From medieval times, beagle was used as a generic description for the smaller hounds, though these dogs differed considerably from the modern breed. Miniature breeds of beagle-type dogs were known from the times of Edward II and Henry VII, who both had packs of Glove Beagles, so named since they were small enough to fit on a glove, and Queen Elizabeth I kept a breed known as a Pocket Beagle, which stood 8 to 9 inches (20 to 23 cm) at the shoulder. Small enough to fit in a "pocket" or saddlebag, they rode along on the hunt. The larger hounds would run the prey to ground, then the hunters would release the small dogs to continue the chase through underbrush. Elizabeth I referred to the dogs as her singing beagles and often entertained guests at her royal table by letting her Pocket Beagles cavort amid their plates and cups. 19th-century sources refer to these breeds interchangeably and it is possible that the two names refer to the same small variety. In George Jesse's Researches into the History of the British Dog from 1866, the early 17th-century poet and writer Gervase Markham is quoted referring to the beagle as small enough to sit on a man's hand and to the:
Dogs termed pit bulls share similar physical characteristics, but the morphological variation among bully breed dogs makes it difficult for even experts to visually identify them as distinct. While mixed-breed dogs are often labeled as pit bulls if they have certain physical characteristics, such as a square-shaped head or bulky body type, visual identification of mixed-breed dogs is not recommended by the scholarly community. Some of the breeds which often get mistaken for pit bulls (but which are not genetically pit bulls) include the Cane Corso, Dogo Argentino, Dogue de Bordeaux, and others, but because these breeds did not originate with the crossbreeding of bulldogs and terriers, they do not fall under the term "pit bull".
Small, compact, and hardy, Beagles are active companions for kids and adults alike. Canines in this dog breed are merry and fun loving, but being hounds, they can also be stubborn and require patient, creative training techniques. Their noses guide them through life, and they’re never happier than when following an interesting scent. The Beagle originally was bred as a scenthound to track small game, mostly rabbits and hare. He is still used for this purpose in many countries, including the United States.
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. 
The terrier mix dogs that we see and know today have a long breeding history. During the early 18th century, the terriers were crossed with hunting (explains their great sense of smell) or fighting (explains their guarding nature) dogs. This was done to improve their ability to hunt (either on land or in waters) or fight. By the 19th century, dog shows began to be organized, which resulted in careful and purposeful breeding. Since then, breeders started to breed dogs mainly as pets.
Alongside the Bloodhound and Basset Hound, the beagle has one of the best developed senses of smell of any dog. In the 1950s, John Paul Scott and John Fuller began a 13-year study of canine behavior. As part of this research, they tested the scenting abilities of various breeds by putting a mouse in a one-acre field and timing how long it took the dogs to find it. The beagles found it in less than a minute, while Fox Terriers took 15 minutes and Scottish Terriers failed to find it at all. Beagles are better at ground-scenting (following a trail on the ground) than they are at air-scenting, and for this reason they have been excluded from most mountain rescue teams in favor of collies, which use sight in addition to air-scenting and are more biddable. The long ears and large lips of the beagle probably assist in trapping the scents close to the nose.
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 is possible. He or she is more interested in placing pups in the right homes than in 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.
Beagles have what fans call a “musical” voice, but to your neighbors it’s just going to sound like really annoying noise. Beagles will sing along to sirens, “give tongue” when they are hunting, and bark when strangers come to the door, but they aren’t usually nuisance barkers unless they are bored or lonely. If you don’t live out in the country where no one else is around to hear his drawn-out “Aaaaarrrroooooh,” keep your Beagle occupied with toys, the company of another animal or, best of all, your presence so he doesn’t feel the need to serenade the neighborhood.
Chihuahuas are intelligent, graceful, and sometimes too brave for their own good. They usually bond with only one person and become highly devoted, frequently kissing the owner's face (with or without approval). The Chihuahua is reserved around strangers, and may attempt to defend their owner, usually with little effect. Chihuahuas are tenacious, proud, and very energetic.
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.
In addition to organized beagling, beagles have been used for hunting or flushing to guns (often in pairs) a wide range of game including snowshoe hare, cottontail rabbits, game birds, roe deer, red deer, bobcat, coyote, wild boar and foxes, and have even been recorded as being used to hunt stoat. In most of these cases, the beagle is employed as a gun dog, flushing game for hunter's guns.
Unfortunately, a lot of misinformation is posted online by anti-Pit Bull acolytes. Many provide information which ostensibly looks credible, but crumbles under scrutiny with only a little digging. One of the major pieces of ‘research’ is the so-called Clifton Report which is written by an author who defrauded readers in terms of his credentials and continually refuses to publish the raw data behind his claims.
Sites like Petfinder.com and Adopt-a-Pet.com can have you searching for a Chihuahua in your area in no time flat. The site allows you to be very specific in your requests (housetraining status, for example) or very general (all the Chihuahuas available on Petfinder across the country). AnimalShelter.org can help you find animal rescue groups in your area. Also some local newspapers have “pets looking for homes” sections you can review.
The Pit Bull immediately strikes one as being a dog of power, passion and undying willingness. The brick-like head, which is especially broad between the cheeks (to house the powerful jaws), is carried upon a thickly muscled, well-defined neck. The neck runs into a deep, thick, well-sprung chest. The American Pit Bull is a very muscular, stocky, yet agile dog that is extremely strong for his size.The tail tapers to a point. The ears are generally cropped, though this is optional. Docked tails are not accepted by the UKC or the ADBA. The eyes are round. Both the ADBA and the UKC do not accept blue eyes or the coat color merle. The American Pitbull Registry does accept a merle coat. The teeth should form a scissors bite. Its coat is made up of thick, short, shiny hair. All colors are admissible. Shades of brown to red with a matching red/brown nose are referred to as red-nose Pit Bulls. Shades of gray with a matching gray nose are referred to as blue-nose Pit Bulls.
Generally there is a wide interpretation of what is called “breed”. Breeds are actually categorized by a functional type from which a breed has developed. The most of the breeds are traditional breeds with a very long history, who are registered. There are some rare breeds, who have also their own registries, but some new breeds are still under development. There are even a lot of dog breeds, who are in danger to extinct. There are a few cases, where the origin of breed overlaps the frontier of two, three or more countries. As the general rule the dog is listed in the country in that he is most commonly associated, according to the FCI (Fédération Cynologique Internationale), by the designated country of the dog. There are some dogs, who have an uncertain origin, therefore they are getting classified under several countries.
