I am an old man and have mainly been interested in one breed of dog for the most of my life. This is a history of that dog as I was taught. I am not sure of many of the facts and many will not agree but is only one of the many school of thought. The dog is not a true descendant of the wolf but a species more closely related to the fox which developed in parallel with the wolf. The wolf is still in existence in its true form and has not changed greatly during the life of man. The dog has greatly changed and has been developed into many different breeds. The wolf still hasn't been domesticated but the dog has. When man began to use the dog as more than a food source over the years they developed three types of dogs. The sight hound, the scent hound, and the kill dog. All three types are still found with only a little refinements over the many hundred of generations of breeding. The sight hound, the modern day greyhound, is really little changed from the dogs used even before the time of written records. There are many variations of this type dog which man has developed over the years to satisify the requirements of man. Some large, some small, some short hair, and some long hair. Basically the same dog. The scent hound, the modern day hunting dog, has underwent the most change of the three types. They come in many shapes and sizes. They are basically the same dog with the normal variations man has developed to better suit the dog to his type of hunting. Some specialize in hunting birds, some mammals, anything is possible. The kill dog, the modern day pit bull still registered by the A.D.B.A., is very nearly the same dog as was used before written records. The body style and size is very close to the same. They have been known by many names but by most of the old timers it is still known as a bulldog. From these three types of dogs there have been many different breeds developed. Most do the same type of job as the original dogs but have been refined to look more in style with what man wanted at that time. Since my interest has been the bulldog my studies and research has mainly been with these dogs. The original bulldog was split into three groups which included the smaller dogs, nowdays called the terriers, used for small animals and rodents, the mid size dog, nowdays called the pit bull, used for large animals, and the large size dog, nowdays called the mastiff, used for mainly intimadation and war dogs. In each group man has developed breeds of dogs that specialize in certain jobs. The mid size group of dogs, the pit bull, has remained basically the same dog. Man has developed many different breeds from the original. The english bulldog, bull terrier, american bulldog are more modern dogs bred from the original dog for different purposes, some just for the look that man thought would improve the original. The bulldog/terrier cross many think developed into the pit bull actually produced the modern day bull terrier which is a smaller dog originally developed for smaller game, mainly used in later days as a ratter. It was cheaper to keep and maintain than the larger dog and used for the smaller game that many families subsisted on. The modern day english bulldog was developed by man to be an improvement of the original dog that failed miserably. The shorter legs, wider chest, and undershot jaw was mans idea on what a dog should possess to hold and throw the larger animals and was intended mainly for bull baiting. It was later found to be a failure and the caused of the failures exaggrated to become more a large lap dog. The american bulldog is a later day breed which included a cross of the original bulldog, modern day pitbull, with several breeds of the mastiff with a few other breeds thrown in. The modern day pitbull, the original bulldog has changed very little from the dog of many centurys ago. You can put a picture of a modern day A.D.B.A. confirmation show champion against the ancient pictures of the original bulldog and see very little differences in the dog. It has been used in many of the different breeds to improve the health and stamina of dogs bred mainly for a certain look or color. It has been used in modern days by the A.K.C. which has allowed certain handpicked breeders to infuse the pitbull blood in their lines to improve the health of ceretain breeds and allowed these breeders to register their dogs as pure breeds. The pit bull should not have a wide chest but a deep chest for better breathing. Its legs should be set squarely under the dog and be such a length to give the dog great leverage. The body should be muscular without being bulky, this dog is an athalete. Many people will not agree with this history of the pitbull and I can't say it is the correct history. It is one I was taught many years ago with records, pedigrees, and pictures handed down from many generations. As I am an older man these records have been handed down to a younger man who has shown an interest in the dogs. Hope this will give someone else interested in the dogs a different outlook on a dog I consider to be the one of the original three styles of dogs developed by man.
