  Eliminating Genetic Diseases in Dogs: A Buyer's Perspective
While genetics can be a very complex technical subject, the basic information required to make progress toward the elimination of genetic disease by developing an effective breeding program is within the reach and understanding of everyone concerned.
Veterinarians should be able to recognize genetic diseases, and inform owners, breeders, and prospective breeders of their presence in dogs they examine and treat.
If genetic diseases are associated with conformance characteristics in an inseparable way, breed standards could be modified to eliminate the incentive for breeding to those characteristics once the underlying association has been identified.

  Genetic disorder - Wikipedia, the free encyclopedia
A genetic disorder, or genetic disease is a disease caused by abnormal expression of one or more genes in a person causing a clinical phenotype.
There are genetic disorders caused by the abnormal chromosome number, as in Down syndrome (extra chromosome 21) and Klinefelter's syndrome (a male with 2 X chromosomes).
Genetic diseases are typically diagnosed and treated by geneticists.

 The Nature of Genetic Disease
However, though there are legitimate genetic diseases, there are also a variety of problems that have an inherited component, but are of a fundamentally different nature.
Problems such as hip dysplasia and bloat clearly have a genetic component, but also an environmental component, and perhaps a behavioral one as well (which may also be partially determined by the genes).
Leaving aside the question of the role of genetics in behavior, the results suggest that the incidence of bloat increases with the size of the dog and the depth and width of the chest cavity.

Genetic diseases are a major health problem in purebred dogs, but reducing the occurrence of these primarily recessive diseases is difficult.
Diseases caused by mutations in autosomal genes are classified according to whether one or two copies of the mutant gene are needed to produce disease.
Dominant diseases tend to be less troublesome to breeders than are recessive diseases: A dominant disease is often detected before an animal is bred, and thus that animal is not used for breeding.

 The Nature of Genetic Disease
Many people label any problem that appears to be inherited a "genetic disease." However, though there are legitimate genetic diseases, there are also a variety of problems that have an inherited component, but are of a fundamentally different nature.
Gastric torsion is not a genetic disease, and it would be foolish to think that one can identify a single gene responsible for bloat.
Wherever there is genetic variability, one can select for larger, smaller, narrower, wider, etc. Because the fancy as a whole decided that a taller, narrower Standard Poodle looked more "refined", more of that description were kept for breeding purposes and the population has been shifted toward a more bloat-prone conformation.

 Genetic Diseases - CureResearch.com
These diseases are usually congenital and in-born, though depending on what parts of the body these genetic errors affect, the actual symptoms may arise either immediately or after delay.
A true "genetic disease" is one that is related to a single gene in one part of the DNA on one chromosome.
Hence, a genetic disease is a condition caused by a small error in the genetic code.

 Genetic Disease Information
A genetic disorder is a disease caused by abnormalities in an individual’s genetic material (genome).
Because chromosomes are carriers of genetic material, such abnormalities in chromosome structure as missing or extra copies or gross breaks and rejoinings (translocations), can result in disease.
With specialized backgrounds in medical genetics and counseling, genetic counselors work with medical personnel (usually M.D. Medical Geneticists) to give information, answer questions, and offer support to persons and families who have genetic disorders, are undergoing gene testing, or may be at risk for inheriting genetic disorders.

 Eliminating Genetic Diseases in Dogs: A Buyer's Perspective
Because some of the diseases exhibited by dogs are also evident in humans (vWD is the most common human inherited blood disease) some benefit could derive from canine research which would be of use in pursuing the human form of the same, or related, diseases.
For genetic diseases to be eliminated, they should be given at least as much weight as the other factors considered when breeding a dog - principally conformation and behavioral traits.
The incentives provided for the breeding of dogs without genetic diseases should be at least as good - probably better - than exist today.
