Pit bull is the common name for a type of dog descended from bulldogs and terriers. The pit bull-type is particularly ambiguous, as it encompasses a range of pedigree breeds, informal types and appearances that cannot be reliably identified. Formal breeds often considered to be of the pit bull-type include the American Pit Bull Terrier, American Staffordshire Terrier, American Bully, and Staffordshire Bull Terrier. The American Bulldog is also sometimes included. Mixed-breed dogs which physically resemble these breeds often get labelled as "pit bulls" by shelters. Many of these breeds were originally developed as fighting dogs from crossbreeding bull-baiting dogs (used to hold the faces and heads of larger animals such as bulls) and terriers. After the use of dogs in blood sports was banned, such dogs were used as catch dogs in the United States for semi-wild cattle and hogs, to hunt and drive livestock, and as family companions. Despite dog fighting now being illegal in the United States, it still exists as an underground activity, and pit bulls are a common type used.
In Beagles, you should expect to see health clearances from the Orthopedic Foundation for Animals (OFA) for hip dysplasia (with a score of fair or better), elbow dysplasia, hypothyroidism, and von Willebrand's disease; from Auburn University for thrombopathia; and from the Canine Eye Registry Foundation (CERF) certifying that eyes are normal. You can confirm health clearances by checking the OFA web site (offa.org).
The Chihuahua, which has an average lifespan of 14 and 18 years, is known to suffer from some minor health ailments such as keratoconjunctivitis sicca (KCS), hypoglycemia, pulmonic stenosis, patellar luxation, and hydrocephalus. It is also susceptible to some severe health issues, including molera -- a hole in the Chihuahua's skull, occurring when bones in the fontanel are not firmly knit together.
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.
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.

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". 
Beagles were in the United States by the 1840s at the latest, but the first dogs were imported strictly for hunting and were of variable quality. Since Honeywood had only started breeding in the 1830s, it is unlikely these dogs were representative of the modern breed and the description of them as looking like straight-legged Dachshunds with weak heads has little resemblance to the standard. Serious attempts at establishing a quality bloodline began in the early 1870s when General Richard Rowett from Illinois imported some dogs from England and began breeding. Rowett's Beagles are believed to have formed the models for the first American standard, drawn up by Rowett, L. H. Twadell, and Norman Ellmore in 1887. The beagle was accepted as a breed by the American Kennel Club (AKC) in 1885. In the 20th century the breed has spread worldwide.
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.
Accustom your American Pit Bull Terrier to being brushed and examined when he's a puppy. Handle his paws frequently — dogs are touchy about their feet — and look inside his mouth and ears. Make grooming a positive experience filled with praise and rewards, and you'll lay the groundwork for easy veterinary exams and other handling when he's an adult.
Thank you for the amazing article, filled with great and interesting information! I love such a clear-minded and healthy approach, where one can simply see that people truly know what they're talking about. Too often, as in negative myths, people write "oh they're just wonderful". Which is true!, but, it is better to be educated and have strong facts behind the statement so one can have a trustful argument when speaking – and to really show the people what is TRUE, not a personal opinion – be it in a positive or negative context.
"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)
