The Chihuahua's history is convoluted, and many theories surround the origin of the breed. Both folklore and archaeological finds show that the breed has origins in Mexico. The most common theory is that Chihuahua are descended from the Techichi, a companion dog favored by the Toltec civilization in Mexico. No records of the Techichi are available before 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. The earlier ancestors probably were present before the Mayas as dogs approximating the Chihuahua are found in materials from the Great Pyramid of Cholula, antedating 1530 and in the ruins of Chichen Itza on the Yucatán Peninsula. However, a genetic study indicated that there was less than 2 percent pre-European mitochondrial DNA in modern Chihuahuas due to admixture with the European dogs.
In a 2014 literature review of dog bite studies, the American Veterinary Medical Association (AVMA) states that breed is a poor sole predictor of dog bites. Controlled studies have not identified pit bulls as disproportionately dangerous. Pit bull-type dogs are more frequently identified with cases involving very severe injuries or fatalities than other breeds, but the review suggests this may relate to the popularity of the breed, noting that sled dogs, such as Siberian Huskies, were involved in a majority of fatal dog attacks in some areas of Canada. Bite statistics by breed are not tracked by the CDC, AVMA or the American Society for the Prevention of Cruelty to Animals (ASPCA). State Farm Insurance spokeswoman Heather Paul stated "Pit bulls in particular are often misidentified when a bite incident occurs, so reliable bite statistics related to the dogs’ breed are unreliable and serve no purpose." The White House stated that "the Centers for Disease Control and Prevention looked at twenty years of data about dog bites and human fatalities in the United States. They found that fatal attacks represent a very small proportion of dog bite injuries to people and that it’s virtually impossible to calculate bite rates for specific breeds". 
I had what I think was a Chihuahua/Cairn Terrier mix but not sure. Her name was Mia and she weighed 7 lbs. I got her from a shelter; she was given up by a young couple when they separated and supposedly she was bought at a puppy mill and was listed as a Chiweenie (but there’s no way!). We got her at 9 months and she was a bit difficult to potty train but we got through it. She loved her cage and got along fabulously with our Golden Retriever. They were buddies. Unfortunately, she darted into the street and someone hit her; she died instantly. I am devastated because she truly was the BEST dog I’ve ever had. She had a HUGE personality for such a tiny dog and she was a loving snuggler who was always there when you needed her. She was killed this week and I am inconsolable. I want another one but I have no idea where to begin.
The American Pit Bull Terrier (APBT) has a strong desire to please. The APBT has evoked more human emotional, rational and irrational response than any other breed that exists today. By no means are these dogs people-haters or people-eaters. Their natural aggressive tendencies are toward other dogs and animals, not people. However if they are properly socialized with a firm, but calm, confident, consistent pack leader, they will not even be aggressive with them. The American Pit Bull Terrier is a good-natured, amusing, extremely loyal and affectionate family pet that is good with children and adults. Almost always obedient, it is always eager to please its master. It is an extremely courageous and intelligent guard dog that is very full of vitality. Highly protective of his owners and the owner's property, it will fight an enemy to the death. It is usually very friendly, but has an uncanny ability to know when it needs to protect and when everything is okay. The American Pit Bull Terrier can be willful with meek owners and needs a firm hand. They are generally okay with other pets if they are raised with them from puppyhood. They are very friendly, but not recommended for most people, because most people do not understand how to properly raise and treat a dog. Problems arise when one does not understand natural dog behavior, seeing the dog as having human emotions, and ends up with a dog who thinks he is the boss of the house. For a smaller, not as powerful dog, people can sometimes get away with this, however, for a powerful breed, one really needs to understand and follow this concept of keeping a dog. Excellent with children in the family, they have a high pain tolerance and will happily put up with rough child play. As with any breed, they should not be left alone with unfamiliar children. Used as all-around working farm dogs, they were referred to as "the poor man’s horse." Later they were used as fighting dogs; the powerful American Pit Bull may go for the throat of strange dogs. A minimum of training, along with the proper amount of exercise and a firm pack leader, will produce a tranquil, obedient dog. Socialize very thoroughly when young to combat aggressive tendencies and be sure to keep the dog under control when other dogs are present. Teach this dog respect for humans by not allowing it to jump up and not allowing it to enter doorways first. The humans must make the dog heel beside or behind them when walking. It has given outstanding results as a guardian of property, but is at the same time esteemed as a companion dog. The objective in training this dog is to achieve pack leader status. It is a natural instinct for a dog to have an order in its pack. When we humans live with dogs, we become their pack. The entire pack cooperates under a single leader; lines are clearly defined and rules are set. 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. When properly trained and socialized, this is a very good dog and a great family companion. Unfortunately, some choose to promote the fighting instinct in the breed, giving it a bad name.
