DNA Testing for Dogs
DOG OWNERS CAN BENEFIT FROM NEW DOG DNA ANALYSIS TEST
A new DNA analysis test which will allow dog owners to check their
dog's parentage has recently been launched by Rosgen Ltd. The
technology, trialed in the US, can determine and record a dog's unique
genetic pattern, called a genotype, using only a sample taken from inside
the dog's cheek.
When there is a mixed litter, by using DNA analysis owners will be able to
identity which dog sired which puppy.
If a dog is lost or stolen, the DNA identification is tamperproof and can
indisputably link the dog to its owner, as a second sample can be taken
for genetic comparison to confirm the dog's identity.
And the opportunity to check a dog's parentage will allow greater
protection for anyone buying a dog, as well as adding value to the dog
for the breeder.
What is DNA Analysis?
Although dogs often look very alike, they are all unique, with their own
genetic pattern. This can be accessed by using DNA analysis.
Deoxyribonucleic acid (DNA) is the permanent genetic blueprint that
determines every heritable trait of a living organism. With the exception of
identical twins each living organism has its own unique DNA code.
DNA analysis can reveal a dog's genotype, which is fixed at the moment
of an animal's conception and remains constant for the dog's life. The
genotype can be determined using a sample from the inside surface of
the dog's cheek which is obtained using a soft-bristled brush, a process
easier than taking a blood sample, and returned to the laboratory for
processing.
The test results are then interpreted and documented onto a certificate
which shows the genetic analysis at selected different sites, using a
coloured bar code with different combinations of letters. All the genotypes
will be held on a computer database. The special introductory discounted
price for the test is £30 (inc VAT) per dog.
The future for Genetic Dogprints
There is enormous potential for using genetic analysis as a canine
breeding tool. Ultimately research will play a key role in the elimination of
specifically targeted diseases, such as canine hip dysplasia.
It also offers judging organisations a new tool to protect and enhance the
distinction of awards. They can periodically verify a dog's identity as it
earns awards towards championship titles.
DNA-based evidence is admissible in court and has been used for
evidence in lawsuits against animal smugglers.
