The Beagle has an average lifespan of 12 to 15 years. While this breed is generally healthy overall, some specific ailments that are known to affect the Beagle breed are patellar luxation, glaucoma, epilepsy, central progressive retinal atrophy (CPRA), hypothyroidism, distichiasis, chondrodysplasia, cherry eye, and keratoconjunctivitis sicca (KCS). Deafness, cataract, hemophilia A, demodicosis, and umbilical hernia are some other health problems that affect the breed, while some major ailments include primary carnitine deficiency (CUD) and intervertebral disk disease. Some exams used to identify these conditions include hip, thyroid, and eye tests.
Chihuahuas possess loyalty, charm, and big-dog attitude. Even tiny dogs require training, and without it this clever scamp will rule your household like a little Napoleon. Compact and confident, Chihuahuas are ideal city pets. They are too small for roughhousing with kids, and special care must be taken in cold weather, but Chihuahuas are adaptable—as long as they get lots of quality time in their preferred lap.
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.
There is no pit bull type or breed. It is that mislabeling that jas caused BSL and the issues in today's society. Pit bull is short for American pit bull terrier. Nothing else is a pit bull. They are other breeds bred for other purposes. Most today are BBM bull breed mixes. APBT are very athletic high energy dogs and are dog aggressive but not human aggressive. Many of these other dogs are the ones who are human aggressive and give pit bulls a bad name because of mislabeling. I have worked with APBT nad other bull breeds around 25 yrs and bred heritage apbt for 20.
Stop them from jumping. Never allow your Maltese Terrier, or any dog for that matter, to jump on guests. Your dog can’t distinguish between dog persons and those afraid of canines. It also can’t tell if the guest is a young friend or an 80-year-old relative with a hip problem. Ask your guest to turn away from your Morkie and ignore it until it sits quietly. Only then can you pay it attention.
In several entries you will see that the dog was originally bred for fighting. In noting this, we are simply highlighting the motive for its creation. In no case does this determine the behavior of an individual Pit Bull and under no circumstances does it mean every dog is intended solely for this purpose. All dogs deserve a home with caring and responsible owners willing to meet all their needs. Obviously, clandestine dog fighting is an intolerable practice.
Thank you so much for this comment. Professionalism and warmth is part of what we aim for, so we appreciate when it gets recognized. Some contentious topics lead to understandable emotional responses, on both sides. We don't want to offend anyone's views, but our approach will be an unapologetically evidence-based one. Thanks again for your support.
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.
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.
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).
In a 2014 literature review of dog bite studies, the American Veterinary Medical Association (AVMA) states that breed is a poor sole predictor of dog bites. Controlled studies have not identified pit bulls as disproportionately dangerous. Pit bull-type dogs are more frequently identified with cases involving very severe injuries or fatalities than other breeds, but the review suggests this may relate to the popularity of the breed, noting that sled dogs, such as Siberian Huskies, were involved in a majority of fatal dog attacks in some areas of Canada. Bite statistics by breed are not tracked by the CDC, AVMA or the American Society for the Prevention of Cruelty to Animals (ASPCA). State Farm Insurance spokeswoman Heather Paul stated "Pit bulls in particular are often misidentified when a bite incident occurs, so reliable bite statistics related to the dogs’ breed are unreliable and serve no purpose." The White House stated that "the Centers for Disease Control and Prevention looked at twenty years of data about dog bites and human fatalities in the United States. They found that fatal attacks represent a very small proportion of dog bite injuries to people and that it’s virtually impossible to calculate bite rates for specific breeds". 
There are reports of small pack-hounds employed to hunt rabbit and hare in England long before the Roman legions arrived in 55 B.C. An English authority called the Beagle the “foothound of our country, indigenous to the soil.” By the 1500s, most English gentlemen had packs of large hounds that tracked deer, and smaller hounds that tracked hares. The smaller, more compact hounds were ancestors of our modern Beagle.
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.