Pet Chihuahuas (that is, those bred or purchased as companions rather than show dogs) often range above these weights, even above 10 lb if they have large bone structures or are allowed to become overweight. This does not mean that they are not purebred Chihuahuas; they just do not meet the requirements to enter a conformation show. Oversized Chihuahuas are seen in some of the best, and worst, bloodlines. Chihuahuas do not breed true for size, and puppies from the same litter can mature in drastically different sizes from one another. Also, larger breeding females are less likely to experience dystocia (obstructed labour). Many breeders try to breed Chihuahuas as small as possible, because those marketed as "teacup" or "tiny teacup" command higher prices. Typically, the breed standard for both the Long and Short Coat Chihuahuas will be identical except for the description of the coat. Chihuahuas have large, round eyes and large, erect ears, set in a high, dramatically rounded skull.
In the 1840s, a standard beagle type was beginning to develop; the distinction between the North Country Beagle and Southern Hound had been lost, but there was still a large variation in size, character, and reliability among the emerging packs. In 1856, "Stonehenge" (the pseudonym of John Henry Walsh), writing in the Manual of British Rural Sports, was still dividing beagles into four varieties: the medium beagle; the dwarf or lapdog beagle; the fox beagle (a smaller, slower version of the Foxhound); and the rough-coated or terrier beagle, which he classified as a cross between any of the other varieties and one of the Scottish terrier breeds. Stonehenge also gives the start of a standard description:
Forequarters: Shoulders – Lean, sloping into a slightly broadening support above straight forelegs that set well under, giving free movement at the elbows. Shoulders should be well up, giving balance and soundness, sloping into a level back (never down or low). This gives a well developed chest and strength of forequarters. Feet – A small, dainty foot with toes well split up but not spread, pads cushioned. (Neither the hare nor the cat foot.) Dewclaws may be removed. Pasterns – Strong.
The first mention of the Beagle in the United States occurred in the town records of Ipswich, Massachusetts, in 1642. Before the American Civil War, people in the South used Beagles, but these dogs did not resemble English Beagles. However, when the war was over, English Beagles were imported for crossbreeding and to develop the modern American Beagle we know today. The last part of the 19th century saw the emergence of Beagles as popular competitors on the field and in exhibitions. Soon thereafter, this little hound dog with the melodic howl came to be amongst the most preferred family pets in the U.S.
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.
I was sure that I had some sort of Yorkie/Cairn Terrier mix. Just on a whim and when there was a sale, I ordered a DNA kit through wisdom panel. Imagine my surprise when it came back that Piper Is 62.5% Chihuahua and 37.5% something in the sporting group. That explains the loud bark. I believe she is long-haired Chihuahua because of her thick coat. I rescued her after she was found under a dumpster. She will warm up to another animal but it takes some time.
The most important thing to know about the Beagle is that he is a scenthound. His nose is the most important part of his anatomy and his head is always down to the ground, searching for an interesting trail to follow. Beagles have approximately 220 million scent receptors compared to the paltry 5 million or so in people, which makes them very good at picking up scents. Humorist Dave Barry once described his in-laws' Beagle as "a nose with feet."
The Chihuahua, which has an average lifespan of 14 and 18 years, is known to suffer from some minor health ailments such as keratoconjunctivitis sicca (KCS), hypoglycemia, pulmonic stenosis, patellar luxation, and hydrocephalus. It is also susceptible to some severe health issues, including molera -- a hole in the Chihuahua's skull, occurring when bones in the fontanel are not firmly knit together.
Early Beagles looked different depending on the type of ground over which they were expected to hunt. Houndsmen who lived in the gentle countryside of southern England produced slow and ponderous dogs. Beagles from the rougher terrain of Britain’s border with Scotland were agile with lots of endurance. In the early nineteenth century, breeders worked to standardize the breed so they would have a more uniform appearance and temperament. But even today, they aren’t that different from the Beagles of 200 years ago. If one of those dogs were to come forward into the future, you would still recognize him as a Beagle, and the same is true if a modern Beagle were to be transported to the past.
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.
