Look for a breeder who is a member in good standing of the Chihuahua Club of America and who has agreed to abide by the club's code of ethics. It specifies that its members should evaluate all breeding stock for hereditary faults, never sell dogs to pet stores, and take back Chihuahuas they have bred in the event that the buyer cannot keep them. The CCA lists member breeders on its website, but it’s still important to interview them before buying.
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. The Fédération Cynologique Internationale, which represents the major kennel clubs of 84 countries, also disqualified merle. 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.
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.
Due to their athleticism and diverse breeding background, the Pit Bull breed tends to be hardy, with an average lifespan of 12 to 14 years, longer than many breeds of a similar size. There are some genetic conditions to be watchful for. The Pit Bull tends to suffer from bone diseases such as hip dysplasia, degenerative myelopathy and kneecap dislocation. The Pit Bull can also suffer from skin problems, such as mange and skin allergies, because of its short coat. Other health ailments seen in Pit Bulls include thyroid and congenital heart defects.
The Chihuahua’s coat can be long with soft and straight hair, smooth with glossy and soft hair, or wavy with fringed ears. Its graceful body is compact and small, although slightly long in proportion to its height. The Chihuahua also bears a resemblance to the terrier in its alertness, attitude and lively expression. As far as its appearance, the breed can be found in solid black, solid white, with spots, or in a variety of patterns and colors.
The biggest trick to training a Beagle is to make everything you do with him seem like fun. Never try to force a Beagle to do anything, and never count on a Beagle to be obedient unless you can offer treats as an incentive. This is one breed where it’s important to keep in mind that old saying about catching more flies with honey than with vinegar.
Whether you’re planning to get your new best friend from a breeder, a pet store, or another source, don’t forget that old adage “let the buyer beware”. Disreputable breeders and facilities that deal with puppy mills can be hard to distinguish from reliable operations. There’s no 100% guaranteed way to make sure you’ll never purchase a sick puppy, but researching the breed (so you know what to expect), checking out the facility (to identify unhealthy conditions or sick animals), and asking the right questions can reduce the chances of heading into a disastrous situation. And don’t forget to ask your veterinarian, who can often refer you to a reputable breeder, breed rescue organization, or other reliable source for healthy puppies.
Reality: This is a stereotype that is biased toward generalizing and condemning an entire breed based on the actions of a few bad people. The truth is that each dog should be evaluated by his own merits and not by his breed. A corollary truth is that there truly are no bad dogs, only bad people. In his essay Troublemakers, Malcolm Gladwell discusses what Pit Bull stereotypes can teach us about the wrongness of racial profiling of both humans and dogs.
The experiment was a huge success. Because they are small, friendly, and cute, the Beagles didn't intimidate people who are afraid of dogs, and with their super nose power, they could be trained to identify specific food articles while bypassing those that weren't contraband. Today, members of the "Beagle Brigade" patrol the baggage-claim areas at more than 20 international airports and other points of entry into the United States.
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.
Because Chihuahuas get cold easily they tend to love their dens and will often burrow themselves in pillows, clothes hampers, and blankets. They are often found under the covers or at the bottom of the bed, deep in the dark and safety of what they perceive as their den. Chihuahuas also enjoy time in sunlight. Chihuahuas sometimes act like cats and climb up to the highest point on a couch, usually on top of the pillows, and curl up into a ball. Chihuahuas have their own type of personality. They tend to be alert. Chihuahuas typically do not show fear; even though they are a smaller breed, they do not view their size as a disadvantage. 
Chihuahua puppies can be at risk for hypoglycemia (low blood sugar). Signs of hypoglycemia include lethargy, sleepiness, uncoordinated walking, unfocused eyes, spasms of the neck muscles or head pulling back or to the side, fainting, and seizures. Hypoglycemia can be avoided with adequate nutrition and frequent feedings, especially for Chihuahuas that are younger, smaller, or leaner. Chihuahua owners should have a simple-sugar supplement on hand to use in emergencies, such as Nutri-Cal or corn syrup. These supplements can be rubbed on the gums and roof of the mouth to rapidly raise the blood sugar level.
