Their long floppy ears can mean that the inner ear does not receive a substantial air flow or that moist air becomes trapped, and this can lead to ear infections. Beagles may also be affected by a range of eye problems; two common ophthalmic conditions in beagles are glaucoma and corneal dystrophy. "Cherry eye", a prolapse of the gland of the third eyelid, and distichiasis, a condition in which eyelashes grow into the eye causing irritation, sometimes exist; both these conditions can be corrected with surgery. They can suffer from several types of retinal atrophy. Failure of the nasolacrimal drainage system can cause dry eye or leakage of tears onto the face.
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.
The Beagle originated in England. His heritage stretches back to the packs of hunting hounds kept by landed gentry to hunt deer and hare. Beagle-like scenthounds were known as far back as 1475, when the word “Beagle” was first used to describe this type of hunting dog. It’s a matter of debate whether the name comes from a Celtic word meaning “small” or a French word meaning “open mouth” or “loud mouth.” Given the Beagle’s propensity for baying when he catches an interesting scent on the wind, the latter theory seems most likely.
my comment is for all pit owners as being 1 myself ppl say its all in how ya raise them and i do believe thats true to some extent althjo if ya will recall new articals to where pit bulls have attacked every age from toddlers to old folks and everytime its all the same answer or comment my dog has never offered to bite any one he has never been aggressive a dog has a personality just like humans altho it seems like when a pit bull goes off the deep end there is no bringing them back i no that a pit is not the breed of dog that ranks up to the top or near the top for bites when a pit goes to bite he is very aggressive and will not stop untill its prey is dead thats why it has took me so long to get this breed trust is an issue to make a long story short i told my grand kids if she ever bites with aggression i will have her taken away from here n we shall h=get another beagle ( just saying )
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.
One of the most amiable hounds, the Beagle was originally bred to be part of a pack and needs companionship, whether human or canine. This dog loves to explore the outdoors and is an enthusiastic trailer. Given adequate exercise, the Beagle is a calm, tractable house pet. Beagles tend to be excellent with children, gentle, incredibly tolerant, and always ready to join in a game or adventure. This is an independent breed, however, and may run off if a trail beckons. Beagles bark and howl.
And before you decide to buy a puppy, consider whether an adult Beagle might better suit your needs and lifestyle. Puppies are loads of fun, but they require a lot of time and effort before they grow up to become the dog of your dreams. An adult Beagle may already have some training and will probably be less active, destructive and demanding than a puppy. With an adult, you know more about what you’re getting in terms of personality and health and you can find adults through breeders or shelters. If you are interested in acquiring an older dog through breeders, ask them about purchasing a retired show dog or if they know of an adult dog who needs a new home. If you want to adopt a dog, read the advice below on how to do that.
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:
"These are our Chi babies, from left: Maxwell (6 months), Milo (9 months) and Matilda (also 9 months). While Milo and Matilda are on the bigger side of the Chi scale at 7 and 9 lbs., Maxwell is on the more average size at about 4½ lbs. Milo is a bit more on the lazy side compared to the other two and sometimes will just sit and watch the others play. He is also a bit insecure which we are working on with him. They are all very loving however and are always anxious to share kisses with their humans and with each other alike. Sometimes they'll lie in the sun bathing each other’s faces and making sure they are all looking their best. Then they will burrow in blankets, pillows, etc. until they fluff it up just enough to get comfortable and then proceed to take a long nap. While none of them are the "alpha" (that's the humans job, isn't it?!) our female, Matilda is by far the most bossy out of the group. If she wants to play, you'd better play or else you'll get a "donkey kick" until she gets a reaction. Typical female! (and yes, I can say that because I AM a female! :o)
NOTE: How much your adult dog eats depends on his size, age, build, metabolism, and activity level. Dogs are individuals, just like people, and they don't all need the same amount of food. It almost goes without saying that a highly active dog will need more than a couch potato dog. The quality of dog food you buy also makes a difference — the better the dog food, the further it will go toward nourishing your dog and the less of it you'll need to shake into your dog's bowl.
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. 
This test is not perfect, but it does go some way to show the importance of treating the dog as an individual. This is the stance of the American Society for the Prevention of Cruelty to Animals which states that ‘genetics do not exist in a vacuum’. Many factors influence a dog's behavior, but this is true of all breeds. More important than breed is adequate socialization, humane treatment and early positive experiences in terms of a dog's aggression. By enforcing breed specific legislation, as pointed out by the ASPCA, you only create the illusion of public safety. By treating dogs on an individual basis you will be better able to stop attacks, prevent purposeful mistreatment and educate owners and the public about how to treat a animals safely and humanely.
The history of the Chihuahua is quite controversial. According to one theory, it was originally developed in China and then brought to the Americas by Spanish traders, where it was interbred with small native dogs. Others speculate it is of South and Central American origin, descended from a small, mute dog -- the native Techichi -- which was occasionally sacrificed in Toltec religious rites. It was believed that this diminutive red dog guided the soul to the underworld after death. Thus, all Aztec families kept this dog and buried it with the deceased member of the family. (Curiously, the Toltecs and the Aztecs also fed on the Techichi.) When not used in burial rituals, however, the Aztec and Toltec priests and families took great care of the Techichis.
All dogs have the potential to develop genetic health problems, just as all people have the potential to inherit a particular disease. Run, don’t walk, from any breeder who does not offer a health guarantee on puppies, who tells you that the breed is 100 percent healthy and has no known problems, or who tells you that her puppies are isolated from the main part of the household for health reasons. A reputable breeder will be honest and open about health problems in the breed and the incidence with which they occur in her lines. Here’s a brief rundown on what you should know.
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.
There are subcategories as working dogs, companion dogs, herding dogs, guard dogs, hunting dogs and sled dogs. Working dogs are for example lapdogs, who are used as therapy dogs. Companion dogs are just providing companionship and are known as pets and who are usually not used for specific tasks. Herding dogs are known as stock dog and they are working with livestock. They are also called pastoral dogs, who do not necessarily have to be trained in herding. Guard dogs defend the property of people. They are also named watch dogs or attack dogs. They bark aloud, when there is a presence of a possible intruder and alert in this way their owners. Hunting dog hunts with or for their owners. There are a lot of different types of dogs, who have the special hunting skills. Sled dogs are also named sledge dogs or sleigh dogs, who were bred historically for pulling sleds to transport or haul supplies into areas which are inaccessible by another method.