The Chihuahua is a very alert little dog of high intelligence. He is eager to please his humans and responds well to positive training practices. Chihuahuas seem well aware of how cute they are and learn how to get their way. From the very beginning you must enforce the fact that you are in charge. Never allow your Chihuahua puppy to do anything that will be unacceptable in an adult. They can have a bit of a “terrier” temperament, so a firm but gentle hand is necessary when training. They can excel in obedience training and other canine sports.
Another myth about Pit Bull type dogs is that they have a locked jaw which is impossible to break. While many of these dogs do indeed have a strong bite, it is a myth that their jaw locks. It can be broken using a bite stick or by some of the other ways mentioned in our article on breaking a Pit Bull's bite. Another important factor in Pit Bulls is the tendency to dock their tails and ears which makes it more difficult to recognize the signs of aggression in these dogs.
Some of these tendencies can be helped through early training and socialization. Unfortunately, too many people with Chihuahuas allow them to become little tyrants, displaying manners that would not be acceptable in a larger dog. This dog needs gentle and consistent training from puppyhood on to control his nipping as well as any tendency he has to fight with other dogs. Like many small dogs, Chihuahuas aren't aware of their own size and won't hesitate to challenge a dog many times larger than themselves. Also, like many small dogs, Chihuahuas are difficult to house-train without a lot of consistency and patience.
The tricolored beagle—white with large black areas and light brown shading—is the most common. Tricolored beagles 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 tricolored dogs have a broken pattern, sometimes referred to as pied. These dogs have mostly white coats with patches of black and brown hair. Tricolor 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 color during their lives, and may lose their black markings entirely.
Chihuahuas (and Chihuahua crosses and mixes) are frequently available from Dog Rescue groups. Chihuahuas may be turned over to Rescue because of housebreaking problems, or barking, or general nastiness when unsocialized or treated like babies. Other Chihuahuas are given up simply because of changed family circumstances, and these dogs may have no behavior problems at all.
The cost of a Chihuahua puppy varies depending on the breeder’s locale, whether he is male or female, whether he’s longhaired or smooth, what titles his parents have, and whether he is best suited for the show ring or a pet home. Prices can range from $400 to $1,600, sometimes higher for puppies with show potential. The cheapest puppy is not always the best, nor is the most expensive. What matters is that the puppy you buy has been raised in a clean home environment, from parents with health clearances and show titles to prove that they are good specimens of the breed. Often, breeders will have puppies spayed or neutered before placing them. Puppies should be temperament tested, vetted, dewormed, and socialized to give them a healthy, confident start in life.
How do Chihuahuas get along with dogs outside their own family? Often not well. Chihuahuas often raise a ruckus when they spy a strange dog, especially a larger dog. It's as though the Chihuahua wants to convince the larger dog that he is a force to reckon with rather than a helpless prey animal. The Chihuahua may be seeking to protect itself by putting up a blustering facade that tells the other dog to "move along."
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
Networking can help you find a dog that may be the perfect companion for your family. You can also search online for other Beagle rescues in your area. Most people who love Beagles love all Beagles. That’s why breed clubs have rescue organizations devoted to taking care of homeless dogs. The National Beagle Club’s rescue network can help you find a dog that may be the perfect companion for your family. You can also search online for other Beagle rescues in your area.
Leaping from your arms. Some Chihuahuas melt into your arms and stay there, but many are wriggly. They can be deceptive about it, too, apparently settling into your arms with contentment, then suddenly launching themselves through the air if you relax your grip. A fall from a few feet up, especially over a hard surface, can result in a broken leg or concussion. Hold on tight if you pick up a Chihuahua over concrete.
The Pit Bull’s origins can be traced back to early 19th-century England, Ireland and Scotland. The canine’s ancestors were the result of experimentally crossbreeding different Bulldog and Terrier breeds for the purpose of bear- and bull-baiting, a blood sport in which the dog was trained to attack until the larger animal was defeated. When baiting was banned in the 1800s, the dogs were then bred for the sport of ratting and dog fighting. European immigrants introduced the Pit Bull breed to North America.
Throughout the 16th century, the first Spanish settlements were established around haciendas (country estates) and mining operations. Some Franciscan missions and Carapoa villages were also founded in the mid-1500s. Although the military garrisons at El Paso and Ciudad Juárez were both built in 1598, the Spanish colonizers exerted fairly loose control over the region during most of the 16th century.
Pit bulls also constitute the majority of dogs used for illegal dog fighting in America. In addition, law enforcement organisations report these dogs are used for other nefarious purposes, such as guarding illegal narcotics operations. use against police, and as attack dogs. On the other side of the law, pit bulls have been used as police dogs.
