Breeding dogs has been a passion for people through many centuries. Part art, part science and total devotion, breeding will show you all the best in the human-and-dog bond. It is exciting and challenging. Breeding purebred dogs is also time consuming, expensive and, occasionally, heartbreaking. If you go forward, your underlying purpose should be to improve the breed - not just increase its numbers - and you must be prepared to accept full responsibility for the puppies from the moment they are born until the day they die.
Following is the summary of different types of breeding employed by successful breeders to produce a true breed type:-
Inbreeding is a mating of two individuals that are related through one or more common ancestors. Example of this are litter brother to litter sister, Sire to daughter, or mother to son, etc. Inbreeding is not a recommended form of breeding, dogs expect in certain very experience breeders programs, usually done one time only for that one purpose.
Linebreeding is a form of inbreeding, usually invloves mating more distantly related dogs. Good line breeding will produce your best dogs who will in return produce even better dogs if done right. Line breeding will give you much higher constant results producing dogs of the same type, size, quality, traits and temperments.
Outcross is the mating of two dogs of the same breed that are otherwise virtually unrelated. Breeding dogs this way only leads to many uncertain factors and can bring in many things a breeder is unaware of or even make it impossiable to pin point were a trait or problem have come from. 
Most successful breeders use some formula involving general line breeding with inbreeding employed when sufficiently outstanding products of their line result and outcrossing only when another line can supply a strong characteristic in which they are lacking.
