Genetic Testing for Dogs

For some dog owners, genetic testing is a way to prove that they own a purebred dog or the descendant of a specific dog. Other dog owners use genetic testing out of curiosity to determine exactly what breeds comprise their pet. Genetic information has the potential to do more than prove lineage or satisfy curiosity: this testing may one day help to determine what heath problems a particular dog may be prone to and may one day provide the key to eliminating some canine illnesses.

Home Testing

Home kits for genetic testing are available for around $65. These tests allow pet owners to collect a DNA sample at home and then send the sample to a lab for testing.

DNA Sample Acquisition

Genetic testing is usually done using a saliva sample. This sample is acquired by rubbing a cotton swab on the inside of the dog's cheek.

Identification

Through genetic testing, it is possible to determine what breeds are present in mixed breed dogs with a 90 percent accuracy rate. The American Kennel Club and similar organizations can use genetic information to verify a dog's lineage.

Disease Markers

The information that has been gathered in the genetic databases of organizations such as the American Kennel Club is being used to try and identify the genetic markers that indicate certain canine diseases and other health problems.

Adoption Impact

Animal shelters believe that using genetic testing to determine a mixed dog's breeds will help increase the chance's of successful adoptions by providing more of a dog's background information to perspective owners. Genetic testing also allows shelter staff to make more informed decisions when matching the dog to the right owner.
