These dogs are skillful, long living, and have a temperament which simply suits humans. They developed a solid red color later in their evolution before which, they were gray and brindle. They are also known for their courage and dominance, which is paired with a peaceful and eager-to-please attitude that they have towards the family members. Being a hyper breed, mental and physical exercises are essential. Overall, they are loyal, intelligent, and great as watchdogs.
As humans became more sophisticated, so did their dogs. Eventually, there emerged specific breeds of dogs, custom-bred to suit the breeders’ local needs and circumstances. The Greyhound, for instance, was the foundation type for the immense Irish Wolfhound and the dainty Italian Greyhound. All three have a distinct family resemblance, but you’d never mistake one for another.
Beagles are used as detection dogs in the Beagle Brigade of the United States Department of Agriculture. These dogs are used to detect food items in luggage being taken into the United States. After trialling several breeds, beagles were chosen because they are relatively small and unintimidating for people who are uncomfortable around dogs, easy to care for, intelligent and work well for rewards.[65] They are also used for this purpose in a number of other countries including by the Ministry of Agriculture and Forestry in New Zealand, the Australian Quarantine and Inspection Service, and in Canada, Japan and the People's Republic of China.[66] Larger breeds are generally used for detection of explosives as this often involves climbing over luggage and on large conveyor belts, work for which the smaller Beagle is not suited.[67]
I have a chiuhuahua border terrier cross. He’s just about 16 months old. It’s just me and my husband and he loves us equally. He hates kids, always barks and growls at them. He surprisingly likes most other people, unless my husband isn’t around, he gets protective over me if men come around me. He likes all dogs, big and small. He jumps at them and is very playful. He’s also very snugly and sweet. I have noticed the tranchea problem with him though and also his eyes water all the time. He’s fixed and still only weighs about 5 lbs. he’s been hard to potty train- he wouldn’t go out into the snow until this year. I usually have to carry him on walks in cold and wet weather because he’s always shivering. he’s inquisitive, likes to wander.. we have to keep a close eye on him at the dog parks because he can wiggle his way under the fence to run after the dogs! Definitely the best dog I ever had, he’s got the most unique personality, he’s not ‘yappy’ for the most part.. just at night when I’m trying to sleep lol.
"Yaya is a 5-year-old APBT my wife and I rescued from the Humane Society in Erie, PA. She is great with other dogs and especially a real lover when it comes to people. She is very loyal and loves to smother us with Pitbull kisses. Having gone through a tragic loss in the family a couple of years ago, she has been the best 'therapist' one could ask for. She can be stubborn sometimes; that trait she gets from my wife!"
In general, pit bulls aren’t aggressive with people but are “less tolerant” of other dogs than many other breeds, says Pamela Reid, PhD, vice president of the ASPCA’s Animal Behavior Center in New York. They also have “great tenacity. They put their mind to something, and they do it. That’s what makes them great dogs for sports like weight pulling. They are very strong, athletic animals," Reid says.

