Glaucoma: This is a painful disease in which pressure in the eye becomes abnormally high. Eyes are constantly producing and draining a fluid called aqueous humor — if the fluid doesn't drain correctly, the pressure inside the eye increases causing damage to the optic nerve and resulting in vision loss and blindness. There are two types. Primary glaucoma, which is hereditary, and secondary glaucoma which is a result of inflammation, a tumor, or injury. Glaucoma generally affects one eye first, which will be red, teary, squinty, and appear painful. A dilated pupil won't react to light, and the front of the eye will have a whitish, almost blue cloudiness. Vision loss and eventually blindness will result, sometimes even with treatment (surgery or medication, depending on the case).

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.

Hunters could follow these dogs on foot and could even carry one in a pocket if the need arose. By the 1800s, Beagles existed in several sizes, but the smaller “pocket-size” dogs were particularly popular. These dogs measured only about 9 inches and often needed the hunter’s assistance in crossing rough fields. One of the special appeals of the smaller Beagles was that the hunt could be followed even by “ladies, the aged, or the infirm,” as they slowly followed the winding path of the hare.
If you live in a cold or rainy climate, housebreaking will be especially difficult, because Chihuahuas hate both the cold and the rain. In these climates, a COVERED potty area is strongly recommended. Sometimes a doggy door is necessary so your Chihuahua can run outside the moment he feels the urge in his tiny bladder. An indoor litterbox is another option.
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.

