Dog breeding is the vocation of mating carefully selected specimens of the same dog breed in order to reproduce specific, consistently replicable qualities and characteristics.

History of dog breeding[edit]

The relationship between humans and dogs is an ancient one. Cave paintings such as one found in Tassili-n-Ajjer suggest that primitive man and dog were already living in harmony. ^[1] By the time of the pharaohs, dogs had already established their value as workers and human companions. Egyptian paintings show that selective breeding had already begun; sighthounds were clearly identified. Later, Pliny the Elder referred to the existence of--if not refined dog breeds as we know them today, at least well-defined defined dog types. The Greeks and the Romans certainly bred dogs for specific, replicable qualities.^{[2] [3]}

By the medieval period, humans had realised that dogs could be selectively bred to pass on traits suited to the kinds of work they were expected to perform. There were herders, guard dogs, cart pullers, hand and bed warmers, status symbols, hunting hounds and terriers; hunters had even classified dogs according to the type of game they were best suited to handle.^[4]. There were restrictions on the size of dogs the underclasses could own, no non-noble hunters were likely among the earliest modern dog breeders. By the 16th Century, the first written work specifically and exclusively about dogs appeared ^[5] Dogs were used in sport and as vermin eradicators.

The rise of fox hunting as a pleasure sport in the 17th & 18th Centuries exposed the need for a better hunting terrier. Indeed, the fox terrier would later become the first of the codified terrier breeds. ^{[6] [7]} The less gentlemanly (but more accessible) sport of rat baiting also contributed to the selective breeding of small dogs. The continual refinement of dogs and dog breeds is clearly documented in western art.

Who is a dog breeder?[edit]

Who is best qualified to be a dog breeder, and what constitutes proper dog breeding is at the core of many arguments in the hobby of dog fancy. Fanciers do tend to agree on what are not good reasons for dog breeding: providing a sex education experience for children, making money and experimental breeding top the list of disparaged motives.

At its best, breeding is a blend of science and art. The skilled breeder has at least general knowledge of dog genetics and health, and in-depth knowledge of the breed standard and conformation points of his chosen breed. Dog breeders agree that care for the development of the breed and concern for the health and wellbeing of each individual animal must be uppermost in a breeder’s motivation.

At worst, breeding can be a slip shod enterprise in which the major concern is profit, with little regard to the health and welfare of the dogs involved. These often take the form of so-called ‘backyard breeders’ (the term for random or ignorant breeding conducted on a small scale), and ‘puppy mills’ or ‘puppy farms’ (larger businesses). It must be pointed out, however, that many excellent breeders run small-scale programs in their homes, barns or back yards, and there are profitable large-scale business operations run with knowledgeable staff and superlative veterinary care, so size and motive alone are not indicative of the quality of the breeding program.

The birth of a litter of purebred puppies is recorded in a breed registry. These are maintained by organizations whose primary concern is securing the lineage records of the breed. Kennel clubs are one example of these, but such registries are not the exclusive province of show dogs, as is sometimes thought; the clubs of working dogs also maintain records of their dogs’ lineage.

Breeder qualifications[edit]

Requirements for the breeding of registered purebreds vary from club to club. Members may have to open their kennel facilities initially or periodically for inspection by the Registry, and/or pass tests to determine their breeding knowledge.

Brood stock qualifications[edit]

Most kennel clubs allow for any registered puppy to be bred from once it reaches a suitable age. Established breeder are sometimes conservative about selling entire animals for breeding, as poor issue may reflect badly on their kennels. Some clubs maintain an adjunct or limited register, for puppies of purebred parents not deemed to have the qualities for showing or breeding, or who exhibit a fault. A few breed clubs, such as the Swiss breed club of the Greater Swiss Mountain Dog, the Jack Russell Terrier Club of America and the Mini Foxie Club of Australia have additional, strict requirements for the certification of adult dogs before breeding.

With the advent of genetic testing, many registries are considering it advisable to test breeding dogs before mating, and some have made such tests mandatory. Among the genetically-transmitted conditions that can be screened are:

• Genetic blindness
• Genetic deafness
• Hip and/or elbow dysplasia
• Luxating patella

In addition to the reguirements of the registering authority, the owners of stud dogs and brood bitches may have their own conditions of mating. Kennels are said to be open (dogs standing at stud and bitches to be serviced by outside males) or closed, where no outside matings are allowed. These days, many owners with dogs "standing at stud" state that these are available "to approved bitches only", meaning that the stud owner will not allow mating with bitches deemed to be in any way undesirable.

A person wishing to start in dog breeding must therefore first learn about the breed and how to choose quality breeding animals, then they must find animals of good quality for sale that they can afford, and then find suitable mates. The process can be extremely time-consuming and there is a great deal of anecdotal evidence from new breeders finding it difficult to start in dog breeding due to the reluctance of established breeders to sell or share their stock.