Prone to rheumatism, slipped stifle, colds and gum problems. Also corneal dryness and secondary glaucoma, due to their protruding eyes. Gains weight easily. Take caution around toxic products such as chocolate or fertilizer. This is a very small breed and it will not take much to poison them. Chihuahuas are often born via cesarean section because puppies are born with relatively large heads. Susceptible to fractures and other accidents in puppyhood. Some Chihuahuas have a molera, an unclosed section of the skull which can remain open throughout life. This makes the dog prone to injury. Has a tendency to wheeze and snore because of their small, short muzzles. Prone to stress, caused by the owners tendency to treat them like little babies. All dogs, even tiny ones, need to feel their owners are strong-minded beings able to handle the entire pack.
Remember that after you’ve taken a new puppy into your home, you have the power to protect him from two of the most common health problems: obesity (which makes other health issues worse) and eating inappropriate objects. Keeping a Beagle at an appropriate weight is one of the easiest ways to extend his life, and close supervision of what he’s chewing on can save you big bucks at the veterinary hospital. Make the most of your preventive abilities to help ensure a healthier dog for life.
I have a, what i am discovering a Ratcha…she is intelligent, housebroke at 3 months, and at first frightened by children. But my job and life evolve around children. Now she loves them. Some people she does not like, no matter how hard they try to warm up to her. But once she likes you, she really likes you. She has anxieties over several things. Before a long car ride I have to give her melatonin. Loud noise petrifies her. She loves to cuddle up in the warm blankets as soon as they come out of the dryer. She burrows underneath her blankets…the warmer the better. She chases the cats, but doesnt hurt them. She barks alot, but a bark collar helps. She chokes easy, so you have to put on a vest type collar when going for walks. She follows me to every room…no matter. If I put on a space heater, shes the first one there. The cats are no match with her in catching mice. She has it within seconds of its being in the open. Shes fast! She loves squeaky toys, but wants you to throw it, and fight her for it. Then she shakes it to death! Shes extremely loyal to me. Her name is Gidget, and I love this little dog with all my heart.
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.
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.
By the fourteenth century, hare-hunting had become a popular sport in England, and the dogs used were probably of Beagle type. The origin of the name Beagle may be from old French words meaning open throat in reference to the breed’s melodious bay, or from the Celtic, old English, or old French words for small. The word Beagle was not used until 1475, however, but can then be found frequently in writings from the sixteenth century on.
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. 
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.[70][71] Of the 8,018 dogs used in testing in the UK in 2004, 7,799 were beagles (97.3%).[72] 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.[73] 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%).[70] 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.[73]
Beagles like to do what they want to do, not necessarily what you want them to do. They are true masters when it comes to selective hearing. If a Beagle isn’t interested in the request you’ve made — commands are futile with this breed — he will simply ignore you or wander off. That can be frustrating if you’re not prepared for it. Successfully living with a Beagle means making everything a game, one that will hold his attention.
Beagles are used as detection dogs in the Beagle Brigade of the United States Department of Agriculture. These dogs are used to detect food items in luggage being taken into the United States. After trialling several breeds, beagles were chosen because they are relatively small and unintimidating for people who are uncomfortable around dogs, easy to care for, intelligent and work well for rewards.[65] They are also used for this purpose in a number of other countries including by the Ministry of Agriculture and Forestry in New Zealand, the Australian Quarantine and Inspection Service, and in Canada, Japan and the People's Republic of China.[66] Larger breeds are generally used for detection of explosives as this often involves climbing over luggage and on large conveyor belts, work for which the smaller Beagle is not suited.[67]
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.
Dogs of either coat type may be identified as either "apple head" or "deer head" Chihuahuas, particularly in the United States. Apple heads have rounded heads, close-set eyes, and relatively short ears and legs. Deer heads have flat-topped heads, more widely set eyes, larger ears, and longer, more slender legs. Deer heads were the breed standard conformation in the mid-20th century, but current breed standards defined by registries such as the AKC specify the apple-head conformation.[13]
Beagles are excellent with children and this is one of the reasons they have become popular family pets. But as beagles are pack animals, they are prone to separation anxiety,[44] a condition which causes them to destroy things when left unattended. Not all beagles will howl, but most will bark when confronted with strange situations, and some will bay (also referred to as "speaking", "giving tongue", or "opening") when they catch the scent of potential quarry.[45] They also generally get along well with cats and other dogs. They are not too demanding with regard to exercise; their inbred stamina means they do not easily tire when exercised, but they also do not need to be worked to exhaustion before they will rest. Regular exercise helps ward off the weight gain to which the breed is prone.[46]
Violent interactions between humans and canines have been studied by the U.S. government,[30] notably the Center for Disease Control and Prevention (CDC),[31] as well as academic veterinary researchers.[1] The interpretation of these studies, breed identification and relevance[32] issues, and variable circumstances have given rise to intense controversy.[33][34][35]

The Chihuahua is a good companion dog. Courageous, extremely lively, proud and adventurous, they enjoy affection. Brave, cheerful and agile, Chihuahuas can be strong-willed without proper human leadership. They are loyal and become attached to their owners. Some like to lick their owner's faces. Socialize them well. For some, they may be slightly difficult to train, but they are intelligent, learn quickly, and respond well to proper, firm but gentle (positive reinforcement) training. May be difficult to housebreak. Do not let the Chihuahua get away with things you would not allow a large dog to do (Small Dog Syndrome), such as jumping up on humans. While it may be cute for a 5-pound tiny dog to put his paws on your leg when you come home from work, it is allowing a dominant behavior. If you allow this little dog to be your pack leader it will develop many behavior issues such as jealousy, aggression with other dogs and sometimes with humans, and will become undeniably suspicious of people except for its owner. When strangers are present, it will begin to follow its owner's every move, keeping as close as possible. A Chihuahua that is pack leader of its humans may snap at children. This breed is generally not recommended for children, not because it is not good with them, but because most people treat the Chihuahua differently than they would a large dog, causing it to become untrustworthy. Because of its size, this breed tends to be babied and things we humans clearly see as bad behavior for a large dog are looked over as cute with a small dog. Small dogs also tend to be walked less, as humans assume they get enough exercise just running around during the day. However, a walk provides more than just exercise. It provides mental stimulation and satisfies the migration instinct all dogs have. Because of this, small breeds such as the Chihuahua tend to become snappish, yappy, protective and untrustworthy with kids and humans they do not know. Chihuahuas that are their human's pack leader tend to be fairly dog-aggressive. An owner who realizes this and treats the Chihuahua no differently than they would a large breed, becoming a clear pack leader, will get a different, more appealing temperament out of this wonderful little dog, finding it to be a good little child companion.