The longcoated Chihuahua is the product of a recessive gene, meaning a puppy must have the gene from both parents for the long coat to express itself, so he isn’t seen in litters as frequently as the smooth. The long, soft coat is flat or slightly curly, and the dog has a ruff around the neck, fringed ears, feathering on the legs and a plumed tail. The hair on the rest of the body is almost as smooth as that on the smooth Chihuahua. Longcoated Chihuahuas are beautiful, and they’re easy to groom, but they do shed seasonally.
We own a 10 lb chi/terrier mix who has some serious itchy under belly hair loss going on. She has tested negative for allergies and has been on hydrolyzed food now for a month with no changes to her hair loss. She also takes appoquel daily. Along with this, she will randomly pee in the house. She seems like a very bright dog, so this trait is very frustrating. Not sure what the next step will be but would appreciate hearing from others in this situation.
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.
There are two Beagle varieties: those standing under 13 inches at the shoulder, and those between 13 and 15 inches. Both varieties are sturdy, solid, and “big for their inches,” as dog folks say. They come in such pleasing colors as lemon, red and white, and tricolor. The Beagle’s fortune is in his adorable face, with its big brown or hazel eyes set off by long, houndy ears set low on a broad head.
Any dog, no matter how nice, can develop obnoxious levels of barking, digging, food stealing and other undesirable behaviors if he is bored, untrained or unsupervised. And any dog can be a trial to live with during adolescence. In the case of the Beagle, the “teen” years can start at six months and continue until the dog is about three years old and sometimes throughout life. Some Beagles just never lose that fun-loving, happy-go-lucky puppy nature. While it makes them entertaining to live with, it also means that they need more supervision than the average adult dog. Fair warning!
Reality: Pit Bulls do not have any special physical mechanism or enzyme that allows them to “lock” their jaws. If you compare a Pit Bull skull to a skull of any other dog breed, you can see with the naked eye that both skulls share the same characteristics and general bone structure. However, one personality trait of the Pit Bull breed is determination. Whatever Pit Bulls do, they do it with a great deal of enthusiasm, and it is this trait that can make it seem like they have a locking jaw when they bite down on something and are determined not to release it.
Developed from the Bull and Terrier types dogs, the American Pit Bull Terrier can be traced back to the early 1800s in what is now known as the United Kingdom. They were bred as an all-around farm dog, working the farms as a cattle/hog dog. Some chose to turn their talents into the sport of pit-fighting. The breed's tenacity and accompanying strength are unmatched in the canine world. As rich and captivating as the breed's history is, the Pit Bull's future is more worthy of commentary. Some proponents of the breed argue that this breed is the original bulldog of the past. Old prints and woodcarvings show reason to believe this. They show dogs that look exactly like the breed today, doing things the dog is still capable of doing. For more information on this theory you can read books by Richard F. Stratton. The APBT, as registered by the UKC, is an individual breed of dog and does not refer to just any ill-bred, mindless warrior-type mongrel. At one time, the Pit Bull had an all around reputation of a much loved, trustworthy companion. Unfortunately the breed has become a status symbol for many types of criminals who chose to train these dogs to fight. It is those types of people who are chiefly responsible for the banning and witch-hunting that has been sweeping the U.S. The media, however, should not go unmentioned, for it is also responsible for escalating isolated incidences in a relentless and attention-getting way. Most Pit Bulls are bred as family dogs or sports such as weight pulling, but the media will rarely mention this. They get more views pretending all Pit Bulls are bred by fighters. In a lot of cases when the media is reporting about a Pit Bull attacking, it is indeed not even a Pit Bull at all, but a mixed breed of some sort, or another bull breed all together. For example, there was a report on KYW news in Philadelphia about two Pit Bulls attacking a person. The dogs did not look like Pit Bulls, but rather Boxer mixes. The news station was called and asked if they knew the dogs were in fact purebred American Pit Bull Terriers, or another bull breed of some sort, or mutts, for that matter. They stated they did not know, and to call the police station to verify that information. They were asked how they could report something that they were not sure of. They had no answer and they were not sure of the dogs’ breeds. Even after admitting on the phone that they did not in fact know the breeds of the dogs in question, they kept calling the dogs Pit Bulls in their reports. Why? Because the name Pit Bull will draw out the most attention from the public. The Pit Bull's future has been perhaps irreparably undone and everyone is to blame except the dog itself. This very loyal dog is too set on pleasing his owner, and ironically this is the root of his own undoing. Accompanying this need to please are remarkable abilities of all kinds. Jack Dempsy, Teddy Roosevelt and Jack Johnson are just a few people who have owned Pit Bulls. Pit Bulls excel in practically every canine task including herding, guarding, hunting, policing, cart pulling and ratting. A Pit Bull named Banddog Dread holds more canine working titles than ANY other breed. The owner's name is Diane Jessup and you can reference her book "The Working Pit Bull." It tells all of Dread's accomplishments. These dogs are truly capable of many tasks. The difference between Pits and American Staffordshire Terriers is a difficult one. Even breeders can't agree. The main difference is the bloodline. Amstaffs are show dogs and dog fighters usually do not use dogs with Amstaff blood. As time progresses there will be more of a difference. Many are dual registered as Amstaffs with the AKC and Pits with the UKC.
Your Beagle’s personality will also be affected by the kind of breeder who produced him. Beagles from breeders who produce hunting dogs are more likely to be hard-charging and demanding of exercise. They are unsuited to lying around the house all day while everyone is at work or school. More laid back Beagles typically come from a breeder who shows dogs in conformation.
Now, the actual amount of shedding depends on whether the coat is single or double. NOT on whether the coat is short or long, but whether it is double (outer coat plus undercoat) or single (just an outercoat). Remember we talked about single and double coats earlier. Whether a coat is short or long, the double coats shed more than the single coats. Which makes sense.
Alongside the Bloodhound and Basset Hound, the beagle has one of the best developed senses of smell of any dog.[35] 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.[35] The long ears and large lips of the beagle probably assist in trapping the scents close to the nose.[36]
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 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.
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.

