, sometimes for years, but can always resurface. The medications, testing, etc. in the beginning in order to properly diagnose, the cost is in the thousands and many, many more thousands will need to be spent over the remaining years of the dog's life. While GME occurs in many other breeds (generally the toy breeds though there are some others, there is a tremendous number of Chihuahuas with it. Interestingly, deer head Chihuahua's do not tend to be prone to GME, only the apple-head type.
Beagles are active, energetic dogs who need at least an hour of exercise every day. This doesn’t mean just letting them out in the backyard. Beagles were bred to work in packs and are happiest when they have company. A Beagle who is left alone inside or outside for long periods of time will tend to become destructive. This can be avoided if he has a companion (whether human or canine) to play with. Beagles are escape artists, so an exercise area must have a fence at least five feet tall that extends underground to prevent tunneling. Walks must always be taken on a leash, because as a scenthound with a very strong hunting instinct, a Beagle will not be able to resist the urge to run off in pursuit of a compelling scent.
Finding a good breeder is the key to finding the right puppy. A good breeder will match you with the right puppy, and will without question have done all the health certifications necessary to screen out health problems as much as possible. He or she is more interested in placing pups in the right homes than making big bucks. Good breeders will welcome your questions about temperament, health clearances and what the dogs are like to live with and come right back at you with questions of their own about what you’re looking for in a dog and what kind of life you can provide for him. Most breeders like to keep the pups until they are 12 to 14 weeks old to ensure that they are mature enough to go to their new homes.

They are a cross between the Old English black and tan terriers (Welsh terrier) and the otterhounds. They are tall and have a very lovable expression, medium hair on the body, and a long elongated face. They have a curly and rough coat, and a soft undercoat. The color is a black and tan combination. During the early 19th century, these dogs were used for sporting events which featured catching of large river rats; hence they possess an instinct to chase small animals. During World War I, these dogs were also used by the armed forces as messengers for mails, and to find wounded soldiers behind enemy lines. Overall, they are loyal, caring, and will guard you and your family.


Your American Pit Bull Terrier must be kept on leash in public to prevent aggression toward other dogs. It's not a good idea to let these dogs run loose in dog parks. While they might not start a fight, they'll never back down from one, and they fight to the finish. American Pit Bulls who aren't properly socialized as puppies can become aggressive toward other dogs.
A very common misconception is that APBTs are muscle-bound hulks that weigh in around 85 pounds (39 kg) or more and this is generally not the majority. Most of the APBT's that are that large have been crossed with other breeds and are being called American Bullies. The general public often gets American Bullies mixed up with the American Pitbull Terriers. American Pitbull Terrier vs. American Bully
With the mining industry growing steadily into the 17th century, Chihuahua was named the capital of the province of Nueva Vizcaya. From 1640 to 1731, the area experienced increased economic activity and, concomitantly, frequent indigenous uprisings. Tensions developed between the miners and the hacienda owners who continued to force indigenous groups into slavery.

By 1887 the threat of extinction was on the wane: there were 18 beagle packs in England.[14] The Beagle Club was formed in 1890 and the first standard drawn up at the same time.[15] The following year the Association of Masters of Harriers and Beagles was formed. Both organisations aimed to further the best interests of the breed, and both were keen to produce a standard type of beagle.[16] By 1902, the number of packs had risen to 44.[14]
These dogs are extremely intelligent and learn commands and tricks with ease. They have a zest for life and love to be involved in everything going on around them. They maintain a puppyish demeanor well into adulthood, and that vitality makes them a joy to live with. Once you have met and gotten to know this breed you will wonder how you ever lived without one.