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.
The largest state in Mexico, Chihuahua is headquarters for the world’s fifth largest oil company, Pertróleos Mexicanos. It is also where one of the smallest canine breeds, the Chihuahua, originated. After railroad travel to the Copper Canyon area was upgraded following privatization of the railroad in 1998, tourism became an important and growing segment of the economy. Attractions include the beautiful Copper Canyon region and Pancho Villa’s mansion.
Careful breeders screen their breeding dogs for genetic disease and breed only the healthiest and best-looking specimens, but sometimes Mother Nature has other ideas and a puppy develops one of these diseases despite good breeding practices. Advances in veterinary medicine mean that in most cases the dogs can still live a good life. If you’re getting a puppy, ask the breeder about the ages of the dogs in her lines and what they died of.
Beagles are generally healthy, but certain health problems can affect them if breeders aren’t careful about performing health checks. They include hip dysplasia, a genetic malformation of the hip socket and certain types of heart conditions. Despite good breeding, Beagles may experience tears of the anterior cruciate ligament, which can require surgical repair, and intervertebral disc disease, a spinal problem that can make movement painful and may require surgical repair.

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.

The majority of Chihuahuas are healthy little dogs, but there are some genetic issues that can affect the breed. You should choose your dog from a breeder who routinely does genetic health screenings on all breeding stock to ensure that the puppies they produce are as genetically sound as possible. Some of the issues that can possibly affect the Chihuahua include potential heart problems (patent ductus arteriosus, mitral valve disease), eye disease, and patellar luxation (loose kneecaps). Idiopathic epilepsy is also known to occur in the breed.
How can you tell whether a Chihuahua puppy will mature at 4 lbs and up? There's a general rule of thumb that says you can take the weight of a Chihuahua puppy at 14 weeks old and double it to estimate his adult weight. So to get an adult who will weigh 4 lbs and up, look for a 14-week-old pup who weighs at least 2 lbs. It's not perfect, but it's usually pretty close.

Allergies: Allergies are quite common in APBT/AmStaffs. Skin allergies are typically caused by such environmental allergens as fleas, grass, pollen, and dust.They can also be food related, but this is less common. Common food allergens include beef, rice, wheat, and corn. Allergies can cause intense itching and discomfort, which means dogs will dig and chew sometimes till they bleed. This is risky because secondary infections can develop in the damaged tissue. To treat allergies, the cause must be identified and removed from the dog's environment if possible. A veterinarian can help you with this, as well as let you know which allergy symptoms can be controlled with medication.
Beagles bond with everyone in the family, especially children. They can be rambunctious when playing, however, so they need to be properly socialized and supervised with very young children. In addition, Beagles tend to be "mouthy," grabbing things, including your or your child's hand, with their mouths to play. They do this in fun and can be trained not to do this.
By the 18th century two breeds had been developed for hunting hare and rabbit: the Southern Hound and the North Country Beagle (or Northern Hound). The Southern Hound, a tall, heavy dog with a square head, and long, soft ears, was common from south of the River Trent and probably closely related to the Talbot Hound. Though slow, it had stamina and an excellent scenting ability. The North Country Beagle, possibly a cross between an offshoot of the Talbot stock and a Greyhound, was bred chiefly in Yorkshire and was common in the northern counties. It was smaller than the Southern Hound, less heavy-set and with a more pointed muzzle. It was faster than its southern counterpart but its scenting abilities were less well developed.[9] As fox hunting became increasingly popular, numbers of both types of hound diminished. The beagle-type dogs were crossed with larger breeds such as Stag Hounds to produce the modern Foxhound. The beagle-size varieties came close to extinction but some farmers in the South ensured the survival of the prototype breeds by maintaining small rabbit-hunting packs.
In the case of the Chihuahua, blue merle Dachshunds were probably crossed in. Which essentially means that merle Chihuahuas aren't truly purebred. But since genetic diversity is a good thing in living creatures, I don't view cross-breeding as an evil thing. If there are a few Dachshund genes floating around in a merle Chihuahua, that wouldn't bother me.
Likenesses of Chihuahua-like dogs decorate the artifacts of lost civilizations around the world. Trading among ancient cultures was more widespread than commonly assumed, so it is no surprise that similar dog types took root in far-flung places. How the Chihuahua type first came to the peoples of Mexico, however, is a secret of prehistory. We do know that when the Toltecs held sway in Mexico about a thousand years ago, their breed of choice was the Techichi, a larger, heavier ancestor of today’s Chi.
Two-color varieties always have a white base color with areas of the second color. Tan and white is the most common two-color variety, but there is a wide range of other colors including lemon, a very light tan; red, a reddish, almost orange, brown; and liver, a darker brown, and black. Liver is not common and is not permitted in some standards; it tends to occur with yellow eyes. Ticked or mottled varieties may be either white or black with different colored flecks (ticking), such as the blue-mottled or bluetick beagle, which has spots that appear to be a midnight-blue color, similar to the coloring of the Bluetick Coonhound. Some tricolor beagles also have ticking of various colors in their white areas.[33][34]