Beagles are used in a range of research procedures: fundamental biological research, applied human medicine, applied veterinary medicine, and protection of man, animals or the environment. Of the 8,018 dogs used in testing in the UK in 2004, 7,799 were beagles (97.3%). In the UK, the Animals (Scientific Procedures) Act 1986 gave special status to primates, equids, cats and dogs and in 2005 the Animal Procedures Committee (set up by the act) ruled that testing on mice was preferable, even though a greater number of individual animals were involved. In 2005 beagles were involved in less than 0.3% of the total experiments on animals in the UK, but of the 7670 experiments performed on dogs 7406 involved beagles (96.6%). Most dogs are bred specifically for this purpose, by companies such as Harlan. In the UK companies breeding animals for research must be licensed under the Animals (Scientific Procedures) Act.
Reality: It’s a fact that puppies are adorable! But the thing about puppies is, well, they grow up. And as they mature, their personality develops and that’s when you really find out whether your Pit Bull is dominant or submissive with people, or whether she is aggressive toward some, none or all dogs. Dog-intolerance and dog-aggression are traits that do not develop in some dogs until they are fully mature. It is possible that the cute little puppy you adopt who is friendly with all other dogs may not like other dogs at all later in life, even dogs she has grown up with and lived with for her entire life. Both nurture (environment) and nature (genetics) play a role in determining a dog’s mature personality. This doesn’t mean that Pit Bull puppies should not be adopted, but if you want to know how big your dog will ultimately be and how she will act around humans and other animals, you may want to consider adopting an adult.

The two coat varieties of the Chihuahua have slightly different grooming needs. The smooth-coat Chihuahua will need only occasional brushing and regular baths to look dapper, while the longhaired variety should have his coat brushed at least once a week to avoid any tangles or mats. Both varieties should have their nails trimmed regularly. Good dental care is necessary and should include brushing your dog’s teeth, and the vet might also recommend treats designed as part of a tooth-care program. Check the Chihuahua’s ears regularly, and remove any excess wax or debris to avoid ear infections.
Despite the many endearing qualities of the Chihuahua, if you’re thinking his tiny size makes him a great choice for children, you’d better think again. The Chihuahua may be just right for traveling around in a puppy purse, but he’s far too small and fragile for even the gentlest of children's games. Chihuahuas also tend to be high-strung and prone to nipping, snapping and even biting when frightened or threatened, or when defending his people or territory.
In the Smooth Coats, the coat should be of soft texture, close and glossy. (Heavier coats with undercoats permissible.) Coat placed well over body with ruff on neck preferred, and more scanty on head and ears. Hair on tail preferred furry. In Long Coats, the coat should be of a soft texture, either flat or slightly wavy, with undercoat preferred. Ears – Fringed. Tail – Full and long (as a plume). Feathering on feet and legs, pants on hind legs and large ruff on the neck desired and preferred. (The Chihuahua should be groomed only to create a neat appearance.) Disqualification – In Long Coats, too thin coat that resembles bareness.
The American Pit Bull Terrier has been known by many names, including the Pit Bull and the American Bull Terrier. It is often confused with the American Staffordshire Terrier, however, the United Kennel Club recognizes the American Pit Bull Terrier as its own distinct breed. Affectionately known as "Pitties," the Pit Bull is known for being a loyal, protective, and athletic canine breed.
Chihuahuas frequently have what's called a "molera," or an open fontanelle, which is a soft area under the skin of the forehead where the bony plates of the skull have not fused together. It may eventually close up and become hard, but in some dogs, the molera never fully closes. While many dogs can live a normal lifespan with a molera, some may have a condition called hydrocephalus (fluid buildup in and around the brain), which can cause seizures and even death if not treated. A Chihuahua with a molera can live a perfectly normal life, but he is more prone to head injuries so he’s not the best candidate for a home with rambunctious children or bigger, rougher dogs.