Beagles are used as sniffer dogs for termite detection in Australia,[81] and have been mentioned as possible candidates for drug and explosive detection.[82][83] Because of their gentle nature and unimposing build, they are also frequently used in pet therapy, visiting the sick and elderly in hospital.[84] In June 2006, a trained Beagle assistance dog was credited with saving the life of its owner after using her owner's mobile phone to dial an emergency number.[85] In the aftermath of the 2010 Haiti earthquake, a Beagle search and rescue dog with a Colombian rescue squad was credited with locating the owner of the Hôtel Montana, who was subsequently rescued after spending 100 hours buried in the rubble.[86] Beagles were hired by New York City to help with bedbug detection,[87] while the role of such dogs in this type of detection may have doubts.[88]
The word “beagle” is thought to have come from certain old French words meaning an open throat, a possible connection to the dog’s musical bay. It is also speculated that the dog’s name might have derived from old French, Celtic or English words meaning small. Beagle-like dogs were probably used for the popular sport of hare-hunting in England during the 1300s, but the term "beagle" was not used until 1475. Hunters would follow the dog on foot and sometimes even carry one in his pocket. There were several sizes of Beagles in the 1800s, but the pocket-size dogs were most popular. These small dogs measured only about nine inches and required the hunter's help while crossing rough fields. Because the smaller Beagles were slower and easier to follow on foot, they appealed especially to women, the elderly, and those who otherwise did not have the stamina or inclination to keep up with an active dog.
I have just taken on an 11 year old foxy/chihuahua cross and her same age poodle/Maltese boy. The foxy cross only weighs about 3.5 kg. She is a delightful dog. Well house trained and a good inquisitive walker. After two weeks she is very protective of us. She seems fine with other adults and children. Though we don’t have any. She loves chasing balls and we spend time doing that with her as otherwise she has too much energy. She is very very smart. She likes to follow you everywhere and lies next to you once she has been exercised. She was an escape artist but I have had the door open inadvertently and she seemed to have been happy to stay. I adore both these dogs already.
Apple head Chihuahuas can have moleras, or a soft spot in their skulls, and they are the only breed of dog to be born with an incomplete skull. This is not a defect; it is a normal adaptation facilitating the passage through the birth canal and growth and development of the domed type of forehead. The molera is predominant in the apple heads and is present in nearly all Chihuahua puppies. The molera fills in with age, but great care needs to be taken during the first six months until the skull is fully formed. Some moleras do not close completely and require extra care to prevent injury.[38]
Chihuahuas occur in virtually any color combination, from solid to marked or splashed,[19] allowing for colors from solid black to solid white, spotted, sabled, or a variety of other colors and patterns. Colors and patterns can combine and affect each other, resulting in a very high degree of variation. Common colors are fawn, red, cream, chocolate, brown, mixed, white, and black. No color or pattern is considered more valuable than another.

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.


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.

Following the revolution, Chihuahua remained a hub of Institutional Revolutionary Party (PRI) influence. Because of its proximity to the United States, Chihuahua was strategically important to Mexico. The region was also central to the oldest and most important opposition party during PRI rule, the National Action Party (PAN). State leader Luis H. Álvarez became the PAN presidential candidate in 1958 after an unsuccessful run for governor. In 1992, Chihuahua became one of the first states in Mexico to elect a governor who was not a member of the PRI.
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.[6] 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:
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.

Tiny dogs often come with big health problems, and the Chihuahua is no exception. Many Chihuahuas live long, healthy lives, but conditions seen in the breed include breathing difficulties caused by a windpipe that collapses in on itself; luxating patellas; eye disorders; congestive heart disease; certain neurological conditions including hydrocephalus (fluid buildup in and around the brain), neuronal ceroid lipofuscinosis, a condition in which fatty pigments in the brain cause the progressive loss of brain function, and atlantoaxial subluxation, a neck deformity that may require surgical correction; obesity; and dental problems caused by the small size of their mouths.

