One of the technological tools in determining what makes humans, human is DNA testing. On many a daytime sensational talk show, the question “Who is the Father?” is answered through DNA testing. The same rationale and modes applies to dogs. Today, people can use the DNA code within the genetic make-up of their favorite pooch to discover a variety of information.

What is DNA?

DNA is the basic building blocks of mammals. The genetic code of who your canine is lies within the nuclear DNA. This exists within the cells of the body. Among dogs, approximately 19,000 canine genes have been recorded. Of this number, your dog has about 14,200 in common with humans. The rest are uniquely canine.

A dog’s mitochondrial DNA (mtDNA) is different without about 99.9% inherited from the mother. Doggy DNA reveals the breed difference in the microsatellite DNA. This is the repeated sequences along the chain.

What Does DNA Testing Involve?

DNA testing is a simple process. Depending upon the actual process, you will send a sample of your dog’s blood, hair or other part to the specified genetic laboratory for testing. You can swab the inside of your dog’s mouth with a Q-tip, place it in a sealed vial and send it off. Some labs and testing facilities may require samples from your dog and both the parents. This is if the issue of the canine’s parentage is questionable.

You then send it off to any of the services advertised on line. Alternatively, you can actually purchase a kit. You can then perform the case at home.

Why do DNA Testing?

There are several reasons behind DNA testing of your dog. Some pertain specifically to breeders and potential owners. Others are part of the owner’s decision to discover the heritage or ancestry of their mixed breed canine. Essentially, the reasons for doing DNA testing fall into the following major categories.

* Information on the degree of purity of their dog – Some breeders provide you with DNA evidence of the purebred nature of their line of dogs. For possible purchasers, it is one way of making sure their canine is purebred and not a close-match
* Information on the ancestry of the dog – Researchers are using DNA to map the history of the dog. By using DNA they have discovered the closest ancestors of the dog and are continuing to find more information about the early origins
* Information on what type of dog you have – Owners with mixed breeds want to know what kind of dog they have. They want to identify their beloved mutt’s breed mix.
* Health issues – If you have a mixed breed, you may want to identify the major contributing breeds to look for potential health risks. If you have a purebred dog, you want to screen for health risks. Does your dog carry a specific gene common to some breeds of dogs or only in a small percentage of the breed? DNA testing will help screen for inherited diseases

DNA testing can do all these things, but there are limitations. The DNA bank may contain a finite number of identifiable breeds. Check with the service you are employing before you decide to opt for a test.


DNA testing is a tool for researchers, vets, breeders, owners and potential owners to learn more about their canine. It can help screen for genetic disorders and health risks. It can verify parentage and perform genotyping. For some individuals, it helps them access the risk to their dog while, for others, DNA testing is a fun way to discover what breeds of dog make up their beloved mutt.
