Dog DNA tests have become quite common these days. Previously after adopting a mixed breed dog, it was impossible to know about its personality traits and the diseases that it might suffer in the future etc. But now, thanks to DNA tests, this has become very much simpler. After the first DNA breed identification test was conducted it was found that genetic variation between human populations is about 5.4 percent. In case of dogs, this variation was estimated to be around 27.5 percent. This opened up new avenues for DNA testing. In 2005,the scientists signed an agreement with Mars Veterinary to introduce a series of tests that can be conducted at home and can provide results in a simple and effective manner.

Now there are many companies that have their own range of dog DNA tests. The dog dna test instructions tests also help with training by giving the owner a sneak peek into the behaviour of the dog. Also the tests are quite effective in determining whether the dog is susceptible to a particular type of genetically linked disease. But according to many company executives, a majority of the people purchase these tests just out of curiosity in order to know about the breed of their dog.

Some of these DNA breed identification tests are confined to a particular region. For example North America and they will be able to identify only certain breeds of dogs. Worldwide it is observed that there are currently more than 300 breeds of dogs. Hence the need of the hour is to produce tests with more genetic markers and disease recognising traits. Each company in the market currently has a different set of markers which define the breeds in their databases and utilizes modern computer algorithms to match the DNA of a dog to the ones in its database.