And before you decide to buy a puppy, consider whether an adult Chihuahua 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 Chihuahua 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.
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.[27] 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. [28]
Avoid breeders who only seem interested in how quickly they can unload a puppy on you and whether your credit card will go through. You should also bear in mind that buying a puppy from websites that offer to ship your dog to you immediately can be a risky venture, as it leaves you no recourse if what you get isn’t exactly what you expected. Put at least as much effort into researching your puppy as you would into choosing a new car or expensive appliance. It will save you money in the long run. For more information about the breed or to find a list of breeders, visit the website of the National Beagle Club.

In the United States they appear to have been employed chiefly for hunting rabbits from the earliest imports. Hunting hare with beagles became popular again in Britain in the mid-19th century and continued until it was made illegal in Scotland by the Protection of Wild Mammals (Scotland) Act 2002 and in England and Wales by the Hunting Act 2004. Under this legislation beagles may still pursue rabbits with the landowner's permission. Drag hunting is popular where hunting is no longer permitted or for those owners who do not wish to participate in hunting a live animal, but still wish to exercise their dog's innate skills.

My rescue is Iggyboo, a cairn terrier/Chihuahua mix, weighing in at 10 lbs and only 8 inches tall, now at almost 3 yrs. He is very protective and loyal, and pretty much a lap dog. He loves to play with his toys, and is highly intelligent, often preferring his interactive toys over stuffed ones. I find myself constantly teaching him new words or playing new games. He hates children and often adults, but can warm up to people given a few minutes and a few kind words (treats help this process). He also can be a challenge to walk, being aggressive to other dogs, but responds very well to a clicker and a treat for distraction. So, generally I have had no issues with him on walks, but am always careful. He loves bedtime, and burrows under the covers, sleeping a full 8 hours straight, he gets upset if I roll over and wake him up and will growl at me, lol.
The Beagle should do well on a high-quality dog food, whether commercially manufactured or home-prepared with your veterinarian’s supervision and approval. Any diet should be appropriate to the dog’s age (puppy, adult, or senior). Some dogs are prone to getting overweight, so watch your dog’s calorie consumption and weight level. Treats can be an important aid in training, but giving too many can cause obesity. Learn about which human foods are safe for dogs, and which are not. Check with your vet if you have any concerns about your dog’s weight or diet. Clean, fresh water should be available at all times.
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.
It is really common. They are Chi’s at heart sometimes and they are bred as lap/companion dogs so they are naturally very protective of their owners. Especially to Larger dogs and humans. What I have found with my baby girl is that she has what I call “big dog syndrome.’ As in she thinks she is much bigger than she is. She’ll get up in another dogs face in a heartbeat if it meant telling them to stay away from me. Once I pet that dog and talk to her when I do it she calms down and after 5-10 minutes she is best friends with them. Humans too. lol. It is just their way of being there for you too. Even if it is unwanted. Best thing is to roll with it and show them its alright and eventually they learn. they are so smart.

English and American varieties are sometimes mentioned. However, there is no official recognition from any Kennel Club for this distinction. Beagles fitting the American Kennel Club standard – which disallows animals over 15 inches (38 cm) – are smaller on average than those fitting the Kennel Club standard which allows heights up to 16 inches (41 cm).
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.
"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)
The American Kennel Club recognizes two separate varieties of beagle: the 13-inch for hounds less than 13 inches (33 cm), and the 15-inch for those between 13 and 15 inches (33 and 38 cm). The Canadian Kennel Club recognizes a single type, with a height not exceeding 15 inches (38 cm). The Kennel Club (UK) and FCI affiliated clubs recognize a single type, with a height of between 13 and 16 inches (33 and 41 cm).
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.
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.
Chihuahuas can be easily frightened or provoked to attack, so are generally unsuitable for homes with small children.[25] The breed tends to be fiercely loyal to one particular person and in some cases may become overprotective of the person, especially around other people or animals,[25] and tend to have a "clannish" nature, often preferring the companionship of other Chihuahuas or Chihuahua mixes over other dogs.[26] These traits generally make them unsuitable for households with children who are not patient and calm.[19]
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.
